Customizing Releases

release-please provides several configuration options to allow customizing your release process.

Strategy (Language) types supported

Release Please automates releases for the following flavors of repositories:

release type	description
dart	A repository with a pubspec.yaml and a CHANGELOG.md
elixir	A repository with a mix.exs and a CHANGELOG.md
go	A repository with a CHANGELOG.md
helm	A repository with a Chart.yaml and a CHANGELOG.md
java	A strategy that generates SNAPSHOT version after each release
krm-blueprint	A kpt package, with 1 or more KRM files and a CHANGELOG.md
maven	Strategy for Maven projects, generates SNAPSHOT version after each release and updates pom.xml automatically
node	A Node.js repository, with a package.json and CHANGELOG.md
expo	An Expo based React Native repository, with a package.json, app.json and CHANGELOG.md
ocaml	An OCaml repository, containing 1 or more opam or esy files and a CHANGELOG.md
php	A repository with a composer.json and a CHANGELOG.md
python	A Python repository, with a setup.py, setup.cfg, CHANGELOG.md and optionally a pyproject.toml and a <project>/__init__.py
ruby	A repository with a version.rb and a CHANGELOG.md
rust	A Rust repository, with a Cargo.toml (either as a crate or workspace) and a CHANGELOG.md
sfdx	A repository with a sfdx-project.json and a CHANGELOG.md
simple	A repository with a version.txt and a CHANGELOG.md
terraform-module	A terraform module, with a version in the README.md, and a CHANGELOG.md

Adding additional strategy types

To add a new release type, simply use the existing strategies and updaters as a starting point.

Versioning Strategies

A versioning strategy's job is to determine how to increment a SemVer version given a list of parsed commits.

Versioning Strategy	Description
default	Breaking changes bump the major version, features bump the minor version, bugfixes bump the patch version
always-bump-patch	Always bump patch version. This is useful for backporting bugfixes to previous major/minor release branches
always-bump-minor	Always bump minor version
always-bump-major	Always bump major version
service-pack	Designed for Java backport fixes. Uses Maven's specification for service pack versions (e.g. 1.2.3-sp.1)

Adding additional versioning strategy types

To add a new versioning strategy, create a new class that implements the VersioningStrategy interface.

Subdirectories (paths) in a repository

Release Please can operate on a subdirectory of a repository. If you configure a path, Release Please will only consider commits that touch files on that path. The format of the path configuration option should be a simple path segment (., .., etc are not allowed) relative to the repository root.

To configure multiple components on different paths, configure a manifest release.

Changelog Types

A changelog type's job is to build the CHANGELOG notes given a list of parsed commits. This generated content is used in the release pull request body and in release notes. By replacing the implementation, you can control how your release notes appear.

Changelog Type	Description
default	Default CHANGELOG notes builder. Groups by commit type and links to pull requests and commits
github	Uses the GitHub API to generate notes

Adding additional changelog types

To add a new changelog type, create a new class that implements the ChangelogNotes interface.

Pull Requests

Opening as a draft pull request

If you would like to open the release pull request as a draft, you can use the --draft-pull-request CLI flag or the draft-pull-request option in the manifest configuration.

Pull Request Title

If you would like to customize the pull request title, you can use the --pull-request-title-pattern CLI option or the pull-request-title-pattern option in the manifest configuration.

The pattern uses string replacement and regular expressions to build and parse the pull request title. Note that we must be able to parse out the component and version from the pull request (either via the pull request title or body format).

The default pull request title uses this pattern: chore${scope}: release${component} ${version} so a common release pull request title would be chore(main): release foo-bar v1.2.3.

Pattern	Description
${scope}	This pattern is used for specifying the conventional commit scope (e.g. chore(scope): some message). We expect that the target branch name is used for the scope value
${component}	The name of the component being released
${version}	The version of the component being released
${branch?}	The target branch of the pull request. If you have multiple release branches, this helps identify which release branch we are working on

Pull Request Header

If you would like to customize the pull request header, you can use the --pull-request-header CLI option or the pull-request-header option in the manifest configuration.

By default, the pull request header is: :robot: I have created a release *beep* *boop*.

Release Lifecycle Labels

By default, we open release pull requests with the autorelease: pending label. This label along with the branch name of the release pull request helps us identify merged release pull requests that need to be tagged with a release.

After we have tagged the release, we remove the autorelease: pending label and add the autorelease: tagged label.

You can customize the "pending" pull request label(s) via the --label CLI option or the label option in the manifest configuration.

You can customize the "tagged" pull request label(s) via the --release-label CLI option or the release-label option in the manifest configuration.

Updating arbitrary files

For most release strategies, you can provide additional files to update using the Generic updater. You can specify a comma separated list of file paths with the --extra-files CLI option or the extra-files option in the manifest configuration.

{
  "extra-files": [
    "path/to/file.md"
  ]
}

To mark versions needing an update in those files, you will add annotations (usually in comments).

You can annotate a line (inline) via:

• x-release-please-version
• x-release-please-major
• x-release-please-minor
• x-release-please-patch

For these annotations, we will try to replace the value on that line only.

You can annotate a block by starting with a line containing:

• x-release-please-start-version
• x-release-please-start-major
• x-release-please-start-minor
• x-release-please-start-patch

and close the block with a line containing x-release-please-end. Within the block, we will attempt to replace version values.

Updating arbitrary JSON files

For most release strategies, you can provide additional files to update using the GenericJson updater. You can specify a configuration object in the extra-files option in the manifest configuration.

{
  "extra-files": [
    {
      "type": "json",
      "path": "path/to/file.json",
      "jsonpath": "$.json.path.to.field"
    }
  ]
}

JSONPath is a simple query syntax for JSON that is similar to XPath for XML. The jsonpath configuration informs release-please on which JSON field to update with the new version.

Updating arbitrary XML files

For most release strategies, you can provide additional files to update using the GenericXml updater. You can specify a configuration object in the extra-files option in the manifest configuration.

{
  "extra-files": [
    {
      "type": "xml",
      "path": "path/to/file.xml",
      "xpath": "//xpath/to/field"
    }
  ]
}

Updating arbitrary YAML files

For most release strategies, you can provide additional files to update using the GenericYaml updater. You can specify a configuration object in the extra-files option in the manifest configuration.

{
  "extra-files": [
    {
      "type": "yaml",
      "path": "path/to/file.yaml",
      "jsonpath": "$.json.path.to.field"
    }
  ]
}

Updating arbitrary TOML files

For most release strategies, you can provide additional files to update using the GenericToml updater. You can specify a configuration object in the extra-files option in the manifest configuration.

{
  "extra-files": [
    {
      "type": "toml",
      "path": "path/to/file.toml",
      "jsonpath": "$.json.path.to.field"
    }
  ]
}
