+## dbt-core 1.1.0 - April 28, 2022
+### Breaking Changes
+- **Relevant to maintainers of adapter plugins _only_:** The abstractmethods `get_response` and `execute` now only return a `connection.AdapterReponse` in type hints. (Previously, they could return a string.) We encourage you to update your methods to return an object of class `AdapterResponse`, or implement a subclass specific to your adapter
+ ([#4499](https://github.com/dbt-labs/dbt-core/issues/4499), [#4869](https://github.com/dbt-labs/dbt-core/pull/4869))
+- For adapter plugin maintainers only: Internal adapter methods `set_relations_cache` + `_relations_cache_for_schemas` each take an additional argument, for use with experimental `CACHE_SELECTED_ONLY` config ([#4688](https://github.com/dbt-labs/dbt-core/issues/4688), [#4860](https://github.com/dbt-labs/dbt-core/pull/4860))
+### Features
+- Change behaviour of `non_null` test so that it only `select`s all columns if `--store-failures` is enabled. ([#4769](https://github.com/dbt-labs/dbt-core/issues/4769), [#4777](https://github.com/dbt-labs/dbt-core/pull/4777))
+- Testing framework for dbt adapter testing ([#4730](https://github.com/dbt-labs/dbt-core/issues/4730), [#4846](https://github.com/dbt-labs/dbt-core/pull/4846))
+- Allow unique key to take a list implementation for postgres/redshift ([#4738](https://github.com/dbt-labs/dbt-core/issues/4738), [#4858](https://github.com/dbt-labs/dbt-core/pull/4858))
+- Add `--cache_selected_only` flag to cache schema object of selected models only. ([#4688](https://github.com/dbt-labs/dbt-core/issues/4688), [#4860](https://github.com/dbt-labs/dbt-core/pull/4860))
+- Support custom names for generic tests ([#3348](https://github.com/dbt-labs/dbt-core/issues/3348), [#4898](https://github.com/dbt-labs/dbt-core/pull/4898))

+- Enable dbt jobs to run downstream models based on fresher sources. Compare the source freshness results between previous and current state. If any source is fresher and/or new in current vs. previous state, dbt will run and test the downstream models in scope. Example command: `dbt build --select source_status:fresher+`  ([#4050](https://github.com/dbt-labs/dbt-core/issues/4050), [#4256](https://github.com/dbt-labs/dbt-core/pull/4256))

+# CHANGELOG Automation
+
+We use [changie](https://changie.dev/) to automate `CHANGELOG` generation.  For installation and format/command specifics, see the documentation.
+
+### Quick Tour
+
+- All new change entries get generated under `/.changes/unreleased` as a yaml file
+- `header.tpl.md` contains the contents of the entire CHANGELOG file
+- `0.0.0.md` contains the contents of the footer for the entire CHANGELOG file.  changie looks to be in the process of supporting a footer file the same as it supports a header file.  Switch to that when available.  For now, the 0.0.0 in the file name forces it to the bottom of the changelog no matter what version we are releasing.
+- `.changie.yaml` contains the fields in a change, the format of a single change, as well as the format of the Contributors section for each version.
+
+### Workflow
+
+#### Daily workflow
+Almost every code change we make associated with an issue will require a `CHANGELOG` entry.  After you have created the PR in GitHub, run `changie new` and follow the command prompts to generate a yaml file with your change details.  This only needs to be done once per PR.
+
+The `changie new` command will ensure correct file format and file name.  There is a one to one mapping of issues to changes.  Multiple issues cannot be lumped into a single entry. If you make a mistake, the yaml file may be directly modified and saved as long as the format is preserved.
+
+Note: If your PR has been cleared by the Core Team as not needing a changelog entry, the `Skip Changelog` label may be put on the PR to bypass the GitHub action that blacks PRs from being merged when they are missing a `CHANGELOG` entry.
+
+#### Prerelease Workflow
+These commands batch up changes in `/.changes/unreleased` to be included in this prerelease and move those files to a directory named for the release version.  The `--move-dir` will be created if it does not exist and is created in `/.changes`.
+
+```
+changie batch <version>  --move-dir '<version>' --prerelease 'rc1'
+changie merge
+```
+
+Example
+```
+changie batch 1.0.5  --move-dir '1.0.5' --prerelease 'rc1'
+changie merge
+```
+
+#### Final Release Workflow
+These commands batch up changes in `/.changes/unreleased` as well as `/.changes/<version>` to be included in this final release and delete all prereleases.  This rolls all prereleases up into a single final release.  All `yaml` files in `/unreleased` and `<version>` will be deleted at this point.
+
+```
+changie batch <version>  --include '<version>' --remove-prereleases
+changie merge
+```
+
+Example
+```
+changie batch 1.0.5  --include '1.0.5' --remove-prereleases
+changie merge
+```
+
+### A Note on Manual Edits & Gotchas
+- Changie generates markdown files in the `.changes` directory that are parsed together with the `changie merge` command.  Every time `changie merge` is run, it regenerates the entire file.  For this reason, any changes made directly to `CHANGELOG.md` will be overwritten on the next run of `changie merge`.
+- If changes need to be made to the `CHANGELOG.md`, make the changes to the relevant `<version>.md` file located in the `/.changes` directory.  You will then run `changie merge` to regenerate the `CHANGELOG.MD`.
+- Do not run `changie batch` again on released versions.  Our final release workflow deletes all of the yaml files associated with individual changes.  If for some reason modifications to the `CHANGELOG.md` are required after we've generated the final release `CHANGELOG.md`, the modifications need to be done manually to the `<version>.md` file in the `/.changes` directory.
+- changie can modify, create and delete files depending on the command you run.  This is expected.  Be sure to commit everything that has been modified and deleted.

-# **what?**
-# This workflow runs all integration tests for supported OS
-# and python versions and core adapters. If triggered by PR,
-# the workflow will only run tests for adapters related
-# to code changes. Use the `test all` and `test ${adapter}`
-# label to run all or additional tests. Use `ok to test`
-# label to mark PRs from forked repositories that are safe
-# to run integration tests for. Requires secrets to run
-# against different warehouses.
-
-# **why?**
-# This checks the functionality of dbt from a user's perspective
-# and attempts to catch functional regressions.
-
-# **when?**
-# This workflow will run on every push to a protected branch
-# and when manually triggered. It will also run for all PRs, including
-# PRs from forks. The workflow will be skipped until there is a label

+# **what?**
+# Release workflow provides the following steps:
+# - checkout the given commit;
+# - validate version in sources and changelog file for given version;
+# - bump the version and generate a changelog if needed;
+# - merge all changes to the target branch if needed;
+# - run unit and integration tests against given commit;
+# - build and package that SHA;
+# - release it to GitHub and PyPI with that specific build;
+#
+# **why?**
+# Ensure an automated and tested release process
+#
+# **when?**
+# This workflow can be run manually on demand or can be called by other workflows

 ### Invoking dbt
 
-There are two supported ways of invoking dbt: from the command line and using an RPC server.
-
-The "tasks" map to top-level dbt commands. So `dbt run` => task.run.RunTask, etc. Some are more like abstract base classes (GraphRunnableTask, for example) but all the concrete types outside of task/rpc should map to tasks. Currently one executes at a time. The tasks kick off their “Runners” and those do execute in parallel. The parallelism is managed via a thread pool, in GraphRunnableTask.

 ## Adapters
 
-dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. The four core adapters that are in the main repository, contained within the [`plugins`](plugins) subdirectory, are: Postgres Redshift, Snowflake and BigQuery. Other warehouses use adapter plugins defined in separate repositories (e.g. [dbt-spark](https://github.com/dbt-labs/dbt-spark), [dbt-presto](https://github.com/dbt-labs/dbt-presto)).
+dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. For testing and development purposes, the dbt-postgres plugin lives alongside the dbt-core codebase, in the [`plugins`](plugins) subdirectory. Like other adapter plugins, it is a self-contained codebase and package that builds on top of dbt-core.
 
-Each adapter is a mix of python, Jinja2, and SQL. The adapter code also makes heavy use of Jinja2 to wrap modular chunks of SQL functionality, define default implementations, and allow plugins to override it.

 ### Defining the problem
 
-If you have an idea for a new feature or if you've discovered a bug in `dbt`, the first step is to open an issue. Please check the list of [open issues](https://github.com/dbt-labs/dbt/issues) before creating a new one. If you find a relevant issue, please add a comment to the open issue instead of creating a new one. There are hundreds of open issues in this repository and it can be hard to know where to look for a relevant open issue. **The `dbt` maintainers are always happy to point contributors in the right direction**, so please err on the side of documenting your idea in a new issue if you are unsure where a problem statement belongs.

 > **Note:** All community-contributed Pull Requests _must_ be associated with an open issue. If you submit a Pull Request that does not pertain to an open issue, you will be asked to create an issue describing the problem before the Pull Request can be reviewed.
 
 ### Discussing the idea
 
-After you open an issue, a `dbt` maintainer will follow up by commenting on your issue (usually within 1-3 days) to explore your idea further and advise on how to implement the suggested changes. In many cases, community members will chime in with their own thoughts on the problem statement. If you as the issue creator are interested in submitting a Pull Request to address the issue, you should indicate this in the body of the issue. The `dbt` maintainers are _always_ happy to help contributors with the implementation of fixes and features, so please also indicate if there's anything you're unsure about or could use guidance around in the issue.

-The `dbt` maintainers will add a `good first issue` label if an issue is suitable for a first-time contributor. This label often means that the required code change is small, limited to one database adapter, or a net-new addition that does not impact existing functionality.

 Here's a good workflow:
 - Comment on the open issue, expressing your interest in contributing the required code change
 - Outline your planned implementation. If you want help getting started, ask!
-- Follow the steps outlined below to develop locally. Once you have opened a PR, one of the `dbt` maintainers will work with you to review your code.
-- Add a test! Tests are crucial for both fixes and new features alike. We want to make sure that code works as intended, and that it avoids any bugs  previously encountered. Currently, the best resource for understanding `dbt`'s [unit](test/unit) and [integration](test/integration) tests is the tests themselves. One of the maintainers can help by pointing out relevant examples.

In other cases, the issue might describe functionality that the `dbt` maintainers are unwilling or unable to incorporate into the `dbt` codebase. When it is determined that an open issue describes functionality that will not translate to a code change in the `dbt` repository, the issue will be tagged with the `wontfix` label (see below) and closed.

 ### Using issue labels
 
-The `dbt` maintainers use labels to categorize open issues. Some labels indicate the databases impacted by the issue, while others describe the domain in the `dbt` codebase germane to the discussion. While most of these labels are self-explanatory (eg. `snowflake` or `bigquery`), there are others that are worth describing.

 #### Branching Strategy
 
-`dbt` has three types of branches:
+`dbt-core` has three types of branches:
 
-- **Trunks** are where active development of the next release takes place. There is one trunk named `develop` at the time of writing this, and will be the default branch of the repository.
-- **Release Branches** track a specific, not yet complete release of `dbt`. Each minor version release has a corresponding release branch. For example, the `0.11.x` series of releases has a branch called `0.11.latest`. This allows us to release new patch versions under `0.11` without necessarily needing to pull them into the latest version of `dbt`.

+- **Trunks** are where active development of the next release takes place. There is one trunk named `main` at the time of writing this, and will be the default branch of the repository.

 Configure your [profile](https://docs.getdbt.com/docs/configure-your-profile) as necessary to connect to your target databases. It may be a good idea to add a new profile pointing to a local postgres instance, or a specific test sandbox within your data warehouse if appropriate.
 
 ## Testing
 
-Getting the `dbt` integration tests set up in your local environment will be very helpful as you start to make changes to your local version of `dbt`. The section that follows outlines some helpful tips for setting up the test environment.
+Getting the `dbt-core` integration tests set up in your local environment will be very helpful as you start to make changes to your local version of `dbt-core`. The section that follows outlines some helpful tips for setting up the test environment.
 
-Since `dbt` works with a number of different databases, you will need to supply credentials for one or more of these databases in your test environment. Most organizations don't have access to each of a BigQuery, Redshift, Snowflake, and Postgres database, so it's likely that you will be unable to run every integration test locally. Fortunately, dbt Labs provides a CI environment with access to sandboxed Redshift, Snowflake, BigQuery, and Postgres databases. See the section on [_Submitting a Pull Request_](#submitting-a-pull-request) below for more information on this CI setup.
+Although `dbt-core` works with a number of different databases, you won't need to supply credentials for every one of these databases in your test environment. Instead you can test all dbt-core code changes with Python and Postgres.
 
 ### Initial setup
 
-We recommend starting with `dbt`'s Postgres tests. These tests cover most of the functionality in `dbt`, are the fastest to run, and are the easiest to set up. To run the Postgres integration tests, you'll have to do one extra step of setting up the test database:

-`dbt` uses test credentials specified in a `test.env` file in the root of the repository for non-Postgres databases. This `test.env` file is git-ignored, but please be _extra_ careful to never check in credentials or other sensitive information when developing against `dbt`. To create your `test.env` file, copy the provided sample file, then supply your relevant credentials. This step is only required to use non-Postgres databases.

+# Contexts and Jinja rendering
+
+Contexts are used for Jinja rendering. They include context methods, executable macros, and various settings that are available in Jinja.
+
+The most common entrypoint to Jinja rendering in dbt is a method named `get_rendered`, which takes two arguments: templated code (string), and a context used to render it (dictionary). 
+
+The context is the bundle of information that is in "scope" when rendering Jinja-templated code. For instance, imagine a simple Jinja template:
+```
+{% set new_value = some_macro(some_variable) %}
+```
+Both `some_macro()` and `some_variable` must be defined in that context. Otherwise, it will raise an error when rendering.
+
+Different contexts are used in different places because we allow access to different methods and data in different places. Executable SQL, for example, includes all available macros and the model being run. The variables and macros in scope for Jinja defined in yaml files is much more limited.
+
+### Implementation
+
+The context that is passed to Jinja is always in a dictionary format, not an actual class, so a `to_dict()` is executed on a context class before it is used for rendering.
+
+Each context has a `generate_<name>_context` function to create the context. `ProviderContext` subclasses have different generate functions for parsing and for execution, so that certain functions (notably `ref`, `source`, and `config`) can return different results
+
+### Hierarchy
+
+All contexts inherit from the `BaseContext`, which includes "pure" methods (e.g. `tojson`), `env_var()`, and `var()` (but only CLI values, passed via `--vars`).
+
+Methods available in parent contexts are also available in child contexts.
+
+```
+   BaseContext -- core/dbt/context/base.py
+     SecretContext -- core/dbt/context/secret.py
+     TargetContext -- core/dbt/context/target.py

+             TestContext -- core/dbt/context/provider.py
+```
+
+### Contexts for configuration
+
+Contexts for rendering "special" `.yml` (configuration) files:
+- `SecretContext`: Supports "secret" env vars, which are prefixed with `DBT_ENV_SECRET_`. Used for rendering in `profiles.yml` and `packages.yml` ONLY. Secrets defined elsewhere will raise explicit errors.
+- `TargetContext`: The same as `Base`, plus `target` (connection profile). Used most notably in `dbt_project.yml` and `selectors.yml`.
+
+Contexts for other `.yml` files in the project:
+- `SchemaYamlContext`: Supports `vars` declared on the CLI and in `dbt_project.yml`. Does not support custom macros, beyond `var()` + `env_var()` methods. Used for all `.yml` files, to define properties and configuration.
+- `DocsRuntimeContext`: Standard `.yml` file context, plus `doc()` method (with all `docs` blocks in scope). Used to resolve `description` properties.
