 ### 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.

-## dbt-core 1.0.0rc1 (November 10, 2021)
-
-### Breaking changes
-- Replace `greedy` flag/property for test selection with `indirect_selection: eager/cautious` flag/property. Set to `eager` by default. **Note:** This reverts test selection to its pre-v0.20 behavior by default. `dbt test -s my_model` _will_ select multi-parent tests, such as `relationships`, that depend on unselected resources. To achieve the behavior change in v0.20 + v0.21, set `--indirect-selection=cautious` on the CLI or `indirect_selection: cautious` in yaml selectors. ([#4082](https://github.com/dbt-labs/dbt-core/issues/4082), [#4104](https://github.com/dbt-labs/dbt-core/pull/4104))
-- In v1.0.0, **`pip install dbt` will raise an explicit error.** Instead, please use `pip install dbt-<adapter>` (to use dbt with that database adapter), or `pip install dbt-core` (for core functionality). For parity with the previous behavior of `pip install dbt`, you can use: `pip install dbt-core dbt-postgres dbt-redshift dbt-snowflake dbt-bigquery` ([#4100](https://github.com/dbt-labs/dbt-core/issues/4100), [#4133](https://github.com/dbt-labs/dbt-core/pull/4133))
-- Reorganize the `global_project` (macros) into smaller files with clearer names. Remove unused global macros: `column_list`, `column_list_for_create_table`, `incremental_upsert` ([#4154](https://github.com/dbt-labs/dbt-core/pull/4154))
-- Introduce structured event interface, and begin conversion of all legacy logging ([#3359](https://github.com/dbt-labs/dbt-core/issues/3359), [#4055](https://github.com/dbt-labs/dbt-core/pull/4055))
-    - **This is a breaking change for adapter plugins, requiring a very simple migration.** See [`events` module README](core/dbt/events/README.md#adapter-maintainers) for details.
-    - If you maintain another kind of dbt-core plugin that makes heavy use of legacy logging, and you need time to cut over to the new event interface, you can re-enable the legacy logger via an environment variable shim, `DBT_ENABLE_LEGACY_LOGGER=True`. Be advised that we will remove this capability in a future version of dbt-core.
-
-### Features
-- Allow nullable `error_after` in source freshness ([#3874](https://github.com/dbt-labs/dbt-core/issues/3874), [#3955](https://github.com/dbt-labs/dbt-core/pull/3955))
-- Add `metrics` nodes ([#4071](https://github.com/dbt-labs/dbt-core/issues/4071), [#4235](https://github.com/dbt-labs/dbt-core/pull/4235))
-- Add support for `dbt init <project_name>`, and support for `skip_profile_setup` argument (`dbt init -s`) ([#4156](https://github.com/dbt-labs/dbt-core/issues/4156), [#4249](https://github.com/dbt-labs/dbt-core/pull/4249))

-- Account for test rename: `schema` &rarr; `generic`, `data` &rarr;` singular`. Use `test_metadata` instead of `schema`/`data` tags to differentiate ([docs#216](https://github.com/dbt-labs/dbt-docs/issues/216), [docs#222](https://github.com/dbt-labs/dbt-docs/pull/222))
-- Add `metrics` ([core#216](https://github.com/dbt-labs/dbt-core/issues/4235), [docs#223](https://github.com/dbt-labs/dbt-docs/pull/223))
-
-### Under the hood
-- Bump artifact schema versions for 1.0.0: manifest v4, run results v4, sources v3. Notable changes: added `metrics` nodes; schema test + data test nodes are renamed to generic test + singular test nodes; freshness threshold default values ([#4191](https://github.com/dbt-labs/dbt-core/pull/4191))
-- Speed up node selection by skipping `incorporate_indirect_nodes` if not needed ([#4213](https://github.com/dbt-labs/dbt-core/issues/4213), [#4214](https://github.com/dbt-labs/dbt-core/issues/4214))
-- When `on_schema_change` is set, pass common columns as `dest_columns` in incremental merge macros ([#4144](https://github.com/dbt-labs/dbt-core/issues/4144), [#4170](https://github.com/dbt-labs/dbt-core/pull/4170))
-- Clear adapters before registering in `lib` module config generation ([#4218](https://github.com/dbt-labs/dbt-core/pull/4218))
-- Remove official support for python 3.6, which is reaching end of life on December 23, 2021 ([#4134](https://github.com/dbt-labs/dbt-core/issues/4134), [#4223](https://github.com/dbt-labs/dbt-core/pull/4223))

-## dbt-core 1.0.0b1 (October 11, 2021)
-
-### Breaking changes
-
-- The two type of test definitions are now "singular" and "generic" (instead of "data" and "schema", respectively). The `test_type:` selection method accepts `test_type:singular` and `test_type:generic`. (It will also accept `test_type:schema` and `test_type:data` for backwards compatibility) ([#3234](https://github.com/dbt-labs/dbt-core/issues/3234), [#3880](https://github.com/dbt-labs/dbt-core/pull/3880)). **Not backwards compatible:** The `--data` and `--schema` flags to `dbt test` are no longer supported, and tests no longer have the tags `'data'` and `'schema'` automatically applied.
-- Deprecated the use of the `packages` arg `adapter.dispatch` in favor of the `macro_namespace` arg. ([#3895](https://github.com/dbt-labs/dbt-core/issues/3895))

-- Enact deprecation to remove the `release` arg from the `execute_macro` method. ([#3900](https://github.com/dbt-labs/dbt-core/issues/3900))
-- Enact deprecation for default quoting to be True.  Override for the `dbt-snowflake` adapter so it stays `False`. ([#3898](https://github.com/dbt-labs/dbt-core/issues/3898))
-- Enact deprecation for object used as dictionaries when they should be dataclasses. Replace deprecation warning with an exception for the dunder methods of `__iter__` and `__len__` for all superclasses of FakeAPIObject. ([#3897](https://github.com/dbt-labs/dbt-core/issues/3897))
-- Enact deprecation for `adapter-macro` and replace deprecation warning with an exception. ([#3901](https://github.com/dbt-labs/dbt-core/issues/3901))
-- Add warning when trying to put a node under the wrong key.  ie. A seed under models in a `schema.yml` file. ([#3899](https://github.com/dbt-labs/dbt-core/issues/3899))
-- Plugins for `redshift`, `snowflake`, and `bigquery` have moved to separate repos: [`dbt-redshift`](https://github.com/dbt-labs/dbt-redshift), [`dbt-snowflake`](https://github.com/dbt-labs/dbt-snowflake), [`dbt-bigquery`](https://github.com/dbt-labs/dbt-bigquery)
-- Change the default dbt packages installation directory to `dbt_packages` from `dbt_modules`.  Also rename `module-path` to `packages-install-path` to allow default overrides of package install directory.  Deprecation warning added for projects using the old `dbt_modules` name without specifying a `packages-install-path`.  ([#3523](https://github.com/dbt-labs/dbt-core/issues/3523))
-- Update the default project paths to be `analysis-paths = ['analyses']` and `test-paths = ['tests]`. Also have starter project set `analysis-paths: ['analyses']` from now on.  ([#2659](https://github.com/dbt-labs/dbt-core/issues/2659))

 ## About this document
 
-This document is a guide intended for folks interested in contributing to `dbt-core`. Below, we document the process by which members of the community should create issues and submit pull requests (PRs) in this repository. It is not intended as a guide for using `dbt-core`, and it assumes a certain level of familiarity with Python concepts such as virtualenvs, `pip`, python modules, filesystems, and so on. This guide assumes you are using macOS or Linux and are comfortable with the command line.
+There are many ways to contribute to the ongoing development of `dbt-core`, such as by participating in discussions and issues. We encourage you to first read our higher-level document: ["Expectations for Open Source Contributors"](https://docs.getdbt.com/docs/contributing/oss-expectations).
 
-If you're new to python development or contributing to open-source software, we encourage you to read this document from start to finish. If you get stuck, drop us a line in the `#dbt-core-development` channel on [slack](https://community.getdbt.com).
+The rest of this document serves as a more granular guide for contributing code changes to `dbt-core` (this repository). It is not intended as a guide for using `dbt-core`, and some pieces assume a level of familiarity with Python development (virtualenvs, `pip`, etc). Specific code snippets in this guide assume you are using macOS or Linux and are comfortable with the command line.
 
-#### Adapters

+### Notes
 
-### Signing the CLA
-
-Please note that all contributors to `dbt-core` must sign the [Contributor License Agreement](https://docs.getdbt.com/docs/contributor-license-agreements) to have their Pull Request merged into the `dbt-core` codebase. If you are unable to sign the CLA, then the `dbt-core` maintainers will unfortunately be unable to merge your Pull Request. You are, however, welcome to open issues and comment on existing ones.
-
-## Proposing a change
-
-`dbt-core` is Apache 2.0-licensed open source software. `dbt-core` is what it is today because community members like you have opened issues, provided feedback, and contributed to the knowledge loop for the entire communtiy. Whether you are a seasoned open source contributor or a first-time committer, we welcome and encourage you to contribute code, documentation, ideas, or problem statements to this project.
-
-### Defining the problem
-
-If you have an idea for a new feature or if you've discovered a bug in `dbt-core`, the first step is to open an issue. Please check the list of [open issues](https://github.com/dbt-labs/dbt-core/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-core` 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-core` 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-core` 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.
-
-### Submitting a change
-
-If an issue is appropriately well scoped and describes a beneficial change to the `dbt-core` codebase, then anyone may submit a Pull Request to implement the functionality described in the issue. See the sections below on how to do this.
-
-The `dbt-core` 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. You can see the list of currently open issues on the [Contribute](https://github.com/dbt-labs/dbt-core/contribute) page.
-
-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-core` 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-core`'s [unit](test/unit) and [integration](test/integration) tests is the tests themselves. One of the maintainers can help by pointing out relevant examples.
-- Check your formatting and linting with [Flake8](https://flake8.pycqa.org/en/latest/#), [Black](https://github.com/psf/black), and the rest of the hooks we have in our [pre-commit](https://pre-commit.com/) [config](https://github.com/dbt-labs/dbt-core/blob/75201be9db1cb2c6c01fa7e71a314f5e5beb060a/.pre-commit-config.yaml).
-
-In some cases, the right resolution to an open issue might be tangential to the `dbt-core` codebase. The right path forward might be a documentation update or a change that can be made in user-space. In other cases, the issue might describe functionality that the `dbt-core` maintainers are unwilling or unable to incorporate into the `dbt-core` codebase. When it is determined that an open issue describes functionality that will not translate to a code change in the `dbt-core` repository, the issue will be tagged with the `wontfix` label (see below) and closed.
-
-### Using issue labels
-
-The `dbt-core` maintainers use labels to categorize open issues. Most labels describe the domain in the `dbt-core` codebase germane to the discussion.
-
-| tag | description |
-| --- | ----------- |
-| [triage](https://github.com/dbt-labs/dbt-core/labels/triage) | This is a new issue which has not yet been reviewed by a `dbt-core` maintainer. This label is removed when a maintainer reviews and responds to the issue. |
-| [bug](https://github.com/dbt-labs/dbt-core/labels/bug) | This issue represents a defect or regression in `dbt-core` |
-| [enhancement](https://github.com/dbt-labs/dbt-core/labels/enhancement) | This issue represents net-new functionality in `dbt-core` |
-| [good first issue](https://github.com/dbt-labs/dbt-core/labels/good%20first%20issue) | This issue does not require deep knowledge of the `dbt-core` codebase to implement. This issue is appropriate for a first-time contributor. |
-| [help wanted](https://github.com/dbt-labs/dbt-core/labels/help%20wanted) / [discussion](https://github.com/dbt-labs/dbt-core/labels/discussion) | Conversation around this issue in ongoing, and there isn't yet a clear path forward. Input from community members is most welcome. |
-| [duplicate](https://github.com/dbt-labs/dbt-core/issues/duplicate) | This issue is functionally identical to another open issue. The `dbt-core` maintainers will close this issue and encourage community members to focus conversation on the other one. |
-| [snoozed](https://github.com/dbt-labs/dbt-core/labels/snoozed) | This issue describes a good idea, but one which will probably not be addressed in a six-month time horizon. The `dbt-core` maintainers will revist these issues periodically and re-prioritize them accordingly. |
-| [stale](https://github.com/dbt-labs/dbt-core/labels/stale) | This is an old issue which has not recently been updated. Stale issues will periodically be closed by `dbt-core` maintainers, but they can be re-opened if the discussion is restarted. |
-| [wontfix](https://github.com/dbt-labs/dbt-core/labels/wontfix) | This issue does not require a code change in the `dbt-core` repository, or the maintainers are unwilling/unable to merge a Pull Request which implements the behavior described in the issue. |
-
-#### Branching Strategy
-
-`dbt-core` has three types of branches:
-
-- **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.
-- **Release Branches** track a specific, not yet complete release of `dbt-core`. 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-core`.
-- **Feature Branches** track individual features and fixes. On completion they should be merged into the trunk branch or a specific release branch.
+- **Adapters:** Is your issue or proposed code change related to a specific [database adapter](https://docs.getdbt.com/docs/available-adapters)? If so, please open issues, PRs, and discussions in that adapter's repository instead. The sole exception is Postgres; the `dbt-postgres` plugin lives in this repository (`dbt-core`).
+- **CLA:** Please note that anyone contributing code to `dbt-core` must sign the [Contributor License Agreement](https://docs.getdbt.com/docs/contributor-license-agreements). If you are unable to sign the CLA, the `dbt-core` maintainers will unfortunately be unable to merge any of your Pull Requests. We welcome you to participate in discussions, open issues, and comment on existing ones.
+- **Branches:** All pull requests from community contributors should target the `main` branch (default). If the change is needed as a patch for a minor version of dbt that has already been released (or is already a release candidate), a maintainer will backport the changes in your PR to the relevant "latest" release branch (`1.0.latest`, `1.1.latest`, ...)

 ## Testing
 
-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.
+Once you're able to manually test that your code change is working as expected, it's important to run existing automated tests, as well as adding some new ones. These tests will ensure that:
+- Your code changes do not unexpectedly break other established functionality
+- Your code changes can handle all known edge cases
+- The functionality you're adding will _keep_ working in the future
 
-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.

 ## Submitting a Pull Request
 
-dbt Labs provides a CI environment to test changes to specific adapters, and periodic maintenance checks of `dbt-core` through Github Actions. For example, if you submit a pull request to the `dbt-redshift` repo, GitHub will trigger automated code checks and tests against Redshift.
-
 A `dbt-core` maintainer will review your PR. They may suggest code revision for style or clarity, or request that you add unit or integration test(s). These are good things! We believe that, with a little bit of help, anyone can contribute high-quality code.
-- First time contributors should note code checks + unit tests require a maintainer to approve.
 
+Automated tests run via GitHub Actions. If you're a first-time contributor, all tests (including code checks and unit tests) will require a maintainer to approve. Changes in the `dbt-core` repository trigger integration tests against Postgres. dbt Labs also provides CI environments in which to test changes to other adapters, triggered by PRs in those adapters' repositories, as well as periodic maintenance checks of each adapter in concert with the latest `dbt-core` code changes.
 
 Once all tests are passing and your PR has been approved, a `dbt-core` maintainer will merge your changes into the active development branch. And that's it! Happy developing :tada:

 # 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.
