+# CHANGELOG
+
+This is a manually generated log to track changes to the repository for each release. 
+Each section should include general headers such as **Implemented enhancements** 
+and **Merged pull requests**. All closed issued and bug fixes should be 
+represented by the pull requests that fixed them. Critical items to know are:
+
+ - renamed commands
+ - deprecated / removed commands
+ - changed defaults
+ - backward incompatible changes
+
+
+Versions correspond with GitHub releases that can be referenced with @ using actions.
+
+## [master](https://github.com/vsoch/pull-request-action/tree/master) (master)
+  - output and environment variables for PR number and return codes (1.0.5)
+  - added support for reviewer (individual and team) assignments (1.0.4)
+  - added support for maintainer can modify and assignees (1.0.3)

-All booleans should be lowercase.
+For `PULL_REQUEST_DRAFT`, `PASS_ON_ERROR`, and `MAINTAINER_CANT_MODIFY`, these are
+treated as environment booleans. If they are defined in the environment, they trigger the
+"true" condition. E.g.,:
+
+ - Define `MAINTAINER_CANT_MODIFY` if you don't want the maintainer to be able to modify the pull request.
+ - Define `PULL_REQUEST_DRAFT` if you want the PR to be a draft.
+ - Define `PASS_ON_ERROR` if you want the PR to not exit given any non 200/201 response.
+
+For `PULL_REQUEST_ASSIGNEES`, `PULL_REQUEST_REVIEWERS`, and `PULL_REQUEST_TEAM_REVIEWERS` 
+you can provide a string of one or more GitHub usernames (or team names) to
+assign to the issue. Note that only users with push access can add assigness to 
+an issue or PR, they are ignored otherwise.
 
 The `GITHUB_TOKEN` secret is required to interact and authenticate with the GitHub API to open
 the pull request. The example is [deployed here](https://github.com/vsoch/pull-request-action-example) with an example opened (and merged) [pull request here](https://github.com/vsoch/pull-request-action-example/pull/1) if needed.
 
+## Outputs
+
+The action sets a few useful output and environment variables. An output can
+be referenced later as `${{ steps.<stepname>.outputs.<output-name> }}`.
+An environment variable of course can be referenced as you usually would.
+
+| Name | Description | Environment | 
+|------|-------------|-------------|
+| pull_request_number |If the pull request is opened, this is the number for it. | PULL_REQUEST_NUMBER |
+| pull_request_url |If the pull request is opened, the html url for it. | PULL_REQUEST_URL |
+| pull_request_return_code | Return code for the pull request | PULL_REQUEST_RETURN_CODE |
+| assignees_return_code | Return code for the assignees request | ASSIGNEES_RETURN_CODE |
+| reviewers_return_code | Return code for the reviewers request | REVIEWERS_RETURN_CODE |
+
+See the [examples/outputs-example.yml](examples/outputs-example.yml) for how this works. 
+In this example, we can reference `${{ steps.pull_request.outputs.pull_request_url }}`
+in either another environment variable declaration, or within a run statement to access
+our variable `pull_request_url` that was generated in a step with id `pull_request`.
+The screenshot below shows the example in action to interact with outputs in several ways.
