# [Release Please](https://github.com/googleapis/release-please)



[![npm version](https://img.shields.io/npm/v/release-please.svg)](https://www.npmjs.org/package/release-please)

[![codecov](https://img.shields.io/codecov/c/github/googleapis/release-please/main.svg?style=flat)](https://codecov.io/gh/googleapis/release-please)



Release Please automates CHANGELOG generation, the creation of GitHub releases,

and version bumps for your projects.



It does so by parsing your

git history, looking for [Conventional Commit messages](https://www.conventionalcommits.org/),

and creating release PRs.



It does not handle publication to package managers or handle complex branch

management.



## What's a Release PR?



Rather than continuously releasing what's landed to your default branch,

release-please maintains Release PRs:






These Release PRs are kept up-to-date as additional work is merged. When you're

ready to tag a release, simply merge the release PR. Both squash-merge and

merge commits work with Release PRs.



When the Release PR is merged, release-please takes the following steps:



1. Updates your changelog file (for example `CHANGELOG.md`), along with other language specific files (for example `package.json`).

2. Tags the commit with the version number

3. Creates a GitHub Release based on the tag



You can tell where the Release PR is in its lifecycle by the status label on the

PR itself:



- `autorelease: pending` is the initial state of the Release PR before it is merged

- `autorelease: tagged` means that the Release PR has been merged and the release has been tagged in GitHub

- `autorelease: snapshot` is a special state for snapshot version bumps

- `autorelease: published` means that a GitHub release has been published based on the Release PR (_release-please does not automatically add this tag, but we recommend it as a convention for publication tooling_).



## How should I write my commits?



Release Please assumes you are using [Conventional Commit messages](https://www.conventionalcommits.org/).



The most important prefixes you should have in mind are:



* `fix:` which represents bug fixes, and correlates to a [SemVer](https://semver.org/)

  patch.

* `feat:` which represents a new feature, and correlates to a SemVer minor.

* `feat!:`,  or `fix!:`, `refactor!:`, etc., which represent a breaking change

  (indicated by the `!`) and will result in a SemVer major.



### Linear git commit history (use squash-merge)



We **highly** recommend that you use squash-merges when merging pull requests.

A linear git history makes it much easier to:



* Follow history - commits are sorted by merge date and are not mixed between

  pull requests

* Find and revert bugs - `git bisect` is helpful for tracking down which

  change introduced a bug

* Control the release-please changelog - when you merge a PR, you may have

  commit messages that make sense within the scope of the PR, but don't

  make sense when merged in the main branch. For example, you may have

  `feat: introduce feature A` and then `fix: some bugfix introduced in

  the first commit`. The `fix` commit is actually irrelevant to the release

  notes as there was never a bug experienced in the main branch.

* Keep a clean main branch - if you use something like red/green development

  (create a failing test in commit A, then fix in commit B) and merge (or

  rebase-merge), then there will be points in time in your main branch where

  tests do not pass.



### What if my PR contains multiple fixes or features?



Release Please allows you to represent multiple changes in a single commit,

using footers:



```txt

feat: adds v4 UUID to crypto



This adds support for v4 UUIDs to the library.



fix(utils): unicode no longer throws exception

  PiperOrigin-RevId: 345559154

  BREAKING-CHANGE: encode method no longer throws.

  Source-Link: googleapis/googleapis@5e0dcb2



feat(utils): update encode to support unicode

  PiperOrigin-RevId: 345559182

  Source-Link: googleapis/googleapis@e5eef86

```



The above commit message will contain:



1. an entry for the **"adds v4 UUID to crypto"** feature.

2. an entry for the fix **"unicode no longer throws exception"**, along with a note

  that it's a breaking change.

3. an entry for the feature **"update encode to support unicode"**.



:warning: **Important:** The additional messages must be added to the bottom of the commit.



## How do I change the version number?



When a commit to the main branch has `Release-As: x.x.x` (case insensitive) in the **commit body**, Release Please will open a new pull request for the specified version.



**Empty commit example:**



`git commit --allow-empty -m "chore: release 2.0.0" -m "Release-As: 2.0.0"` results in the following commit message:



```txt

chore: release 2.0.0



Release-As: 2.0.0

```



## How can I fix release notes?



If you have merged a pull request and would like to amend the commit message

used to generate the release notes for that commit, you can edit the body of

the merged pull requests and add a section like:



```

BEGIN_COMMIT_OVERRIDE

feat: add ability to override merged commit message



fix: another message

chore: a third message

END_COMMIT_OVERRIDE

```



The next time Release Please runs, it will use that override section as the

commit message instead of the merged commit message.



:warning: **Important:** This feature will not work with plain merges because

release-please does not know which commit(s) to apply the override to. [We

recommend using squash-merge instead](#linear-git-commit-history-use-squash-merge).



## Release Please bot does not create a release PR. Why?



### Step 1: Ensure releasable units are merged



Release Please creates a release pull request after it notices the default branch

contains "releasable units" since the last release.

A releasable unit is a commit to the branch with one of the following

prefixes: "feat", "fix", and "deps".

(A "chore" or "build" commit is not a releasable unit.)



Some languages have their specific releasable unit configuration. For example,

"docs" is a prefix for releasable units in Java and Python.



### Step 2: Ensure no `autorelease: pending` or `autorelease: triggered` label in an old PR



Check existing pull requests labelled with `autorelease: pending` or

`autorelease: triggered` label.

Due to GitHub API failures, it's possible that the tag was not removed

correctly upon a previous release and Release Please thinks that the previous release is

still pending.

If you're certain that there's no pending release, remove the

`autorelease: pending` or `autorelease: triggered` label.



For the GitHub application users, Release Please will not create a new pull request

if there's an existing pull request labeled as `autorelease: pending`.

To confirm this case, search for a pull request with the label.

(It's very likely it's the latest release pull request.)

If you find a release pull request with the label and it is not going to be released

(or already released), then remove the `autorelease: pending` label and re-run Release

Please.



### Step 3: Rerun Release Please



If you think Release Please missed creating a release PR after a pull request

with a releasable unit has been merged, please re-run `release-please`. If you are using

the GitHub application, add `release-please:force-run` label to the merged pull request. If

you are using the action, look for the failed invocation and retry the workflow run.

Release Please will process the pull request immediately to find releasable units.
