## [3.2.0] - 2024-09-18
## Highlights
This release brings a few minor breaking changes, both for the core project
and for the dbt templater. For the main project:
* Resolving an issue with the spacing of functions (LT01), which
involved a change to how functions are parsed. If your project relies
on the specific parsing of functions, the bracketed arguments are now
wrapped in a `function_contents` object. We recommend that you examine
the new parsing structure using this new release in testing first.
* `RF06` (`references.quoting`) is now case sensitive when removing
quotes which are detected as unnecessary. This rule has also been re-enabled
by default for Snowflake and Postgres where it had previously been disabled
(for the reason that in the past it hadn't been appropriately case
sensitive). Treatment for totally case-insensitive dialects like DuckDB
and SparkSQL have also been included. Please check the new documentation
for this rule (which is much more explicit now), for details related to
your dialect.
* Patterns equivalent to those from `.sqlfluffignore` can now be included
in `.sqlfluff` and `pyproject.toml` files.
* Using the `python` templater, users now have an option to include variables
which include a dot in the path, like `{{ foo.bar }}` using a special
`sqlfluff` context variable.
* Significant changes under the hood to the handling of configuration files.
Most of these should not be visible to end users, but for anyone integrating
SQLFluff into a larger project and relying on native file loading may need
to refactor their project for this release. Most notably here, for maintainers
of plugins, the `ConfigLoader` class has been deprecated, and plugins should
instead call the config loading functions directly. See the example plugin
for details.
* Documentation, especially for dialects, has been significantly improved.
Documentation for `CP02` (`capitalisation.identifiers`) has also been
clarified to make it's implication for references and aliases more clear.
* During testing, to isolate the effect of specific rules, there's a new
CLI option `--disable-noqa-except` which allows all `noqa` options to
be ignored _except_ the ones provided in this option.
For the dbt templater:
* Support for dbt 1.1-1.3 has been removed. All have been in End of Life (EOL)
support by dbtlabs for almost two years. They are also poorly supported by
other projects and tools.
* The dbt templater has been migrated to use `pyproject.toml`.
* Handling of errors and exceptions raised within dbt has had an overhaul.
Users may see a slightly different presentation of errors, but the overall
stability should be more robust.
In addition to those changes, there have been too many dialect contributions
and bugfixes to mention specifically. We've also seen **six** people make their
first contributions to the project as part of preparing for this release! 🎉🏆🎉.

## [3.1.1] - 2024-08-20
## Highlights
This release brings a bumper lot of bugfixes, dialect improvements and other
minor improvements across the board. Most notably:
* A rework of the structure of the docs. **NOTE**: This does change the url
of some docs pages, but to prevent future moves, we've also provided
permalinks to most important pages and rules. See the `conf.py` file in
the `docs` folder for a full list of permalinks.
* Solving rule conflicts between LT02 & LT02.
* Bugfixes to AM07, CV11, ST03, ST05 & RF03,
* Removes some redundant dependencies in for the dbt templater (which haven't
been required for some time, but have been included in the install dependencies).
Specifically: `markupsafe`, `ruamel.yaml`, `pydantic` & `rich`.
* And too many dialect improvements to summarise!
We've also seen **eleven** new contributors to the project! Thanks to all of them
for taking the time to contribute. 🎉🎉🏆🎉🎉

## [3.1.0] - 2024-07-03
## Highlights
This minor release has two breaking changes:
- The addition of camelCase in the extended capitalisation policy. This change removes the ability to
autodetect PascalCase, from now on PascalCase, and camelCase must be explicitly set in the config if desired.
- The detection method for sqlfluff config has changed. It should now be more consistent, regardless of how deep if the directory
structure you run the command from.
This release also brings in support for the MariaDB dialect. As well as this, there are many bugfixes,
and dialect improvements.
Thanks also to the **twelve** new contributors whose work was included
in this release! 🎉🎉🏆🎉🎉

## [3.0.2] - 2024-03-17
## Highlights
This is primarily another hotfix release for 3.0.0. Specifically making sure the
deprecation warnings for `-f/--force` go to `stderr` rather than `stdout`. It also
includes two dialect improvements, one for Snowflake and one for T-SQL.

## [3.0.1] - 2024-03-13
## Highlights
This minor release is a hotfix to resolve a bug introduced affecting CLI exit codes
in the 3.0.0 release.
## What’s Changed
* Fix 5673 [#5676](https://github.com/sqlfluff/sqlfluff/pull/5676) [@alanmcruickshank](https://github.com/alanmcruickshank)
## [3.0.0] - 2024-03-12
## Highlights
This release brings several breaking changes to previous releases. Most notably:
* It drops support for python 3.7, which reached end of life in June 2023.
* It migrates to `pyproject.toml` rather than `setup.cfg` as the python
packaging configuration file (although keeping `setuptools` as the default backend).
* The serialised output for `sqlfluff lint` (and the corresponding API methods)
now contains more information about the span of linting issues, initial
proposed fixes and several statistics which were previously only accessible via
csv export. Beside the *new* fields, the original fields of `line_pos` and
`line_no` have been renamed to `start_line_pos` and `start_line_no`, to
distinguish them from the new fields starting `end_*`.
* The default `annotation_level` set by the `--annotation-level`
option on the `sqlfluff lint` command has been changed from `notice`
to `warning`, to better distinguish linting errors from warnings, which
always now have the level of `notice`. This is only relevant when using
the `github-annotation` or `github-annotation-native` formats.
* A change in the default behaviour for `convention.not_equals`. The new default
is to be `consistent`, which is slightly more relaxed than the original
behaviour.
* The `--force` option has been deprecated on `sqlfluff fix` as that option is
now the default behaviour. This is to enable significant reductions in memory
overhead when linting large projects.
* The long since deprecated `--disable_progress_bar` option has been removed
(which was replaced by the kabab-case `--disable-progress-bar` more than a
year ago).
* Plugins are now loaded progressively, and with error handling. If a plugin
fails to load, SQLFluff will now continue onward and try to run regardless
while also showing a more helpful error message.
On top of these changes, there have a been a whole host of dialect improvements
and additions, in particular the inclusion of a`vertica` dialect for the
first time. There's also:
* A new rule (`aliasing.self_alias.column`) which prevents aliasing a column as itself.
* A change to disables AL01 (`aliasing.table`) by default for Oracle.
* A change to allow AL05 to allow aliasing for a `VALUES` clause.
For more specifics please take a look at the
[release notes](https://docs.sqlfluff.com/en/latest/releasenotes.html).
Thanks to the community for patience during the release cycle for 3.0.0, which
has taken a little longer than expected. Thanks also to the **TWENTY SEVEN** new
contributors whose changes are included in this release. 🎉🎉🏆🎉🎉

## [3.0.0a6] - 2024-03-05
## Highlights
This introduces some memory optimisations in the linting operation which
prevent a major cause of crashes when linting large projects. As part of that
we've also deprecated the `--force` option on `sqlfluff fix` and made that
the default behaviour (the associated memory optimisations will come shortly).
This also removes the long since deprecated `--disable_progress_bar` option
(which was replaced by the kabab-case `--disable-progress-bar` more than a
year ago).
On top of that this release also introduces the `vertica` dialect for the
first time, and a whole host of bugfixes and improvements to other dialects.
This release should be considered a release candidate for the final `3.0.0`
release which will follow shortly in the next few days unless any other
major issues are found.
Thanks particularly to the **seven** new contributors we saw in this release 🏆🎉.

## [3.0.0a5] - 2024-01-30
## Highlights
This release primarily brings through a large set of dialect improvements and
bugfixes from over the holiday period. Notably also:
* A change in the default behaviour for `convention.not_equals`. The new default
is to be `consistent`, which is slightly more relaxed than the original
behaviour.
* A new rule (`aliasing.self_alias.column`) which prevents aliasing a column
as itself.
* Disables `AL01` (`aliasing.table`) by default for Oracle.
This release also saw **ELEVEN** new contributors in this release 🎉🎉🏆🏆🎉🎉.
Great to see so many new people getting involved with the project. Thank You 🙏.

## [3.0.0a4] - 2023-12-05
## Highlights
This release makes a breaking change to the serialized output of the
CLI (and by extension, any of the serialized outputs of the API).
* The serialised output for `sqlfluff lint` now contains more information
about the span of linting issues and initial proposed fixes. Beside the *new*
fields, the original fields of `line_pos` and `line_no` have been
renamed to `start_line_pos` and `start_line_no`, to distinguish
them from the new fields starting `end_*`.
* The default `annotation_level` set by the `--annotation-level`
option on the `sqlfluff lint` command has been changed from `notice`
to `warning`, to better distinguish linting errors from warnings, which
always now have the level of `notice`. This is only relevant when using
the `github-annotation` or `github-annotation-native` formats.

## [3.0.0a3] - 2023-11-29
## Highlights
This brings no further _breaking_ changes on top of `3.0.0a2`, but instead
releases a few of the more minor fixes flowing through while other breaking
changes are staged in. In particular there are a few dialect improvements
for Snowflake, TSQL, SQLite and Databricks alongsids a few further
improvements to deployment scripts off the back of earlier changes for `3.x`.

## [3.0.0a2] - 2023-11-09
## Highlights
The initial 3.0.0a1 release failed to build a docker image, this resolves
that issue.
## What’s Changed
* Update publish actions and Dockerfile. [#5390](https://github.com/sqlfluff/sqlfluff/pull/5390) [@alanmcruickshank](https://github.com/alanmcruickshank)
## [3.0.0a1] - 2023-11-08
## Highlights
This release makes a couple of potentially breaking changes:
* It drops support for python 3.7, which reached end of life in June 2023.
* It migrates to `pyproject.toml` rather than `setup.cfg` as the python
packaging configuration file (although keeping `setuptools` as the default backend).
Further breaking changes may be made as part of the full 3.0.0 release, but this
alpha release is designed to test the new packaging changes for any issues before
releasing a stable version.

## [2.3.5] - 2023-10-27
## Highlights
This is a fairly minor release, primarily bugfixes and dialect improvements.
For python API users, there's the addition of a public method on the `FluffConfig`
object allowing the construction of a config object from multiple strings to
mimic the effect of nested config files in the CLI.
This release also includes a selection of internal refactoring and reorganisation
to support future development work.
This also sees the first contributions by [@ShubhamJagtap2000](https://github.com/ShubhamJagtap2000)
& [@kang8](https://github.com/kang8), particularly notable in that both were
contributions to SQLFluff documentation! 🎉🎉🏆🎉🎉

## [2.3.3] - 2023-10-13
## Highlights
There's a *lot* in this release. Most of it is under the covers and so shouldn't
cause any breaking changes for most users. If your use case depends on some of the
internals of SQLFluff, you may find some breaking changes. The bigger changes are:
- Python 3.12 support is now official (although older releases may also work as
only a few changes were required for full 3.12 support).
- We've done a significant re-write of the parsing engine to remove some unnecessary
segment manipulation and get us closer to "single pass" parsing. This changes the
internal API being used on any `.match()` methods, and also removes the
`parse_grammar` attribute on any dialect segments. We are not aware of any 3rd party
libraries which rely on these APIs however and so have not triggered a more major
release. These lead to significant performance improvements during parsing.
- Standardisation of terminators in the parser, and the introduction of the `ParseMode`
option has enabled the removal of the `StartsWith`, `GreedyUntil` and
`EphemeralSegment` parser classes.
- Several validation checks have been revised in this release, which should both
improve performance (by reducing duplication), but also be more effective in
preventing the application of any fixes which would result in unparsable files.
Alongside the big things this also includes a host of bugfixes, dialect improvements
and CI/testing improvements.
This release also sees a bumper crop of new contributors, thanks to

## [2.3.2] - 2023-09-10
## Highlights
Much of this release is internal optimisations and refactoring. We're in the
process of upgrading some quite old code in the parser, most of which should
not be visible to end users (apart from perhaps some performance improvements!).
This release also allows missing template variables in the placeholder templater
to be automatically filled with the name of the variable rather than raising
an error (see: [#5101](https://github.com/sqlfluff/sqlfluff/pull/5101)).
Beyond that this includes some dialect improvements for DuckDB, SparkSQL,
Snowflake, Redshift & Postgres.
Thanks particularly to [@shyaginuma](https://github.com/shyaginuma), [@Fullcure3](https://github.com/Fullcure3),
[@adilkhanekt](https://github.com/adilkhanekt) & [@pilou-komoot](https://github.com/pilou-komoot)
who made their first contributions as part of this release. 🎉🎉🎉

## [2.3.1] - 2023-08-29
## Highlights
This release is primarily a performance release, with most major changes
aimed at the linting and fixing phases of operation. Most of the longest
duration rules (excepting the layout rules) should see noticeable speed
improvements.
Alongside those changes, there are a selection of bugfixes and dialect
improvements for Oracle, PostgreSQL, Snowflake & TSQL.

## [2.3.0] - 2023-08-14
## Highlights
This release brings one new dialect, two new rules and some changes to the CLI:
- We now support the [trino](https://trino.io/) dialect. This is a first version of
support, so do post any issues on GitHub in the usual way. This was also the first
contribution to the project from [@efung](https://github.com/efung) 🏆.
- `ST09` / `structure.join_condition_order`: Which checks whether tables referenced
in `JOIN` clauses are referenced in the order of their definition. By default
this means that in the `ON` clause, the column referencing the table in the
`FROM` clause should come before the column referencing the table in the `JOIN`
clause (e.g. `... FROM a JOIN b on a.c = b.c`). This rule was also the first
contribution to the project from [@thibonacci](https://github.com/thibonacci) 🏆.
- `AL08` / `aliasing.unique.column`: Which checks that column aliases and names
are not repeated within the same `SELECT` clause. This is normally an error
as it implies the same column has been imported twice, or that two expressions
have been given the same alias.
- The `--profiler` option on `sqlfluff parse` has been removed. It was only
present on the `parse` command and not `lint` or `fix`, and it is just as simple
to invoke the python `cProfiler` directly.
- The `--recurse` cli option and `sqlfluff.recurse` configuration option have
both been removed. They both existed purely for debugging the parser, and were
never used in a production setting. The improvement in other debugging messages
when unparsable sections are found means that this option is no longer necessary.
Along side these more significant changes this also includes:
- Performance optimisations for `AL04`, `AL05`, `AM04`, `RF01` & `ST05` which
cumulatively may save up to 30% on the total time spend in the linting phase
for some projects.
- Dialect improvements for Oracle & TSQL.

## [2.2.1] - 2023-08-09
## Highlights
This is primarily a bugfix release for 2.2.0 which introduced
a bug in the `exit_code` returned by linting commands which ignored errors
while setting `processes > 1`.
In addition to that this release introduces bugfixes for:
- Errors raised by two specific `dbt` exceptions.
- Issues with unwanted logging output when using `-f yaml` or `-f json`
alongside the `dbt` templater.
This also introduces dialect improvements for Oracle and for `LIMIT` clauses.

## [2.2.0] - 2023-08-04
## Highlights
This release changes some of the interfaces between SQLFluff core and
our plugin ecosystem. The only *breaking* change is in the interface
between SQLFluff and *templater* plugins (which are not common in the
ecosystem, hence why this is only a minor and not a major release).
For all plugins, we also recommend a different structure for their
imports (especially for rule plugins which are more common in the
ecosystem) - for performance and stability reasons. Some users had
been experiencing very long import times with previous releases as
a result of the layout of plugin imports. Users with affected plugins
will begin to see a warning from this release onward, which can be
resolved for their plugin by updating to a new version of that plugin
which follows the guidelines.
For more details (especially if you're a plugin maintainer) see our
[release notes](https://docs.sqlfluff.com/en/latest/releasenotes.html).
Additionally this release includes:
- Some internal performance gains which may cumulatively save
roughly 10% of the time spent in the parsing phase of larger files.
- Improvements to the Simple API, including the ability to pass in
a `FluffConfig` object directly, and better support for parsing
config files directly from strings (see
[the included example](examples/05_simple_api_config.py)).
- A bugfix for `AM06`.
- A new `--warn-unused-ignores` CLI option (and corresponding config
setting) to allow warnings to be shown if any `noqa` comments in
SQL files are unused.
- Improvements to Redshift, Oracle, Clickhouse, Materialize &
MySQL dialects.
- A selection of internal improvements, documentation and type hints.

## [2.1.4] - 2023-07-25
## Highlights
This release brings some meaningful performance improvements to the parsing of
complex SQL statements. In files with deeply nested expressions, we have seen
up to a 50% reduction on time spent in the parsing phase. These changes are all
internal optimisations and have minimal implications for the parser. In a few
isolated cases they did highlight inconsistencies in the parsing of literals
and so if your use case relies on the specific structure of literal and
expression parsing you may find some small differences in how some expressions
are parsed.
Additionally this release brings new validation steps to configuration.
Layout configuration is now validated on load (and so users with invalid
layout configurations may see some of these being caught now) and inline
configuration statements in files are also now validated for both their
layout rules and for any removed or deprecated settings.
On top of both we've seen dialect improvements to Databricks, PostgreSQL,
BigQuery, Snowflake & Athena.

## [2.1.3] - 2023-07-19
## Highlights
This release is a fairly standard incremental release. Highlights include bugfixes
to `RF05` and dialect improvements to Snowflake, Teradata, MySQL, TSQL, SparkSQL & Postgres.
Internally, the last few weeks have brought several improvements to developer tooling.
We've also moved over to GitHub sponsorships - so if you previously used the old
flattr link, you can find our new profile page at https://github.com/sponsors/sqlfluff.

## [2.1.2] - 2023-07-03
## Highlights
This release resolves compatibility issues with a set of `dbt-core` versions.
- `dbt-core` 1.5.2 onwards is now properly supported.
- support for `dbt-core` 1.1 to 1.4 has now been re-enabled after
support had to be abandoned a few releases ago.
NOTE: We cannot guarantee that SQLFluff will always continue to remain
compatible with all dbt versions, particularly as the folks at dbt-labs
have often backported breaking changes to their internal APIs to previous
versions of `dbt-core`. This release does at least bring more extensive
internal testing to catch when this does occur to allow our community
to react.
This release fixes also resolves a potential security issue for when
using external libraries (and the `library_path` config setting),
and also contains various dialect improvements.

## [2.1.0] - 2023-05-03
## Highlights
This release brings support for dbt 1.5+. Some internals of dbt mean
that SQFluff versions prior to this release may experience errors with

templating improvements bundled too:
* Support for custom Jinja filters.
* An additional configurable indent behaviour within `CASE WHEN` clauses.
* Additional support for bracket quoted literals in TSQL and RF06.
* Dialect improvements to Snowflake, Hive, Redshift, Postgres,
Clickhouse, Oracle and SQLite

## [2.0.2] - 2023-03-23
## Highlights
This is primarily a _bugfix_ release. Most notably this solves some of the
issues introduced in 2.0.1 around spacing within datatypes. Expressions
like `1.0::double precision` should now be spaced correctly.
Beyond that, this contains a selection of smaller bugfixes and dialect
improvements. Even for a relatively small release we saw three new
contributors (thanks [@aurany](https://github.com/aurany), [@JackWolverson](https://github.com/JackWolverson)
& [@mikaeltw](https://github.com/mikaeltw) 🎉).
The one new _feature_ (as such) is being able to now configure `LT05`
(aka `layout.long_lines`) to optionally move trailing comments _after_
the line they are found on, rather than the default behaviour of moving
them up and _before_. Users can enable this with the `trailing_comments`
configuration setting in the `indentation` section.
This release _also_ contains some performance optimisations in the parser,
especially on queries with heavily nested expressions. There will be more
to come in this space, but we hope this leads to a better experience for
many users. 🚀

## [2.0.1] - 2023-03-17
## Highlights
This is mostly a bugfix release addressing some of the issues from the recent
2.0 release. Notable fixes are:
- Spacing for (as applied by `LT01`) for datatypes, hyphenated identifiers and
casting operators.
- Several bugs in the indentation routines (`LT02`), in particular with implicit
indents.
- Fixing a conflict between `LT09` and `LT02`, by only limiting `LT09` to bringing
targets onto a single line if there is only one select target **and** that it
contains no newlines.
- Supporting arrays, and the new rules configuration more effectively in `pyproject.toml`.
- Configuring dialects on a file by file basis using inline comments now works.
This release also brings one small new feature in allowing additional flags to
be passed to SQLFluff when called as a `pre-commit` hook.
Thanks especially to [@JavierMonton](https://github.com/JavierMonton) and
[@LauraRichter](https://github.com/LauraRichter) who made their first contributions
to the project as part of this release! 🎉🏆

## [2.0.0] - 2023-03-13
## Highlights
Upgrading to 2.0 brings several important **breaking changes**:
* All bundled rules have been recoded, both from generic `L00X` formats
into groups within similar codes (e.g. an *aliasing* group with codes
of the format `AL0X`), but also given *names* to allow much clearer
referencing (e.g. `aliasing.column`).
* [Configuring rules](https://docs.sqlfluff.com/en/latest/configuration.html#rule-configuration)
now uses the rule *name* rather than the rule *code* to
specify the section. Any unrecognised references in config files (whether
they are references which *do* match existing rules by code or alias, or
whether the match no rules at all) will raise warnings at runtime.
* A complete re-write of layout and whitespace handling rules (see
[layout](https://docs.sqlfluff.com/en/latest/layout.html)), and with
that a change in how layout is configured (see
[configuring layout](https://docs.sqlfluff.com/en/latest/layout.html#configuring-layout))
and the combination of some rules that were previously separate. One
example of this is that the legacy rules `L001`, `L005`, `L006`, `L008`,
`L023`, `L024`, `L039`, `L048` & `L071` have been combined simply into
[LT01](https://docs.sqlfluff.com/en/latest/rules.html#sqlfluff.rules.sphinx.Rule_LT01).
* Dropping support for dbt versions before `1.1`.
To help users upgrade to 2.0, we've put together a recommended process
as part of our [release notes](https://docs.sqlfluff.com/en/latest/releasenotes.html#upgrading-from-1-x-to-2-0).
Beyond the breaking changes, this release brings *a load* of additional
changes:
* Introduces the the `sqlfluff format` CLI command (a la `sqlfmt` or `black`)
to auto-format sql files using a known set of _fairly safe_ rules.
* Databricks as a distinct new dialect (rather than as previously an alias
for `sparksql`).
* Performance improvements in our parsing engine.
* Dialect improvements to _almost all of them_.
As a new major release, especially with significant rewrites of large
portions of the codebase, we recommend using [compatible release](https://peps.python.org/pep-0440/#compatible-release)
specifiers in your dependencies (i.e. `sqlfluff~=2.0.0`) so that you
can automatically take advantage of any bugfix releases in the coming
weeks. The alpha releases of 2.0.0 have been tested on a range of large
projects, but we know that the range of use cases _"in the wild"_ is
very diverse. If you do experience issues, please post them
[on GitHub](https://github.com/sqlfluff/sqlfluff/issues/new/choose)
in the usual manner.

## [2.0.0a6] - 2023-03-06
> NOTE: This is effectively a release candidate for testing purposes.
> There are several new features here, and breaking changes to
> configuration. We welcome testing feedback from the community, and
> the intent is that following this release there will be no more
> major breaking changes in the before the 2.0.0 release.
## Highlights
This is the sixth alpha release for 2.0.0, and effectively the first release
candidate for 2.0.0. All the intended breaking changes for the upcoming
release have now been made and only bugfixes and non breaking feature
changes should happen between this release and the full release.
It contains:
* A reorganisation of rules. All rules have been recoded, and can now be
referred to by their name, code, alias or group. The legacy code for the
rule is included as an alias for each rule to support some backward
compatibility.
* Configuration files (and inline configuration flags), should now use the
**name** of the rule rather than the **code**. Any configuration files
which reference using legacy rules (or reference unknown rules) should
now display warnings.
* Introduces the the `sqlfluff format` CLI command (a la `sqlfmt` or `black`)
to auto-format sql files using a known set of _fairly safe_ rules.
* Databricks as a distinct new dialect (rather than as previously an alias
for `sparksql`).
There are also numerous dialect improvements to ANSI, Athena, TSQL, Teradata,
SQLite & MySQL.

## [2.0.0a5] - 2023-02-24
> NOTE: This is an alpha release for testing purposes. There are several new features
> here, and breaking changes to configuration. We welcome testing feedback from the
> community, but know that this release may feel less polished than usual.
## Highlights
This is the fifth alpha release for 2.0.0. It contains:
* Significant rework to rule naming and categorisation.
* Several performance improvements.
* Many dialect improvements to several dialects.
* Bugfixes to many of the issues raised in 2.0.0a4.
There will likely be more changes to rule classification before a full release of 2.0.0,
so anticipate that configuration files may change slightly again in future alpha releases.

## [2.0.0a4] - 2023-01-26
## Highlights
This is the fourth alpha release for 2.0.0. It contains a fix for the renamed dbt exceptions in dbt version 1.4.0, a fix for a major performance issue with the 2.0 dbt templater, and improvements to parse performance of large SQL files.

* Fix #4024 example plugin unit tests import [#4302](https://github.com/sqlfluff/sqlfluff/pull/4302) [@matthieucan](https://github.com/matthieucan)
## [2.0.0a3] - 2023-01-16
> NOTE: This is an alpha release for testing purposes. There are several new features
> here, and breaking changes to configuration. We welcome testing feedback from the
> community, but know that this release may feel less polished than usual.
## Highlights
This is the third alpha release for 2.0.0. It contains primarily bugfixes from 2.0.0a2
to allow continued testing. In particular, some of the recent 2.0.0-related changes to the
dbt templater have been reverted, primarily due to performance and other issues. If
those issues can be resolved, the changes will be re-introduced. The long-term goal of
this work is to ease maintenance of the templater by separating dbt integration concerns
from SQLFluff concerns.
There will likely be more changes to rule classification before a full release of 2.0.0,
so anticipate that configuration files may change slightly again in future alpha releases.

## [2.0.0a1] - 2022-12-28
## Highlights
This is the first alpha version for 2.0.0. It brings all of the changes to whitespace
handing, including a total rewrite of indentation and long line logic (L003 & L016).
That brings several breaking changes to the configuration of layout, see the
[layout docs](https://docs.sqlfluff.com/en/stable/layout.html) for more details and
familiarise yourself with the new
[default configuration](https://docs.sqlfluff.com/en/stable/configuration.html#default-configuration).
In addition, for the dbt templater, this introduces a large re-write of the codebase,
dropping support for dbt versions before 1.0.0. This leverages functionality from
[dbt-osmosis](https://github.com/z3z1ma/dbt-osmosis) to reduce the amount of
functionality supported directly by SQLFluff, and performance during testing of the new
version has been reported as significantly faster.

## [1.4.5] - 2022-12-18
## Highlights
This is a bugfix release, primarily for diff-quality. In addition, a new rules for spacing
around parenthesis is also included.
This is also the final 1.x.x release. Following releases will be a series of alpha releases
for 2.x.x. If you affected by any outstanding bugs or regressions from this release, consider
either rolling _backward_ to a previous release without those issues, or failing _forward_
to on an alpha release for 2.x.x (or a full release if that's out). Note that 2.x.x will bring
a selection of breaking changes to config file structure, rule categorisation and dbt support.
## What’s Changed
* Add rule for space around parenthesis [#4131](https://github.com/sqlfluff/sqlfluff/pull/4131) [@NelsonTorres](https://github.com/NelsonTorres)
* diff-quality plugin: Print invalid JSON on parse failure [#4176](https://github.com/sqlfluff/sqlfluff/pull/4176) [@barrywhart](https://github.com/barrywhart)

## [1.4.2] - 2022-11-13
## Highlights
This release is less about internals and much more about some quality of life
improvements and dialect changes. The most notable are:
- The introduction of a `sqlfluff render` command to preview the results of
templated sql.
- Linting errors within templated loops should now only appear once in the
linting output.
- Indentation around jinja `{% set %}` statements should now be more consistent.
- Linting errors around unparsable code are now more appropriately handled (with
more to come soon on that front).
- Error messages when specified files aren't found are now more specific.
We've also got dialect improvements for Redshift, SOQL & SparkSQL.

## [1.4.1] - 2022-10-31
## Highlights
This is a fix to the configuration migration from 1.4.0. In that release, the configuration
of leading/trailing operators would be migrated the wrong way around and precedence between
new and old configuration values behaved unexpectedly.
## What’s Changed
* Config precedence [#4007](https://github.com/sqlfluff/sqlfluff/pull/4007) [@alanmcruickshank](https://github.com/alanmcruickshank)
* Redshift CREATE/ATTACH/DETACH/DROP RLS POLICY statements [#4004](https://github.com/sqlfluff/sqlfluff/pull/4004) [@rpr-ableton](https://github.com/rpr-ableton)
* Redshift: Add support for APPROXIMATE functions [#3997](https://github.com/sqlfluff/sqlfluff/pull/3997) [@rpr-ableton](https://github.com/rpr-ableton)
* hotfix to config migration [#4005](https://github.com/sqlfluff/sqlfluff/pull/4005) [@alanmcruickshank](https://github.com/alanmcruickshank)
## [1.4.0] - 2022-10-31
## Highlights
This release brings several internal changes, and acts as a prelude to 2.0.0 which
will be released fairly soon. In particular, the following config values have changed:
- `sqlfluff:rules:L007:operator_new_lines` has been changed to
`sqlfluff:layout:type:binary_operator:line_position`.
- `sqlfluff:rules:comma_style` and `sqlfluff:rules:L019:comma_style` have both been
consolidated into `sqlfluff:layout:type:comma:line_position`.
If any of these values have been set in your config, they will be automatically
translated to the new values at runtime, and a warning will be shown. To silence
the warning, update your config file to the new values. For more details on
configuring layout (including some changes yet to come in future versions)
see [the docs](https://docs.sqlfluff.com/en/latest/layout.html#configuring-layout).
These changes are driven by underlying centralisation in the routines which control
layout. While for this release, no breaking changes are expected - you may find
slight differences in how SQLFluff handles edge cases. We believe in the majority
of cases these are _more_ consistent, but if you find any which are problematic
then do post an issue on GitHub as usual.
Other highlights from this release:
- Better dbt supportfor graph nodes and avoiding dependency conflicts.
- Numerous dialect improvements to T-SQL, MySQL, SparkSQL, SQLite, Athena
Snowflake, Hive, Postgres & Databricks.
There have also been first time contributions from **10 new contributors**! 🎉🎉🎉

## [1.3.2] - 2022-09-27
## Highlights
This is primarily a release for dialect fixes and improvements with additions
and changes to TSQL, Snowflake, MySQL & Redshift. The other changes of note are:
1. Support for warnings when users set old removed config values. This supports
future change work by allowing a mechanism to warn if they are used.
2. Improvements to the fix routines for L014 and L042 to handle some trickier
cases.

## [1.3.0] - 2022-08-21
## Highlights
This release brings several potentially breaking changes to the underlying parse tree. For
users of the cli tool in a linting context you should notice no change. If however
your application relies on the structure of the SQLFluff parse tree or the naming of certain
elements within the yaml format, then this may not be a drop-in replacement. Specifically:
- The addition of a new `end_of_file` meta segment at the end of the parse structure.
- The addition of a `template_loop` meta segment to signify a jump backward in the source
file within a loop structure (e.g. a jinja for loop).
- Much more specific types on some raw segments, in particular `identifier` and `literal`
type segments will now appear in the parse tree with their more specific type (which
used to be called `name`) e.g. `naked_identifier`, `quoted_identifier`, `numeric_literal` etc...
If using the python api, the _parent_ type (such as `identifier`) will still register if
you call `.is_type("identifier")`, as this function checks all inherited types. However the
eventual type returned by `.get_type()` will now be (in most cases) what used to be accessible
at `.name`. The `name` attribute will be deprecated in a future release.
Other highlights:
* New command-line option `--show-lint-violations` to show details on unfixable errors when
running `sqlfluff fix`.
* Improved consistency of process exit codes.
* Short CLI options for many common options.
* Jinja templater: When `--ignore=templating` is enabled, undefined Jinja variables now take
on "reasonable" default values rather than blank string (`""`). This can streamline initial
rollout of SQLFluff by reducing or eliminating the need to configure templater variables.
There are also a _ton_ of other features and bug fixes in this release, including first-time
contributions from **11 new contributors**! 🎉

## [1.2.1] - 2022-07-15
## Highlights
This is primarily a bugfix release to resolve an issue with the 1.2.0 release
where the new version of `sqlfluff-templater-dbt` relied on functionality
from the new version of `sqlfluff` but the package configuration had not
been updated. Versions of the two packages are now pinned together.
## What’s Changed
* Pin sqlfluff-templater-dbt via release script [#3613](https://github.com/sqlfluff/sqlfluff/pull/3613) [@greg-finley](https://github.com/greg-finley)
* Specifying comma delimited is unnecessary [#3616](https://github.com/sqlfluff/sqlfluff/pull/3616) [@alanmcruickshank](https://github.com/alanmcruickshank)
* Handle redshift temporary tables with # at the beginning of name [#3615](https://github.com/sqlfluff/sqlfluff/pull/3615) [@pdebelak](https://github.com/pdebelak)
## [1.2.0] - 2022-07-13
## Highlights
Major changes include:
* Adding AWS Athena as a dialect.
* A fix routine for L046 (whitespace in jinja tags), and the mechanisms for
more source-only fixes in future.
* By default, large files (over 20k characters) are now skipped by sqlfluff. This
limit is configurable and disable-able but exists as a sensible default to avoid
the performance overhead of linting *very* large files.
* For the dbt templater, fatal compilation errors now no longer stop linting, and
these files are now skipped instead. This enables projects to continue linting
beyond the offending file and much better logging information to enable better
debugging.

## [1.0.0] - 2022-06-17
## Highlights
This is the first _stable_ release of SQLFluff 🎉🎉🎉.
- _Does this mean there are no more bugs?_ **No.**
- _Does this mean we're going to stop developing new features?_ **No.**
- _Does this mean that this is a tool that is now broadly usable for many teams?_ **Yes.**
We've intentionally chosen to release 1.0.0 at a time of relative stability within SQLFluff and
not at a time when new big structural changes are being made. This means that there's a good
chance that this release is broadly usable. This also recognises that through the hard work
of a _huge_ number of contributors that we've built out this from a fringe tool, to something
which gets over 500k downloads a month and over 4k stars on Github.
There's still a lot to do, and some more exciting things on the horizon. If you want to be
part of this and join the team of contributors, come and hang out in our [slack community](https://join.slack.com/t/sqlfluff/shared_invite/zt-o1f4x0e8-pZzarAIlQmKj_6ZwD16w0g)
or on our [twitter account](https://twitter.com/SQLFluff) where people can help you get
started. If you're a long time user, keep submitting bug reports and inputting
on [issues on Github](https://github.com/sqlfluff/sqlfluff/issues).
If you've never used SQLFluff before, or are hesitant about starting to use it in your day
to day work, now might be a good time to try it. We have guides on how to [get started with the tool](https://docs.sqlfluff.com/en/stable/gettingstarted.html),
and how to [get started with rolling out to a team](https://docs.sqlfluff.com/en/stable/teamrollout.html) in our docs.

## What’s Changed
This release brings about several great new additions including:
- dbt 1.0.0 compatibility.
- CLI and Simple API parameters to provide custom paths to config files.
- Refinement to Simple API to return parse output in JSON format rather than as an internal SQLFluff object (**BREAKING CHANGE**).
- An [Official SQLFluff Docker Image](https://hub.docker.com/r/sqlfluff/sqlfluff).
- Grammar improvements across various dialects.
- A new rule (L057) to check for non-alphanumeric values in identifiers.
There have also been many bug fixes and improvements to the CI and development processes.

## [0.8.2] - 2021-11-22
## What’s Changed
One of the biggest new features in this release is the support for SQLAlchemy and other "placeholder" templating within SQL queries. Check out [the documentation on how to set it up](https://docs.sqlfluff.com/en/latest/configuration.html#placeholder-templating).
This release also adds **seven** new rules. Get some help with your leading whitespace, semi-colon placement, inconsistent column references in `GROUP BY/ORDER BY`, and getting rid of `RIGHT JOIN`'s among other useful lints with our new rules! See our [rules documentation](https://docs.sqlfluff.com/en/stable/rules.html) for more details.
On top of those, we have made loads of grammar improvements across many dialects, improvements to the dbt templater (including issues where `sqlfluff fix` would corrupt the code :scream:), more fix routines, and lots more improvements.

**BREAKING CHANGE**
This release extracts the dbt templater to a separately installable plugin
[sqlfluff-templater-dbt](https://pypi.org/project/sqlfluff-templater-dbt/).
For users who take advantage of the dbt templater see the
[updated docs on how to migrate](https://docs.sqlfluff.com/en/latest/configuration.html#installation-configuration).

## [0.6.0] - 2021-06-06
### Added
- Respect XDG base dirs on Mac OS ([#889](https://github.com/sqlfluff/sqlfluff/issues/889)).
- Added support for additional delimiters by creating a new DelimiterSegment in the
ANSI dialect which defaults to the semicolon, but allows it to be more intuitive
when overridden in a specific child dialect (mysql) [#901](https://github.com/sqlfluff/sqlfluff/issues/901))
- Added support for the DELIMITER statement in the mysql dialect [#901](https://github.com/sqlfluff/sqlfluff/issues/901))
- Added support for additional delimiters by creating a new DelimiterSegment in the
ANSI dialect which defaults to the semicolon, but allows it to be more intuitive
when overridden in a specific child dialect (mysql) [#901](https://github.com/sqlfluff/sqlfluff/issues/901))
- Added support for function as a default column value [#849](https://github.com/sqlfluff/sqlfluff/issues/849).
- Add an `--include-metas` option for parse output to show the meta
segments in the parse tree.
- Allow CREATE FUNCTION syntax without arguments [@bolajiwahab](https://github.com/bolajiwahab) [#1063](https://github.com/sqlfluff/sqlfluff/pull/1063).
- Added support for the CREATE/DROP PROCEDURE statement for the mysql dialect [#901](https://github.com/sqlfluff/sqlfluff/issues/901))
- Added specific allowed/required syntaxes for CREATE/DROP FUNCTION within the mysql dialect [#901](https://github.com/sqlfluff/sqlfluff/issues/901))
- Now possible to run sqlfluff commands outside the project root when using the dbt templater.
### Changed
- Renamed --parallel CLI argument to --processes to be more accurate.
- L034 now ignores select statements which contain macros.
- L034 now ignores select statements part of a set expression, most commonly a union.
- Fix bug [#1082](https://github.com/sqlfluff/sqlfluff/issues/1082), adding
support for BigQuery `select as struct '1' as bb, 2 as aa` syntax.
- Rationalisation of the placement of meta segments within templated
queries to support more reliable indentation. This includes prioritising
_longer_ invariant sections first and then dropping any shorter ones
which then are relatively out of place.
- Additional logging within the lexer and templater engines.
- Allow meta segments to parse within `Delimited` grammars which otherwise
don't allow gaps. This is facilitated through an optional argument to
`trim_non_code_segments`.
- Fix bug [#1079](https://github.com/sqlfluff/sqlfluff/issues/1079), addressing
issues with L025 and L026 with BigQuery column references involving `STRUCT`.
- [#1080](https://github.com/sqlfluff/sqlfluff/issues/1080) Add
SET SCHEMA and DROP SCHEMA support to ANSI dialect.

## [0.6.0a2] - 2021-05-27
### Changed
- Better exception handling for the simple parsing API (`sqlfluff.parse`)
which now raises an exception which holds all potential parsing issues
and prints nicely with more than one issue.

- [`L009`](https://docs.sqlfluff.com/en/stable/rules.html#sqlfluff.core.rules.Rule_L009) can now be enforced when `templater = dbt`.
- Parsing of `EXPLAIN`, `USE` statements.
- Parsing of `ALTER TABLE x RENAME TO y` syntax.
- Parsing of `ALTER SESSION` in snowflake.
- Parsing of numeric literals with exponents.
- Added rule codes to diff_cover output.
### Changed
- Fix `templater = dbt` L009 bug [#861](https://github.com/sqlfluff/sqlfluff/issues/861) where:
- `sqlfluff lint` would incorrectly always return `L009 | Files must end with a trailing newline.`
- `sqlfluff fix` would remove trailing newlines when `exclude_rules = L009`.
- Fix bug with BigQuery comparison operators.
- Fix recursion bug with L045.

- Output of `sqlfluff dialects` is now sorted.
- Handle disabled `dbt` models.
## [0.5.2] - 2021-04-11
### Changed
- Fix false positive in L045 when CTE used in WHERE clause ([#944](https://github.com/sqlfluff/sqlfluff/issues/944))
- Logging and readout now includes more detail and a notification of dbt compilation.
- Fix bug in L048 which flagged adjoining commas as failures.
- Fix bug in L019 with inline comments.
- Fix bug in L036 with multiple newlines.
- Skip disabled dbt models. ([#931](https://github.com/sqlfluff/sqlfluff/issues/931)).
- Support "USE" statement in ANSI ([#902](https://github.com/sqlfluff/sqlfluff/issues/902)).
- Parse explain statement ([#893](https://github.com/sqlfluff/sqlfluff/issues/893)).
## [0.5.1] - 2021-04-09
### Changed
- Parsing improvements around optional brackets.
- Better parsing of set operators (like `UNION`) and how they interact with
`ORDER BY` clauses.
- Support for comparison operators like `~`.
- Fix parsing of snowflake `SAMPLE` syntax.
- Fix recursion issues in L044.
- `SPACE` keyword now has no special meaning in the postgres dialect.
## [0.5.0] - 2021-04-05
### Added
- `pascal` (PascalCase) `capitalisation_policy` option for L014 (unquoted identifiers)
- `only_aliases` configuration option for L014 (unquoted identifiers)
- Dialects now have more advanced dependency options to allow less repetition
between related dialects. The methods `get_segment` and `get_grammar` can be
used on unexpanded grammars to access elements of the parent grammars.
The `copy` method on grammars can be used to copy with alterations.
- Rule L046 to line whitespace within jinja tags.
- Enable and Disable syntax for [ignoring violations from ranges of lines](https://docs.sqlfluff.com/en/latest/configuration.html#ignoring-line-ranges).
### Changed
- Renamed the BaseCrawler class to BaseRule. This is the base class for all
rules. This is a breaking change for any custom rules that have been added
via plugins or by forking the SQLFluff repo.
- Renamed `sqlfluff.rules()` to `sqlfluff.list_rules()` and `sqlfluff.dialects()`
to `sqlfluff.list_dialects()` due to naming conflicts with the now separate
`sqlfluff.dialects` module.
- Extracted dialect definitions from the `sqlfluff.core` module so that each
dialect is better isolated from each other. This also allows more focused
testing and the potential for dialect plugins in future. Dialects are now
only imported as needed at runtime. All dialects should now be accessed
using the selector methods in `sqlfluff.core.dialects` rather than importing
from `sqlfluff.dialects` directly.
- Add support for `ALTER USER` commands in Snowflake dialect.
- Added describe statement to ANSI dialect
- Renamed `capitalisation_policy` to `extended_capitalisation_policy` for L014
to reflect the fact that it now accepts more options (`pascal`) than regular
`capitalisation_policy` still used by L010 and others.
- Replaced `only_aliases` config with `unquoted_identifiers_policy` and added
it to rule L014 in addition to L029.
- Parse structure of `FROM` clauses to better represent nested joins and table
functions.
- Parse structure of expressions to avoid unnecessary nesting and overly
recursive method calls.
## [0.4.1] - 2021-02-25
### Added
- Initial architecture for rule plugins to allow custom rules. This
initial release should be considered _beta_ until the release of
0.5.0.
- Add tests for dbt 0.19.0.
- General increased parsing coverage.
- Added some missing Postgres syntax elements.
- Added some basic introspection API elements to output what dialects
and rules are available for use within the API.
### Changed
- Fix several Snowflake parsing bugs.
- Refactor from clause to handle flattens after joins.
- Fix .get_table_references() in Snowflake dialect.
- Macros defined within the .sqlfluff config will take precedence over the macros defined in the
path that is defined with config value `sqlfluff:templater:jinja:load_macros_from_path`.
- Fix Snowflake indent parsing.
- Fixed incorrect parsing of syntax-like elements in comments.
- Altered parsing of `NULL` keywords, so parse as Literals where
appropriate.
- Fixed bug in expression parsing leading to recursion errors.
## [0.4.0] - 2021-02-14
### Added
- Public API to enable people to import `sqlfluff` as a python module
and call `parse`, `lint` and `fix` within their own projects. See
[the docs](https://docs.sqlfluff.com/en/latest/api.html) for more
information. ([#501](https://github.com/sqlfluff/sqlfluff/pull/501))
- The ability to use `dbt` as a templating engine directly allowing
richer and more accurate linting around `dbt` macros (and packages
related to `dbt`). For more info see [the docs](https://docs.sqlfluff.com/en/latest/configuration.html#dbt-project-configuration). ([#508](https://github.com/sqlfluff/sqlfluff/pull/508))
- Support for modulo (`%`) operator. ([#447](https://github.com/sqlfluff/sqlfluff/pull/447))
- A limit in the internal fix routines to catch any infinite loops. ([#494](https://github.com/sqlfluff/sqlfluff/pull/494))
- Added the `.is_type()` method on segments to more intelligently
deal with type matching in rules when inheritance is at play.
- Added the ability for the user to add their own rules when interacting
with the `Linter` directly using `user_rules`.
- Added L034 'Fields should be stated before aggregates / window functions' per
[dbt coding convenventions](https://github.com/fishtown-analytics/corp/blob/master/dbt_coding_conventions.md#sql-style-guide.) ([#495](https://github.com/sqlfluff/sqlfluff/pull/495))
- Templating tags, such as `{{ variables }}`, `{# comments #}` and
`{% loops %}` (in jinja) now have placeholders in the parsed
structure. Rule L003 (indentation), also now respects these
placeholders so that their indentation is linted accordingly.
For loop or block tags, they also generate an `Indent` and
`Dedent` tag accordingly (which can be enabled or disabled)
with a configuration value so that indentation around these
functions can be linted accordingly. ([#541](https://github.com/sqlfluff/sqlfluff/pull/541))
- MyPy type linting into a large proportion of the core library. ([#526](https://github.com/sqlfluff/sqlfluff/pull/526), [#580](https://github.com/sqlfluff/sqlfluff/pull/580))
- Config values specific to a file can now be defined using a comment
line starting with `-- sqlfluff:`. ([#541](https://github.com/sqlfluff/sqlfluff/pull/541))
- Added documentation for `--noqa:` use in rules. ([#552](https://github.com/sqlfluff/sqlfluff/pull/552))
- Added `pre-commit` hooks for `lint` and `fix`. ([#576](https://github.com/sqlfluff/sqlfluff/pull/576))
- Added a fix routine for Rule L019 (comma placement). ([#575](https://github.com/sqlfluff/sqlfluff/pull/575))
- Added Rule L031 to enforce "avoid using alias in the `FROM`/`JOIN` clauses" from the `dbt` coding conventions. ([#473](https://github.com/sqlfluff/sqlfluff/pull/473), [#479](https://github.com/sqlfluff/sqlfluff/pull/479))
- Added Rule L032 to enforce "do not use `USING`" from the `dbt` coding conventions. ([#487](https://github.com/sqlfluff/sqlfluff/pull/487))
- Added Rule L033 to enforce "prefer `UNION ALL` to `UNION *`" from the `dbt` coding conventions. ([#489](https://github.com/sqlfluff/sqlfluff/pull/489))
- Added Rule L034 to enforce "fields should be stated before aggregate/window functions" from the `dbt` coding conventions. ([#495](https://github.com/sqlfluff/sqlfluff/pull/495))
- Added Rule L038 to forbid (or require) trailing commas in select clauses. ([#362](https://github.com/sqlfluff/sqlfluff/pull/752))
- Added Rule L039 to lint unnecessary whitespace between elements. ([#502](https://github.com/sqlfluff/sqlfluff/pull/753))
- Added a fix routine for L015. ([#732](https://github.com/sqlfluff/sqlfluff/pull/732))
- Added a fix routine for L025. ([#404](https://github.com/sqlfluff/sqlfluff/pull/741))
- Adopted the `black` coding style. ([#485](https://github.com/sqlfluff/sqlfluff/pull/485))
- Added validation and documentation for rule configuration options. ([#462](https://github.com/sqlfluff/sqlfluff/pull/462))
- Added documentation for which rules are fixable. ([#594](https://github.com/sqlfluff/sqlfluff/pull/594))
- Added `EPOCH` keyword for postgres dialect. ([#522](https://github.com/sqlfluff/sqlfluff/pull/522))
- Added column index identifier in snowflake dialect. ([#458](https://github.com/sqlfluff/sqlfluff/pull/458))
- Added `USE` statement to the snowflake dialect. ([#537](https://github.com/sqlfluff/sqlfluff/pull/537))
- Added `CODE_OF_CONDUCT` to the project. ([#471](https://github.com/sqlfluff/sqlfluff/pull/471))
- Added `ISNULL` and `NOTNULL` keywords to ansi dialect. ([#441](https://github.com/sqlfluff/sqlfluff/pull/441))
- Added support for python 3.9. ([#482](https://github.com/sqlfluff/sqlfluff/pull/482))
- Added `requirements_dev.txt` for local testing/linting. ([#500](https://github.com/sqlfluff/sqlfluff/pull/500))
- Added CLI option `--disregard-sqlfluffignores` to allow direct linting of files in the `.sqlfluffignore`. ([#486](https://github.com/sqlfluff/sqlfluff/pull/486))
- Added `dbt` `incremental` macro. ([#363](https://github.com/sqlfluff/sqlfluff/pull/363))
- Added links to cockroachlabs expression grammars in ansi dialect. ([#592](https://github.com/sqlfluff/sqlfluff/pull/592))
- Added favicon to the docs website. ([#589](https://github.com/sqlfluff/sqlfluff/pull/589))
- Added `CREATE FUNCTION` syntax for postgres and for bigquery. ([#325](https://github.com/sqlfluff/sqlfluff/pull/325))
- Added `CREATE INDEX` and `DROP INDEX` for mysql. ([#740](https://github.com/sqlfluff/sqlfluff/pull/748))
- Added `IGNORE NULLS`, `RESPECT NULLS`, `GENERATE_DATE_ARRAY` and
`GENERATE_TIMESTAMP_ARRAY` for bigquery. (
[#667](https://github.com/sqlfluff/sqlfluff/pull/727),
[#527](https://github.com/sqlfluff/sqlfluff/pull/726))
- Added `CREATE` and `CREATE ... CLONE` for snowflake. ([#539](https://github.com/sqlfluff/sqlfluff/pull/670))
- Added support for EXASOL. ([#684](https://github.com/sqlfluff/sqlfluff/pull/684))
### Changed
- Fixed parsing of semi-structured objects in the snowflake of dialects
with whitespace gaps. [#634](https://github.com/sqlfluff/sqlfluff/issues/635)
- Handle internal errors elegantly, reporting the stacktrace and the
error-surfacing file. [#632](https://github.com/sqlfluff/sqlfluff/pull/632)
- Improve message for when an automatic fix is not available for L004. [#633](https://github.com/sqlfluff/sqlfluff/issues/633)
- Linting errors raised on templated sections are now ignored by default
and added a configuration value to show them. ([#713](https://github.com/sqlfluff/sqlfluff/pull/745))
- Big refactor of logging internally. `Linter` is now decoupled from
logging so that it can be imported directly by subprojects without
needing to worry about weird output or without the log handing getting
in the way of your project. ([#460](https://github.com/sqlfluff/sqlfluff/pull/460))
- Linting errors in the final file are now reported with their position
in the source file rather than in the templated file. This means
when using sqlfluff as a plugabble library within an IDE, the
references match the file which is being edited. ([#541](https://github.com/sqlfluff/sqlfluff/pull/541))
- Created new Github Organisation (https://github.com/sqlfluff) and
migrated from https://github.com/alanmcruickshank/sqlfluff to
https://github.com/sqlfluff/sqlfluff. ([#444](https://github.com/sqlfluff/sqlfluff/issues/444))
- Changed the handling of `*` and `a.b.*` expressions to have their
own expressions. Any dependencies on this structure downstream
will be broken. This also fixes the linting of both kinds of expressions
with regard to L013 and L025. ([#454](https://github.com/sqlfluff/sqlfluff/pull/454))
- Refactor of L022 to handle poorly formatted CTEs better. ([#494](https://github.com/sqlfluff/sqlfluff/pull/494))
- Restriction of L017 to only fix when it would delete whitespace or
newlines. ([#598](https://github.com/sqlfluff/sqlfluff/pull/756))
- Added a configuration value to L016 to optionally ignore lines
containing only comments. ([#299](https://github.com/sqlfluff/sqlfluff/pull/751))
- Internally added an `EphemeralSegment` to aid with parsing efficiency
without altering the end structure of the query. ([#491](https://github.com/sqlfluff/sqlfluff/pull/491))
- Split `ObjectReference` into `ColumnReference` and `TableReference`
for more useful API access to the underlying structure. ([#504](https://github.com/sqlfluff/sqlfluff/pull/504))
- `KeywordSegment` and the new `SymbolSegment` both now inherit
from `_ProtoKeywordSegment` which allows symbols to match in a very
similar way to keywords without later appearing with the `type` of
`keyword`. ([#504](https://github.com/sqlfluff/sqlfluff/pull/504))
- Introduced the `Parser` class to parse a lexed query rather than
relying on users to instantiate a `FileSegment` directly. As a result
the `FileSegment` has been moved from the core parser directly into
the dialects. Users can refer to it via the `get_root_segment()`
method of a dialect. ([#510](https://github.com/sqlfluff/sqlfluff/pull/510))
- Several performance improvements through removing unused functionality,
sensible caching and optimising loops within functions. ([#526](https://github.com/sqlfluff/sqlfluff/pull/526))
- Split up rule tests into separate `yml` files. ([#553](https://github.com/sqlfluff/sqlfluff/pull/553))
- Allow escaped quotes in strings. ([#557](https://github.com/sqlfluff/sqlfluff/pull/557))
- Fixed `ESCAPE` parsing in `LIKE` clause. ([#566](https://github.com/sqlfluff/sqlfluff/pull/566))
- Fixed parsing of complex `BETWEEN` statements. ([#498](https://github.com/sqlfluff/sqlfluff/pull/498))
- Fixed BigQuery `EXCEPT` clause parsing. ([#472](https://github.com/sqlfluff/sqlfluff/pull/472))
- Fixed Rule L022 to respect leading comma configuration. ([#455](https://github.com/sqlfluff/sqlfluff/pull/455))
- Improved instructions on adding a virtual environment in the `README`. ([#457](https://github.com/sqlfluff/sqlfluff/pull/457))
- Improved documentation for passing CLI defaults in `.sqlfluff`. ([#452](https://github.com/sqlfluff/sqlfluff/pull/452))
- Fix bug with templated blocks + `capitalisation_policy = lower`. ([#477](https://github.com/sqlfluff/sqlfluff/pull/477))
- Fix array accessors in snowflake dialect. ([#442](https://github.com/sqlfluff/sqlfluff/pull/442))
- Color `logging` warnings red. ([#497](https://github.com/sqlfluff/sqlfluff/pull/497))
- Allow whitespace before a shorthand cast. ([#544](https://github.com/sqlfluff/sqlfluff/pull/544))
- Silenced warnings when fixing from stdin. ([#522](https://github.com/sqlfluff/sqlfluff/pull/522))
- Allow an underscore as the first char in a semi structured element key. ([#596](https://github.com/sqlfluff/sqlfluff/pull/596))
- Fix PostFunctionGrammar in the Snowflake dialect which was causing strange behaviour in L012. ([#619](https://github.com/sqlfluff/sqlfluff/pull/619/files))
- `Bracketed` segment now obtains its brackets directly from the dialect
using a set named `bracket_pairs`. This now enables better configuration
of brackets between dialects. ([#325](https://github.com/sqlfluff/sqlfluff/pull/325))
### Removed
- Dropped support for python 3.5. ([#482](https://github.com/sqlfluff/sqlfluff/pull/482))
- From the CLI, the `--no-safety` option has been removed, the default
is now that all enabled rules will be fixed. ([#583](https://github.com/sqlfluff/sqlfluff/pull/583))
- Removed `BaseSegment.grammar`, `BaseSegment._match_grammar()` and
`BaseSegment._parse_grammar()` instead preferring references directly
to `BaseSegment.match_grammar` and `BaseSegment.parse_grammar`. ([#509](https://github.com/sqlfluff/sqlfluff/pull/509))
- Removed `EmptySegmentGrammar` and replaced with better non-code handling
in the `FileSegment` itself. ([#509](https://github.com/sqlfluff/sqlfluff/pull/509))
- Remove the `ContainsOnly` grammar as it remained only as an anti-pattern. ([#509](https://github.com/sqlfluff/sqlfluff/pull/509))
- Removed the `expected_string()` functionality from grammars and segments ([#509](https://github.com/sqlfluff/sqlfluff/pull/509))
as it was poorly supported.
- Removed `BaseSegment.as_optional()` as now this functionality happens
mostly in grammars (including `Ref`). ([#509](https://github.com/sqlfluff/sqlfluff/pull/509))
- Removed `ColumnExpressionSegment` in favour of `ColumnReference`. ([#512](https://github.com/sqlfluff/sqlfluff/pull/512))
- Removed the `LambdaSegment` feature, instead replacing with an internal
to the grammar module called `NonCodeMatcher`. ([#512](https://github.com/sqlfluff/sqlfluff/pull/512))
- Case sensitivity as a feature for segment matching has been removed as
not required for existing dialects. ([#517](https://github.com/sqlfluff/sqlfluff/pull/517))
- Dependency on `difflib` or `cdifflib`, by relying on source mapping
instead to apply fixes. ([#541](https://github.com/sqlfluff/sqlfluff/pull/541))
## [0.3.6] - 2020-09-24
### Added
- `sqlfluff dialects` command to get a readout of available
dialects [+ associated docs].

- Functions in `GROUP BY`. Thanks [@flpezet](https://github.com/flpezet).
### Changed
- Deep bugfixes in the parser to handle simple matching better for a few
edge cases. Also added some logging deeper in the parser.
- Added in the `SelectableGrammar` and some related segments to make it
easier to refer to _select-like_ things in other grammars.
- Fixes to `CASE` statement parsing. Thanks [@azhard](https://github.com/azhard).
- Fix to snowflake `SAMPLE` implementation. Thanks [@rkm3](https://github.com/rkm3).
- Numerous docs fixes. Thanks [@SimonStJG](https://github.com/SimonStJG),
[@flpezet](https://github.com/flpezet), [@s-pace](https://github.com/s-pace),
[@nolanbconaway](https://github.com/nolanbconaway).
## [0.3.4] - 2020-05-13
### Changed
- Implementation of the bigquery `CREATE MODEL` syntax. Thanks [@barrywhart](https://github.com/barrywhart).
- Bugfixes for:
- Edge cases for L006
- False alarms on L025
- `ORDER BY x NULLS FIRST|LAST`
- `FOR` keyword in bigquery `SYSTEM_TIME` syntax.
## [0.3.3] - 2020-05-11
### Added
- Added the `--nofail` option to `parse` and `lint` commands to assist
rollout.
- Added the `--version` option to complement the `version` option already
available on the cli.
- Parsing for `ALTER TABLE`.
- Warning for unset dialects when getting parsing errors.
- Configurable line lengths for output.
## [0.3.2] - 2020-05-08
### Added
- Support for the Teradata dialect. Thanks [@Katzmann1983](https://github.com/Katzmann1983)!
- A much more detailed getting started guide in the docs.
- For the `parse` command, added the `--profiler` and `--bench` options
to help debugging performance issues.
- Support for the `do` command in the jinja templater.
- Proper parsing of the concatenate operator (`||`).
- Proper indent handling of closing brackets.
- Logging and benchmarking of parse performance as part of the CI pipeline.
- Parsing of object references with defaults like `my_db..my_table`.
- Support for the `INTERVAL '4 days'` style interval expression.
- Configurable trailing or leading comma linting.
- Configurable indentation for `JOIN` clauses.
- Rules now have their own logging interface to improve debugging ability.
- Snowflake and Postgres dialects.
- Support for a `.sqlfluffignore` file to ignore certain paths.
- More generic interfaces for managing keywords in dialects, including `set`
interfaces for managing and creating keywords and the `Ref.keyword()` method
to refer to them, and the ability to refer directly to keyword names in
most grammars using strings directly. Includes `SegmentGenerator` objects
to bind dialect objects at runtime from sets. Thanks [@Katzmann1983](https://github.com/Katzmann1983)!
- Rule `L029` for using unreserved keywords as variable names.
- The jinja templater now allows macros loaded from files, and the
hydration of variables ending in `_path` in the config files.
- JSON operators and the `DISTINCT ON ()` syntax for the postgres dialect.
### Changed
- Refactor of whitespace and non-code handling so that segments are
less greedy and default to not holding whitespace on ends. This allows
more consistent linting rule application.
- Change config file reading to _case-sensitive_ to support case
sensitivity in jinja templating.
- Non-string values (including lists) now function in the python
and jinja templating libraries.
- Validation of the match results of grammars has been reduced. In
production cases the validation will still be done, but only on
_parse_ and not on _match_.
- At low verbosities, python level logging is also reduced.
- Some matcher rules in the parser can now be classified as _simple_
which allows them to shortcut some of the matching routines.
- Yaml output now double quotes values with newlines or tab characters.
- Better handling on hanging and closing indents when linting rule L003.
- More capable handline of multi-line comments so that indentation
and line length parsing works. This involves some deep changes to the
lexer.
- Getting violations from the linter now automatically takes into account
of ignore rules and filters.
- Several bugfixes, including catching potential infinite regress during
fixing of files, if one fix would re-introduce a problem with another.
- Behaviour of the `Bracketed` grammar has been changed to treat its
content as a `Sequence` rather than a `OneOf`.
- Move to `SandboxedEnvironment` rather than `Environment` for jinja
templating for security.
- Improve reporting of templating issues, especially for the jinja templater
so that missing variables are rendered as blanks, but still reported as
templating violations.
## [0.3.1] - 2020-02-17
### Added
- Support for `a.b.*` on top of `a.*` in select target expressions.
## [0.3.0] - 2020-02-15
### Changed
- Deprecated python 2.7 and python 3.4 which are now both past
their maintenance horizon. The 0.2.x branch will remain available
for continued development for these versions.
- Rule L003 is now significantly smarter in linting indentation
with support for hanging indents and comparison to the most
recent line which doesn't have an error. The old (more simple)
functionality of directly checking whether an indent was a
multiple of a preset value has been removed.
- Fixed the "inconsistent" bug in L010. Thanks [@nolanbconaway](https://github.com/nolanbconaway).
- Updated logging of parsing and lexing errors to have more useful
error codes.
- Changed parsing of expressions to favour functions over identifiers
to [fix the expression bug](https://github.com/sqlfluff/sqlfluff/issues/96).
- Fixed the "inconsistent" bug in L010. Thanks [@nolanbconaway](https://github.com/nolanbconaway).
- Moved where the `SELECT` keyword is parsed within a select statement,
so that it belongs as part of the newly renamed `select_clause` (renamed
from previously `select_target_group`).
- Clarified handling of the `type` and `name` properties of the BaseSegment
class and its children. `name` should be specific to a particular kind
of segment, and `type` should express a wider group. Handling of the
`newline`, `whitespace` and `comma` segments has been updated so that
we use the `type` property for most use cases rather than `name`.
### Added
- _Meta segments_ for indicating where things can be present in the parsed
tree. This is mostly illustrated using the `Indent` and `Dedent` segments
used for indicating the position of theoretical indents in the structure.
Several helper functions have been added across the codebase to handle
this increase in the kinds of segments which might be encountered by
various grammars.
- Rule L016 has been added to lint long lines. In the `fix` phase of this
rule, there is enough logic to try and reconstruct a sensible place for
line breaks as re-flow the query. This will likely need further work
and may still encounter places where it doesn't fix all errors but should
be able to deal with the majority of simple cases.
- BigQuery dialect, initially just for appropriate quoting.
- Added parsing of DDL statements such as `COMMIT`, `DROP`, `GRANT`, `REVOKE`
and `ROLLBACK`. Thanks [@barrywhart](https://github.com/barrywhart).
- `--format` option to the `parse` command that allows a yaml output. This
is mostly to make test writing easier in the development process but
might also be useful for other things.
- Parsing of set operations like `UNION`.
- Support for the `diff-cover` tool. Thanks [@barrywhart](https://github.com/barrywhart).
- Enabled the `fix` command while using `stdin`. Thanks [@nolanbconaway](https://github.com/nolanbconaway).
- Rule to detect incorrect use of `DISTINCT`. Thanks [@barrywhart](https://github.com/barrywhart).
- Security fixes from DeepCover. Thanks [@sanketsaurav](https://github.com/sanketsaurav).
- Automatic fix testing, to help support the newer more complicated rules.
- Interval literals
- Support for the `source` macro from dbt. Thanks [@Dandandan](https://github.com/Dandandan)
- Support for functions with spaces between the function name and the brackets
and a linting rule `L017` to catch this.
- Efficiency cache for faster pruning of the parse tree.
- Parsing of array notation as using in BigQuery and Postgres.
- Enable the `ignore` parameter on linting and fixing commands to ignore
particular kinds of violations.
## [0.2.4] - 2019-12-06
### Added
- A `--code-only` option to the `parse` command to spit out a more
simplified output with only the code elements.
- Rules can now optionally override the description of the violation
and pass that back via the `LintingResult`.
### Changed
- Bugfix, correct missing files in `setup.py` `install_requires` section.
- Better parsing of the _not equal_ operator.
- Added more exclusions to identifier reserved words to fix cross joins.
- At verbosity levels 2 or above, the root config is printed and then any
diffs to that for specific files are also printed.
- Linting and parsing of directories now reports files in alphabetical
order. Thanks [@barrywhart](https://github.com/barrywhart).
- Better python 2.7 stability. Thanks [@barrywhart](https://github.com/barrywhart).
- Fixing parsing of `IN`/`NOT IN` and `IS`/`IS NOT`.
## [0.2.3] - 2019-12-02
### Changed
- Bugfix, default config not included.
## [0.2.2] - 2019-12-02
### Changed
- Tweak rule L005 to report more sensibly with newlines.
- Rework testing of rules to be more modular.
- Fix a config file bug if no root config file was present for some
values. Thanks [@barrywhart](https://github.com/barrywhart).
- Lexing rules are now part of the dialect rather than a
global so that they can be overridden by other dialects
when we get to that stage.
## [0.2.0] - 2019-12-01
### Added
- Templating support (jinja2, python or raw).
- Variables + Macros.
- The `fix` command is also sensitive to fixing over templates
and will skip certain fixes if it feels that it's conflicted.
- Config file support, including specifying context for the templater.
- Documentation via Sphinx and readthedocs.
- Including a guide on the role of SQL in the real world.
Assisted by [@barrywhart](https://github.com/barrywhart).
- Documentation LINTING (given we're a linting project) introduced in CI.
- Reimplemented L006 & L007 which lint whitespace around operators.
- Ability to configure rule behaviour directly from the config file.
- Implemented L010 to lint capitalisation of keywords.
- Allow casting in the parser using the `::` operator.
- Implemented `GROUP BY`and `LIMIT`.
- Added `ORDER BY` using indexes and expressions.
- Added parsing of `CASE` statements.
- Support for window/aggregate functions.
- Added linting and parsing of alias expressions.
### Changed
- Fixed a bug which could cause potential infinite recursion in configuration
- Changed how negative literals are handled, so that they're now a compound segment
rather than being identified at the lexing stage. This is to allow the parser
to resolve the potential ambiguity.
- Restructure of rule definitions to be more streamlined and also enable
autodocumentation. This includes a more complete `RuleSet` class which now
holds the filtering code.
- Corrected logging in fix mode not to duplicate the reporting of errors.
- Now allows insert statements with a nested `with` clause.
- Fixed verbose logging during parsing.
- Allow the `Bracketed` grammar to optionally match empty brackets using
the optional keyword.
## [0.1.5] - 2019-11-11
### Added
- Python 3.8 Support!
### Changed
- Moved some of the responsibility for formatted logging into the linter to mean that we can
log progressively in large directories.
- Fixed a bug in the grammar where one of the return values was messed up.
## [0.1.4] - 2019-11-10
### Added
- Added a `--exclude-rules` argument to most of the commands to allow rule users
to exclude specific subset of rules, by [@sumitkumar1209](https://github.com/sumitkumar1209)
- Added lexing for `!=`, `~` and `::`.
- Added a new common segment: `LambdaSegment` which allows matching based on arbitrary
functions which can be applied to segments.
- Recursive Expressions for both arithmetic and functions, based heavily off the grammar
provided by the guys at [CockroachDB](https://www.cockroachlabs.com/docs/stable/sql-grammar.html#select_stmt).
- An `Anything` grammar, useful in matching rather than in parsing to match anything.
### Changed
- Complete rewrite of the bracket counting functions, using some centralised class methods
on the `BaseGrammar` class to support common matching features across multiple grammars.
In particular this affects the `Delimited` grammar which is now _much simpler_ but does
also require _slightly_ more liberal use of terminators to match effectively.
- Rather than passing around multiple variables during parsing and matching, there is now
a `ParseContext` object which contains things like the dialect and various depths. This
simplifies the parsing and matching code significantly.
- Bracket referencing is now done from the dialect directly, rather than in individual
Grammars (except the `Bracketed` grammar, which still implements it directly). This
takes out some originally duplicated code.
- Corrected the parsing of ordering keywords in and `ORDER BY` clause.
### Removed
- Removed the `bracket_sensitive_forward_match` method from the `BaseGrammar`. It was ugly
and not flexible enough. It's been replaced by a suite of methods as described above.
## [0.1.3] - 2019-10-30
### Changed
- Tweak to the L001 rule so that it doesn't crash the whole thing.
## [0.1.2] - 2019-10-30
### Changed
- Fixed the errors raised by the lexer.
## [0.1.1] - 2019-10-30
### Changed
- Fixed which modules from sqlfluff are installed in the setup.py. This affects
the `version` command.
## [0.1.0] - 2019-10-29
### Changed
- _Big Rewrite - some loss in functionality might be apparent compared
to pre-0.1.0. Please submit any major problems as issues on github_
- Changed unicode handling for better escape codes in python 2.
Thanks [@mrshu](https://github.com/mrshu)
- BIG rewrite of the parser, completely new architecture. This introduces
breaking changes and some loss of functionality while we catch up.
- In particular, matches now return partial matches to speed up parsing.
- The `Delimited` matcher has had a significant re-write with a major
speedup and broken the dependency on `Sequence`.
- Rewrite of `StartsWith` and `Sequence` to use partial matches properly.
- Different treatment of numeric literals.
- Both `Bracketed` and `Delimited` respect bracket counting.
- MASSIVE rewrite of `Bracketed`.
- Grammars now have timers.
- Joins properly parsing,
- Rewrite of logging to selectively output commands at different levels
of verbosity. This uses the `verbosity_logger` method.
- Added a command line `sqlfluff parse` option which runs just the parsing step
of the process to better understand how a file is being parsed. This also
has options to configure how deep we recurse.
- Complete Re-write of the rules section, implementing new `crawlers` which
implement the linting rules. Now with inbuilt fixers in them.
- Old rules removed and re implemented so we now have parity with the old rule sets.
- Moved to using Ref mostly within the core grammar so that we can have recursion.
- Used recursion to do a first implementation of arithmetic parsing. Including a test for it.
- Moved the main grammar into a separate dialect and renamed source and test files accordingly.
- Moved to file-based tests for the ansi dialect to make it easier to test using the tool directly.
- As part of file tests - expected outcomes are now encoded in yaml to make it easier to write new tests.
- Vastly improved readability and debugging potential of the \_match logging.
- Added support for windows line endings in the lexer.
## [0.0.7] - 2018-11-19
### Added
- Added a `sqlfluff fix` as a command to implement auto-fixing of linting
errors. For now only `L001` is implemented as a rule that can fix things.
- Added a `rules` command to introspect the available rules.
- Updated the cli table function to use the `testwrap` library and also
deal a lot better with longer values.
- Added a `--rules` argument to most of the commands to allow rule users
to focus their search on a specific subset of rules.
### Changed
- Refactor the cli tests to use the click CliRunner. Much faster
## [0.0.6] - 2018-11-15
### Added
- Number matching
### Changed
- Fixed operator parsing and linting (including allowing the exception of `(*)`)
## [0.0.5] - 2018-11-15
### Added
- Much better documentation including the DOCS.md
### Changed
- Fixed comma parsing and linting
## [0.0.4] - 2018-11-14
### Added
- Added operator regexes
- Added a priority for matchers to resolve some ambiguity
- Added tests for operator regexes
- Added ability to initialise the memory in rules
## [0.0.3] - 2018-11-14
### Added
- Refactor of rules to allow rules with memory
- Adding comma linting rules (correcting the single character matchers)
- Adding mixed indentation linting rules
- Integration with CircleCI, CodeCov and lots of badges
### Changed
- Changed import of version information to fix bug with importing config.ini
- Added basic violations/file reporting for some verbosities
- Refactor of rules to simplify definition
- Refactor of color cli output to make it more reusable
## [0.0.2] - 2018-11-09
