+
+- [#724](https://github.com/changesets/action/pull/724) [`36f529f`](https://github.com/changesets/action/commit/36f529f13ab58bbcf6331035cb950385586e8a89) Thanks [@bluwy](https://github.com/bluwy)! - Improve log messages
+
+- [#724](https://github.com/changesets/action/pull/724) [`36f529f`](https://github.com/changesets/action/commit/36f529f13ab58bbcf6331035cb950385586e8a89) Thanks [@bluwy](https://github.com/bluwy)! - Fix root action double error logs
+
+- [#729](https://github.com/changesets/action/pull/729) [`ca85897`](https://github.com/changesets/action/commit/ca8589735af2ff6977a0f6474537d550040530d8) Thanks [@bluwy](https://github.com/bluwy)! - Always switch and reset branch when generating version commits, similar to if `push-with-git-cli` is enabled
+
+## 2.1.1
+
+### Patch Changes
+
+- [#721](https://github.com/changesets/action/pull/721) [`da1ea29`](https://github.com/changesets/action/commit/da1ea291ef93203a08fad360eac36f4858dd0514) Thanks [@KEBABSELLER6](https://github.com/KEBABSELLER6)! - Fixed typo in renamed inputs from v1 to v2
+
+## 2.1.0
+
+### Minor Changes
+
+- [#718](https://github.com/changesets/action/pull/718) [`3b7c71c`](https://github.com/changesets/action/commit/3b7c71c440e75fca5d335f779290425fc1117fe8) Thanks [@bluwy](https://github.com/bluwy)! - Add a `cwd` input to the root action, `/select-mode`, `/version`, `/pack`, and `/publish` sub-actions to set the current working directory to execute Changesets in. This input existed in v1 but was incorrectly removed.
+
+### Patch Changes
+
+- [#716](https://github.com/changesets/action/pull/716) [`6f58ba3`](https://github.com/changesets/action/commit/6f58ba35801ec075a1c87569277591f8ef1a3029) Thanks [@bluwy](https://github.com/bluwy)! - Update `pr-status` message to link to the new faq page
+
+## 2.0.0
+
+### Major Changes
+
+- [#692](https://github.com/changesets/action/pull/692) [`cb3f011`](https://github.com/changesets/action/commit/cb3f0110d7423cd340b1c5d63584c0ea6ee63959) Thanks [@Andarist](https://github.com/Andarist)! - Release commits and tags are now pushed using the GitHub API by default.
+
+  Replace the `commit-mode` input with the boolean `push-with-git-cli` input. Set `push-with-git-cli: true` to continue using the Git CLI.
+
+  Regardless of the push mode, custom GitHub tokens must be passed explicitly through the `github-token` input. The `GITHUB_TOKEN` environment variable and credentials configured by `actions/checkout` or embedded in remote URLs are not substitutes for this input. When the Git CLI is enabled, `github-token` takes precedence over those repository credentials.
+
+- [#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.
+
+- [#657](https://github.com/changesets/action/pull/657) [`4f718b5`](https://github.com/changesets/action/commit/4f718b5921490b1efeb015a81abb6a4633892851) Thanks [@Andarist](https://github.com/Andarist)! - Removed compatibility support for old Changesets v1.
+
+- [#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`

+
+- [#659](https://github.com/changesets/action/pull/659) [`5649ff4`](https://github.com/changesets/action/commit/5649ff41b8eb1b7a281011e45df781c6d4628fd0) Thanks [@bluwy](https://github.com/bluwy)! - Remove `cwd` option for `changesets/action`. Use the step `working-directory` option instead to change the directory.
+

+
+- [#695](https://github.com/changesets/action/pull/695) [`469993c`](https://github.com/changesets/action/commit/469993ce5783c6a38e72541d4ba0d25588702b9a) Thanks [@bluwy](https://github.com/bluwy)! - Removed `.npmrc` handling when the `NPM_TOKEN` environment variable is set.
+
+  Authentication should be handled via Trusted Publishing instead. If a token is still needed, use `actions/setup-node` to set it up instead via the `registry-url` option. Check out the updated action README for more information of setting up npm authentication in GitHub Actions.
+
+- [#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
+
+- [#656](https://github.com/changesets/action/pull/656) [`a12d90d`](https://github.com/changesets/action/commit/a12d90de8394e63c952622b2fd3f98c8729c48b0) Thanks [@bluwy](https://github.com/bluwy)! - Add new `/select-mode`, `/version`, and `/publish` sub-actions to better control version and publish steps
+
+- [#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.
+
+### Patch Changes
+
+- [#699](https://github.com/changesets/action/pull/699) [`5b307d3`](https://github.com/changesets/action/commit/5b307d3df25daf51c41dff70d2f66df1579ae9fa) Thanks [@Andarist](https://github.com/Andarist)! - Validate that projects use Changesets CLI v3 and direct Changesets CLI v2 users to `changesets/action@v1`.
+
+- [#697](https://github.com/changesets/action/pull/697) [`84d78c6`](https://github.com/changesets/action/commit/84d78c68f98f20e24dfff22b22193e7b4f326ad9) Thanks [@Andarist](https://github.com/Andarist)! - Allow custom publish scripts to complete without a Changesets output file, warning that GitHub releases and git tags cannot be created when that file is missing.
+
+- [#670](https://github.com/changesets/action/pull/670) [`5a8b9b7`](https://github.com/changesets/action/commit/5a8b9b721bf683e3bf9bd72ea92a685dc024147b) Thanks [@Andarist](https://github.com/Andarist)! - Authenticate git CLI pushes with the configured GitHub token using Git extra headers instead of writing to a global `.netrc` file.
+
+- [#670](https://github.com/changesets/action/pull/670) [`5a8b9b7`](https://github.com/changesets/action/commit/5a8b9b721bf683e3bf9bd72ea92a685dc024147b) Thanks [@Andarist](https://github.com/Andarist)! - Derive the Git server URL from the GitHub Actions context when configuring git CLI authentication to support GitHub Enterprise Server setups.
+
+- [#688](https://github.com/changesets/action/pull/688) [`219ea82`](https://github.com/changesets/action/commit/219ea82e52caaff2a10a5e34d3455093cf958238) Thanks [@Andarist](https://github.com/Andarist)! - Remove the `setup-git-user` input. Complete custom Git identities are now preserved automatically, while `github-actions[bot]` is configured as a fallback before creating local release commits or tags.
+

-# Changesets Release Action
+# Changesets GitHub Action
 
-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.
+> [!IMPORTANT]
+> This is the development branch for `changesets/action` v2 compatible with Changesets v3. For the v1 code compatible with Changesets v2, check out the [`maintenance/v1`](https://github.com/changesets/action/tree/maintenance/v1) branch.
 
-## Usage
+This repo contains a collection of GitHub Actions for [Changesets](https://changesets.dev). Check out the [Automating Changesets](https://changesets.dev/guide/automating) guide to learn how to use these actions to automate your workflow.
 
-### Inputs
+- [changesets/action](./README.md): (This README. See below for details.)
+- [changesets/action/select-mode](./select-mode/README.md): Select the mode to run a Changesets workflow.
+- [changesets/action/version](./version/README.md): Version packages and create or update a pull request with the changes.
+- [changesets/action/pack](./pack/README.md): Pack publishable packages into tarballs.
+- [changesets/action/publish](./publish/README.md): Publish packages to npm.
+- [changesets/action/pr-status](./pr-status/README.md): Generate changeset status in PRs.
+- [changesets/action/pr-comment](./pr-comment/README.md): Create or update comments on PRs.
 
-- publish - The command to use to build and publish packages
+## changesets/action
-- version - The command to update version, edit CHANGELOG, read and delete changesets. Default to `changeset version` if not provided
-- commit - The commit message to use. Default to `Version Packages`
-- title - The pull request title. Default to `Version Packages`
-- setupGitUser - Sets up the git user for commits as `"github-actions[bot]"`. Default to `true`
-- 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()`
 
-### Outputs
+This action handles versioning and publishing of packages. It's the equivalent of setting up the `changesets/action/select-mode`, `changesets/action/version`, and `changesets/action/publish` actions in a workflow, but with the required permissions combined.
 
-- published - A boolean value to indicate whether a publishing has happened or not
+If using [trusted publishing](https://docs.npmjs.com/trusted-publishers), it's recommended to set up the individual sub-actions instead to tighten publish permissions.
-- 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"}]`
 
-### Example workflow:
+### Requirements
 
-#### Without Publishing
+- Needs repo checked out and `@changesets/cli` installed
+- [Job permissions][job-permissions]:
+  - `contents: write`: to commit version changes
+  - `pull-requests: write`: to create pull request
+  - `id-token: write`: if using [trusted publishing](https://docs.npmjs.com/trusted-publishers)
+- [Workflow triggers][workflow-triggers]: _any_
 
-Create a file at `.github/workflows/release.yml` with the following content.
+> [!NOTE]
+> In your repository settings, in `Actions > General`, also ensure the `Allow GitHub Actions to create and approve pull requests` option is enabled
 
-```yml

+> [!TIP]
-  push:
+> Check out [the docs](https://changesets.dev/guide/automating#how-do-i-run-the-version-and-publish-commands) to learn how to set up the version and publish workflow.
-    branches:
-      - main
 
-concurrency: ${{ github.workflow }}-${{ github.ref }}
+> [!IMPORTANT]
+> To use a custom GitHub token, pass it explicitly through the `github-token` input:
+>
+> ```yaml
+> with:
+>   github-token: ${{ secrets.CUSTOM_GITHUB_TOKEN }}
+> ```
+>
+> Setting the `GITHUB_TOKEN` environment variable does not configure the action. This applies whether release changes are pushed using the GitHub API or the Git CLI.

-#### With Publishing
+<!-- api-end -->
 
-Before you can setup this action with publishing, you'll need to have an [npm token](https://docs.npmjs.com/creating-and-viewing-authentication-tokens) that can publish the packages in the repo you're setting up the action for and doesn't have 2FA on publish enabled ([2FA on auth can be enabled](https://docs.npmjs.com/about-two-factor-authentication)). You'll also need to [add it as a secret on your GitHub repo](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables) with the name `NPM_TOKEN`. Once you've done that, you can create a file at `.github/workflows/release.yml` with the following content.

-        run: my-slack-bot send-notification --message "A new version of ${GITHUB_REPOSITORY} was published!"
-```
-
-By default the GitHub Action creates a `.npmrc` file with the following content:
-
-```
-//registry.npmjs.org/:_authToken=${process.env.NPM_TOKEN}
-```
-
-However, if a `.npmrc` file is found, the GitHub Action does not recreate the file. This is useful if you need to configure the `.npmrc` file on your own.
-For example, you can add a step before running the Changesets GitHub Action:
-
-```yml
-- name: Creating .npmrc
-  run: |
-    cat << EOF > "$HOME/.npmrc"
-      //registry.npmjs.org/:_authToken=$NPM_TOKEN
-    EOF
-  env:
-    NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
-```
-
-#### Custom Publishing
-
-If you want to hook into when publishing should occur but have your own publishing functionality, you can utilize the `hasChangesets` output.
-
-Note that you might need to account for things already being published in your script because a commit without any new changesets can always land on your base branch after a successful publish. In such a case you need to figure out on your own how to skip over the actual publishing logic or handle errors gracefully as most package registries won't allow you to publish over already published version.
-
-```yml
-name: Release
-
-on:
-  push:
-    branches:
-      - main
-
-jobs:
-  release:
-    name: Release
-    runs-on: ubuntu-latest
-    steps:
-      - name: Checkout Repo
-        uses: actions/checkout@v3
-
-      - name: Setup Node.js 20.x
-        uses: actions/setup-node@v3
-        with:
-          node-version: 20.x
-
-      - name: Install Dependencies
-        run: yarn
-
-      - name: Create Release Pull Request or Publish to npm
-        id: changesets
-        uses: changesets/action@v1
-        env:
-          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-
-      - name: Publish
-        if: steps.changesets.outputs.hasChangesets == 'false'
-        # You can do something when a publish should happen.
-        run: yarn publish
-```
-
-#### With version script
-
-If you need to add additional logic to the version command, you can do so by using a version script.
-
-If the version script is present, this action will run that script instead of `changeset version`, so please make sure that your script calls `changeset version` at some point. All the changes made by the script will be included in the PR.
-
-```yml
-name: Release
-
-on:
-  push:
-    branches:
-      - main
-
-concurrency: ${{ github.workflow }}-${{ github.ref }}
-
-jobs:
-  release:
-    name: Release
-    runs-on: ubuntu-latest
-    steps:
-      - name: Checkout Repo
-        uses: actions/checkout@v3
-
-      - name: Setup Node.js 20.x
-        uses: actions/setup-node@v3
-        with:
-          node-version: 20.x

-
-      - name: Create Release Pull Request
-        uses: changesets/action@v1
-        with:
-          # this expects you to have a npm script called version that runs some logic and then calls `changeset version`.
-          version: yarn version
-        env:
-          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-```
-
-#### With Yarn 2 / Plug'n'Play
-
-If you are using [Yarn Plug'n'Play](https://yarnpkg.com/features/pnp), you should use a custom `version` command so that the action can resolve the `changeset` CLI:
-
-```yaml
-- uses: changesets/action@v1
-  with:
-    version: yarn changeset version
-    ...
-```

+# changesets/action/pr-comment
+
+This action creates or updates comments on PRs, aimed to complement [changesets/action/pr-status](../pr-status/README.md).
+
+Its features are kept intentionally simple. For advanced usecases, check out other actions 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).
+
+## Requirements
+
+- [Job permissions][job-permissions]:
+  - `pull-requests: write`: to create and update comments on PRs
+- [Workflow triggers][workflow-triggers]:
+  - [`pull_request`][trigger-pull-request]
+  - [`pull_request_target`][trigger-pull-request-target]
+
+> [!CAUTION]
+> **Do not run untrusted code** when using the `pull_request_target` event.
+>
+> `pull_request_target` can be useful to support PRs from forks, however it enables write permissions by default which can be a security risk if untrusted code is executed and the permissions aren't scoped down.
+
+## Usage
+
+> [!TIP]
+> Check out [the docs](https://changesets.dev/guide/automating#non-blocking) to learn how to set up commenting changesets status on PRs.
+
+```yaml
+on:
+  pull_request:
+
+jobs:
+  pr-comment:
+    runs-on: ubuntu-slim
+    permissions:
+      pull-requests: write # to create and update comments on PRs (changesets/action/pr-comment)
+    steps:
+      - name: Comment on PR
+        uses: changesets/action/pr-comment@v2
+        with:
+          body: Hello world!
+```
+
+If the action is called again for the same PR, for example, if called in another workflow run, it will update the comment it created by default.
+
+If you use the action to create different types of comments, pass an `update-id` value to differentiate them.
+
+```yaml
+jobs:
+  pr-comment:
+    # ...
+    steps:
+      - name: Comment on PR
+        uses: changesets/action/pr-comment@v2
+        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@v2
+        with:
+          body: Hello world!
+          update-id: ""

+# changesets/action/pr-status
+
+This action generates the changesets status in PRs, for example, 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 will automatically fetch the PR head ref into a temporary detached worktree in order to infer the changed files and packages.
+
+## Requirements
+
+- Needs repo checked out
+- [Job permissions][job-permissions]: _none_
+- [Workflow triggers][workflow-triggers]:
+  - [`pull_request`][trigger-pull-request]
+  - [`pull_request_target`][trigger-pull-request-target]
+
+> [!CAUTION]
+> **Do not run untrusted code** when using the `pull_request_target` event.
+>
+> `pull_request_target` can be useful to support PRs from forks, however it enables write permissions by default which can be a security risk if untrusted code is executed and the permissions aren't scoped down.

+# changesets/action/version
+
+This action versions packages and creates or updates a pull request with the changes.
+
+## Requirements
+
+- Needs repo checked out and `@changesets/cli` installed
+- [Job permissions][job-permissions]:
+  - `contents: write`: to commit version changes
+  - `pull-requests: write`: to create pull request
+- [Workflow triggers][workflow-triggers]: _any_
+
+> [!NOTE]
+> In your repository settings, in `Actions > General`, also ensure the `Allow GitHub Actions to create and approve pull requests` option is enabled
+
+## Usage
+
+> [!TIP]
+> Check out [the docs](https://changesets.dev/guide/automating#how-do-i-run-the-version-and-publish-commands) to learn how to set up the version and publish workflow.
