+Add a new `push-git-tags` option that complements `create-github-releases` to control specifically if git tags should be created but not GitHub releases.

 # @changesets/action
 
+## 2.0.0-next.3
+
+### Major Changes
+
+- [#680](https://github.com/changesets/action/pull/680) [`ca57073`](https://github.com/changesets/action/commit/ca57073900dc678254406a052a03c0c8824e319d) Thanks [@bluwy](https://github.com/bluwy)! - Add a new `push-git-tags` option that complements `create-github-releases` to control specifically if git tags should be created but not GitHub releases.
+
+  If `create-github-releases` was previously set to `false`, which also indirectly disabled git tag creation, git tags will now be created instead by default. If this is not desired, set `push-git-tags` to `false` explicitly.
+
+- [#681](https://github.com/changesets/action/pull/681) [`7359107`](https://github.com/changesets/action/commit/73591071e61c7f61cf322dd7a6341dc29a8e1d4e) Thanks [@bluwy](https://github.com/bluwy)! - Rename the root action inputs and outputs to better match the sub-actions' conventions.
+
+  Inputs:
+  - `version` -> `version-script`
+  - `publish` -> `publish-script`
+  - `commit` -> `commit-message`
+  - `title` -> `pr-title`
+  - `branch` -> `pr-base-branch`
+
+  Outputs:
+  - `pull-request-number` -> `pr-number`
+
+- [#674](https://github.com/changesets/action/pull/674) [`164652b`](https://github.com/changesets/action/commit/164652bdd60525670d95291addb8c6f92833ac60) Thanks [@bluwy](https://github.com/bluwy)! - Remove support for passing custom GitHub token through the GITHUB_TOKEN environment variable. It should be passed to the `github-token` input instead.
+
+- [#673](https://github.com/changesets/action/pull/673) [`823cf74`](https://github.com/changesets/action/commit/823cf741ca57c5e22652123d3a847dfafcd77ca0) Thanks [@bluwy](https://github.com/bluwy)! - Update to Changesets v3 packages
+
+- [#668](https://github.com/changesets/action/pull/668) [`0eae789`](https://github.com/changesets/action/commit/0eae789230defbc4ad287e9b476aba7e842e34e0) Thanks [@bluwy](https://github.com/bluwy)! - Rename the input and output names to kebab-case instead of camelCase to match the official GitHub actions pattern
+
+### Minor Changes

+- [#678](https://github.com/changesets/action/pull/678) [`f71ae04`](https://github.com/changesets/action/commit/f71ae043ed5deb17952900091e009a60edef9507) Thanks [@Andarist](https://github.com/Andarist)! - Published packages detection done through stdout parsing was replaced with one based on the shared output file using `CHANGESETS_OUTPUT` environment variable. When using custom scripts this environment variable should always be passed down to the Changesets CLI invocations.

+
+- [#535](https://github.com/changesets/action/pull/535) [`34f64f6`](https://github.com/changesets/action/commit/34f64f6e2e1e47ddc183f174aa27c197aa47f520) Thanks [@Andarist](https://github.com/Andarist)! - Fixed an issue with GitHub releases not being created for successfully published packages when _some_ packages failed to be published to the registry.
+

This should remove a possibility of a GitHub state race that caused the force-pushed PRs not being reopened.

Use `create` to create new version PRs as drafts, or `always` to also convert existing version PRs back to draft when updating them.
+
+### Patch Changes

 This action for [Changesets](https://github.com/changesets/changesets) creates a pull request with all of the package versions updated and changelogs updated and when there are new changesets on [your configured `baseBranch`](https://github.com/changesets/changesets/blob/main/docs/config-file-options.md#basebranch-git-branch-name), the PR will be updated. When you're ready, you can merge the pull request and you can either publish the packages to npm manually or setup the action to do it for you.
 
+There are also sub-actions hosted in this repository. Check out their respective READMEs for more details:
+
+- [pr-status](./pr-status/README.md): Generate changeset status in PRs.
+- [pr-comment](./pr-comment/README.md): Comment on PRs.

 ## Usage
 
 ### Inputs
@@ -14,13 +22,14 @@ This action for [Changesets](https://github.com/changesets/changesets) creates a
 - createGithubReleases - A boolean value to indicate whether to create Github releases after `publish` or not. Default to `true`
 - commitMode - Specifies the commit mode. Use `"git-cli"` to push changes using the Git CLI, or `"github-api"` to push changes via the GitHub API. When using `"github-api"`, all commits and tags are GPG-signed and attributed to the user or app who owns the `GITHUB_TOKEN`. Default to `git-cli`.
 - cwd - Changes node's `process.cwd()` if the project is not located on the root. Default to `process.cwd()`
+- prDraft - Controls draft PR behavior. Use `create` to create new version PRs as draft, or `always` to also convert existing version PRs back to draft when updating them. By default, version PRs are not forced into draft mode.
 
 ### Outputs
 
 - published - A boolean value to indicate whether a publishing has happened or not
 - publishedPackages - A JSON array to present the published packages. The format is `[{"name": "@xx/xx", "version": "1.2.0"}, {"name": "@xx/xy", "version": "0.8.9"}]`

+# @changesets/action/pr-comment
+
+A simple GitHub Action to comment on PRs aimed to complement [`@changesets/action/pr-status`](../pr-status/README.md).
+
+This action is intentionally simple without advanced features. Check out other actions if so, such as [mshick/add-pr-comment](https://github.com/marketplace/actions/add-pr-comment) and [peter-evans/create-or-update-comment](https://github.com/marketplace/actions/create-or-update-comment).
+
+See the [action metadata](action.yml) for details on the inputs and outputs.
+
+## Example setup
+
+```yaml
+name: PR Comment
+
+on:
+  pull_request:
+
+jobs:
+  pr-comment:
+    runs-on: ubuntu-slim
+    permissions:
+      pull-requests: write # to create and update comments on PRs
+    steps:
+      - uses: changesets/action/pr-comment@v1
+        with:
+          body: Hello world!
+```
+
+When called repeatedly, the action will update the comment it created by default. If you use this action to create different types of comments, pass an `update-id` value to differentiate them.
+
+```yaml
+jobs:
+  pr-comment:
+    # ...
+    steps:
+      - uses: changesets/action/pr-comment@v1
+        with:
+          body: Hello world!
+          update-id: my-tag
+```
+
+If you want to always create new comments, pass an empty value to `update-id`.
+
+```yaml
+jobs:
+  pr-comment:
+    # ...
+    steps:
+      - uses: changesets/action/pr-comment@v1
+        with:
+          body: Hello world!

+# changesets/action/pr-status
+
+This action generates the changesets status in PRs, e.g. whether it has changeset files and which packages will be released if the PR is merged.
+
+It requires the repo to be checked out, and automatically fetches the PR head ref into a temporary detached worktree in order to infer the changed files and packages.
+
+See the [action metadata](action.yml) for details on the inputs and outputs.
+
+> [!CAUTION]
+> **This action uses `pull_request_target` by default to support PRs from forks.**
+>
+> **Do not run untrusted code** when using the `pull_request_target` event.
+>
+> The example below only **_checks out_** and **_reads_** code, and does not **_execute_** any code from the fork.
+>
+> Read more about the `pull_request_target` event in the [GitHub documentation](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows#pull_request_target).
+
+You can also use the [`pull_request`](https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows#pull_request) event if you prefer to lock permissions down and not run for PRs from forks. Make sure to add an if check to prevent the action from failing in fork PRs:
+
+```yaml
+jobs:
+  pr-status:
+    if: github.event.pull_request.head.repo.full_name == github.repository
+    # ...
+```
+
+You can also use the [Changesets Bot](https://github.com/apps/changeset-bot) if you don't want an extra action in your repo, or are worried about the `pull_request_target` event.
+
+## Example setup
+
+```yaml
+# .github/workflows/comment-changesets-pr-status.yml
+name: Comment Changesets status in PRs
+
+on:
+  pull_request_target:
+
+permissions: {} # require explicitly stating all permissions in each job

+    steps:

+        with:
+          body: ${{ needs.pr-status.outputs.comment-body }}
+```
+
+The workflow uses [`@changesets/action/pr-comment`](../pr-comment/README.md), which is a simple GitHub Action to comment on PRs.
