+
+## 1.5.3
+
+### Patch Changes

+
+- [#479](https://github.com/changesets/action/pull/479) [`cf373e4`](https://github.com/changesets/action/commit/cf373e45c90a0cc564cd2770de3e9a3a4cdd4603) Thanks [@Andarist](https://github.com/Andarist)! - Switched to `esbuild` for bundling the dist file. This led to 45% file size reduction.
+
+- [#488](https://github.com/changesets/action/pull/488) [`022692b`](https://github.com/changesets/action/commit/022692ba027b33bf46d4d41907a317fbf04461a7) Thanks [@s0](https://github.com/s0)! - Fix PRs sometimes not getting reopened with `commitMode: github-api`
+
+  There was a race-condition that means sometimes existing PRs would not be found,
+  and new PRs would be opened. This has now been fixed by fetching existing PRs
+  before making any changes.
+
+- [#486](https://github.com/changesets/action/pull/486) [`7ed1955`](https://github.com/changesets/action/commit/7ed195554624ebd75c08aa477b53110f61cc78f7) Thanks [@s0](https://github.com/s0)! - Fixed situations in which `cwd` was specified as a relative path and used with (default) `commitMode: git-cli`
+
+- [#461](https://github.com/changesets/action/pull/461) [`e9c36b6`](https://github.com/changesets/action/commit/e9c36b696406360bf04204ad32e3dcf3ad752b77) Thanks [@nayounsang](https://github.com/nayounsang)! - Avoid hitting a deprecation warning when encountering errors from `@octokit/request-error`

+
+  Ensure that when running the action from a subdirectory of a repository,
+  only the files from that directory are added, regardless of `commitMode`.
+
+## 1.5.1
+
+### Patch Changes
+
+- [#471](https://github.com/changesets/action/pull/471) [`15ab130`](https://github.com/changesets/action/commit/15ab1306067a396fa9ba7ad363e8a041d457782a) Thanks [@h3rmanj](https://github.com/h3rmanj)! - Bump `@changesets/ghcommit` to v1.4.0, which fixes an issue running this action in monorepos with `commitMode: github-api`
+

+
+  When used with `"github-api"` value all tags and commits will be attributed to the user whose GITHUB_TOKEN is used, and also signed using GitHub's internal GPG key.

+
+## 1.4.3
+

+
+- [#289](https://github.com/changesets/action/pull/289) [`8b28186`](https://github.com/changesets/action/commit/8b2818674de86a7fc69aebb9ed6b486ee32eb96e) Thanks [@varl](https://github.com/varl)! - Use logging provided by `@actions/core`
+
+## 1.4.2
+
+### Patch Changes
+
+- [#286](https://github.com/changesets/action/pull/286) [`225a1e8`](https://github.com/changesets/action/commit/225a1e8cbcabb7b585174ba0ad806549db40d4cd) Thanks [@varl](https://github.com/varl)! - This patch implements the [`@octokit/plugin-throttling`](https://github.com/octokit/plugin-throttling.js) plugin and [wires
+  it up with the internal GitHub Octokit instance](https://github.com/actions/toolkit/tree/457303960f03375db6f033e214b9f90d79c3fe5c/packages/github#extending-the-octokit-instance).
+
+  This plugin is recommended by [the Octokit docs](://octokit.github.io/rest.js/v19#throttling) as it implements all the GitHub [best practices for integrators](https://docs.github.com/en/rest/guides/best-practices-for-integrators?apiVersion=2022-11-28).
+
+  This should help with `changesets/action` gitting spurious secondary rate limits and failing CI jobs, for which the only known workaround is to simply re-run the job.

This fixes an issue with user-owned PATs.
+
+* [#206](https://github.com/changesets/action/pull/206) [`8c3f5f5`](https://github.com/changesets/action/commit/8c3f5f5637a95a2327e78d5dabcf357978aedcbb) Thanks [@glasser](https://github.com/glasser)! - Skip creating a PR when all existing changesets are empty.

 # Changesets Release Action
 
-This action for [Changesets](https://github.com/atlassian/changesets) creates a pull request with all of the package versions updated and changelogs updated and when there are new changesets on master, 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.

 - 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`

+#### 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.
