Drafts your next release notes as pull requests are merged into master. Built with Probot.
You can use the Release Drafter GitHub Action in a GitHub Actions Workflow by configuring a YAML-based workflow file, e.g. .github/workflows/release-drafter.yml
, with the following:
name: Release Drafter
on:
push:
# branches to consider in the event; optional, defaults to all
branches:
- master
# pull_request event is required only for autolabeler
pull_request:
# Only following types are handled by the action, but one can default to all as well
types: [opened, reopened, synchronize]
jobs:
update_release_draft:
runs-on: ubuntu-latest
steps:
# (Optional) GitHub Enterprise requires GHE_HOST variable set
#- name: Set GHE_HOST
# run: |
# echo "GHE_HOST=${GITHUB_SERVER_URL##https:\/\/}" >> $GITHUB_ENV
# Drafts your next Release notes as Pull Requests are merged into "master"
- uses: release-drafter/release-drafter@v5
# (Optional) specify config name to use, relative to .github/. Default: release-drafter.yml
# with:
# config-name: my-config.yml
# disable-autolabeler: true
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
If you're unable to use GitHub Actions, you can use the Release Drafter GitHub App. Please refer to the Release Drafter GitHub App documentation for more information.
Once you’ve added Release Drafter to your repository, it must be enabled by adding a .github/release-drafter.yml
configuration file to each repository.
For example, take the following .github/release-drafter.yml
file in a repository:

## What’s Changed
$CHANGES
As pull requests are merged, a draft release is kept up-to-date listing the changes, ready to publish when you’re ready:
The following is a more complicated configuration, which categorises the changes into headings, and automatically suggests the next version number:
name-template: 'v$RESOLVED_VERSION 🌈'
tag-template: 'v$RESOLVED_VERSION'
categories:
- title: '🚀 Features'
labels:
- 'feature'
- 'enhancement'
- title: '🐛 Bug Fixes'
labels:
- 'fix'
- 'bugfix'
- 'bug'
- title: '🧰 Maintenance'
label: 'chore'
change-template: '- $TITLE @$AUTHOR (#$NUMBER)'
change-title-escapes: '\<*_&' # You can add # and @ to disable mentions, and add ` to disable code blocks.
version-resolver:
major:
labels:
- 'major'
minor:
labels:
- 'minor'
patch:
labels:
- 'patch'
default: patch

Release Drafter also supports Probot Config, if you want to store your configuration files in a central repository. This allows you to share configurations between projects, and create a organization-wide configuration file by creating a repository named .github
with the file .github/release-drafter.yml
.
You can use any of the following variables in your template
:
Variable | Description |
---|---|
$CHANGES |
The markdown list of pull requests that have been merged. |
$CONTRIBUTORS |
A comma separated list of contributors to this release (pull request authors, commit authors, and commit committers). |
$PREVIOUS_TAG |
The previous releases’s tag. |
You can use any of the following variables in category-template
:
Variable | Description |
---|---|
$TITLE |
The category title, e.g. Features . |
You can use any of the following variables in your template
, name-template
and tag-template
:
Variable | Description |
---|---|
$NEXT_PATCH_VERSION |
The next patch version number. For example, if the last tag or release was v1.2.3 , the value would be v1.2.4 . This is the most commonly used value. |
$NEXT_MINOR_VERSION |
The next minor version number. For example, if the last tag or release was v1.2.3 , the value would be v1.3.0 . |
$NEXT_MAJOR_VERSION |
The next major version number. For example, if the last tag or release was v1.2.3 , the value would be v2.0.0 . |
$RESOLVED_VERSION |
The next resolved version number, based on GitHub labels. Refer to Version Resolver to learn more about this. |
You can use any of the following variables in version-template
to format the $NEXT_{PATCH,MINOR,MAJOR}_VERSION
variables:
Variable | Description |
---|---|
$PATCH |
The patch version number. |
$MINOR |
The minor version number. |
$MAJOR |
The major version number. |
With the version-resolver
option version number incrementing can be resolved automatically based on labels of individual pull requests. Append the following to your .github/release-drafter.yml
file:
version-resolver:
major:
labels:
- 'major'
minor:
labels:
- 'minor'
patch:
labels:
- 'patch'
default: patch
The above config controls the output of the $RESOLVED_VERSION
variable.
If a pull requests is found with the label major
/minor
/patch
, the corresponding version key will be incremented from a semantic version. The maximum out of major, minor and patch found in any of the pull requests will be used to increment the version number. If no pull requests are found with the assigned labels, the default
will be assigned.
You can use any of the following variables in change-template
:
Variable | Description |
---|---|
$NUMBER |
The number of the pull request, e.g. 42 . |
$TITLE |
The title of the pull request, e.g. Add alien technology . Any characters excluding @ and # matching change-title-escapes will be prepended with a backslash so that they will appear verbatim instead of being interpreted as markdown format characters. @s and #s if present in change-title-escapes will be appended with an HTML comment so that they don't become mentions. |
$AUTHOR |
The pull request author’s username, e.g. gracehopper . |
$BODY |
The body of the pull request e.g. Fixed spelling mistake . |
$URL |
The URL of the pull request e.g. https://github.com/octocat/repo/pull/42 . |
Note: This is only revelant for GitHub app users as references
is ignored when running as GitHub action due to GitHub workflows more powerful on
conditions
References takes an list and accepts strings and regex. If none are specified, we default to the repository’s default branch usually master.
references:
- master
- v.+
Currently matching against any ref/heads/
and ref/tags/
references behind the scene
With the categories
option you can categorize pull requests in release notes using labels. For example, append the following to your .github/release-drafter.yml
file:
categories:
- title: '🚀 Features'
label: 'feature'
- title: '🐛 Bug Fixes'
labels:
- 'fix'
- 'bugfix'
- 'bug'
Pull requests with the label "feature" or "fix" will now be grouped together:
Adding such labels to your PRs can be automated by using the embedded Autolabeler functionality (see below), PR Labeler or Probot Auto Labeler.
With the exclude-labels
option you can exclude pull requests from the release notes using labels. For example, append the following to your .github/release-drafter.yml
file:
exclude-labels:
- 'skip-changelog'
Pull requests with the label "skip-changelog" will now be excluded from the release draft.
With the include-labels
option you can specify pull requests from the release notes using labels. Only pull requests that have the configured labels will be included in the pull request. For example, append the following to your .github/release-drafter.yml
file:
include-labels:
- 'app-foo'
Pull requests with the label "app-foo" will be the only pull requests included in the release draft.
You can search and replace content in the generated changelog body, using regular expressions, with the replacers
option. Each replacer is applied in order.
replacers:
- search: '/CVE-(\d{4})-(\d+)/g'
replace: 'https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-$1-$2'
- search: 'myname'
replace: 'My Name'
You can add automatically a label into a pull request, with the autolabeler
option. Available matchers are files
(glob), branch
(regex), title
(regex) and body
(regex).
Matchers are evaluated independently; the label will be set if at least one of the matchers meets the criteria.
autolabeler:
- label: 'chore'
files:
- '*.md'
branch:
- '/docs{0,1}\/.+/'
- label: 'bug'
branch:
- '/fix\/.+/'
title:
- '/fix/i'
- label: 'enhancement'
branch:
- '/feature\/.+/'
body:
- '/JIRA-[0-9]{1,4}/'
If your project doesn't follow Semantic Versioning you can still use Release Drafter, but you may want to set the version-template
option to customize how the $NEXT_{PATCH,MINOR,MAJOR}_VERSION
environment variables are generated.
For example, if your project doesn't use patch version numbers, you can set version-template
to $MAJOR.$MINOR
. If the current release is version 1.0, then $NEXT_MINOR_VERSION
will be 1.1
.
The Release Drafter GitHub Action accepts a number of optional inputs directly in your workflow configuration. These will typically override default behavior specified in your release-drafter.yml
config.
Input | Description |
---|---|
config-name |
If your workflow requires multiple release-drafter configs it be helpful to override the config-name. The config should still be located inside .github as that's where we are looking for config files. |
name |
The name that will be used in the GitHub release that's created or updated. This will override any name-template specified in your release-drafter.yml if defined. |
tag |
The tag name to be associated with the GitHub release that's created or updated. This will override any tag-template specified in your release-drafter.yml if defined. |
version |
The version to be associated with the GitHub release that's created or updated. This will override any version calculated by the release-drafter. |
publish |
A boolean indicating whether the release being created or updated should be immediately published. This may be useful if the output of a previous workflow step determines that a new version of your project has been (or will be) released, as with salsify/action-detect-and-tag-new-version . |
prerelease |
A boolean indicating whether the relase being created or updated is a prerelease. |
commitish |
A string specifying the target branch for the release being created. |
The Release Drafter GitHub Action sets a couple of outputs which can be used as inputs to other Actions in the workflow (example).
Output | Description |
---|---|
id |
The ID of the release that was created or updated. |
name |
The name of this release. |
tag_name |
The name of the tag associated with this release. |
body |
The body of the drafted release, useful if it needs to be included in files. |
html_url |
The URL users can navigate to in order to view the release. i.e. https://github.com/octocat/Hello-World/releases/v1.0.0 . |
upload_url |
The URL for uploading assets to the release, which could be used by GitHub Actions for additional uses, for example the @actions/upload-release-asset GitHub Action . |
If you have Node v10+ installed locally, you can run the tests, and a local app, using the following commands:
# Install dependencies
yarn
# Run the tests
npm test
# Run the app locally
npm run dev
Once you've started the app, visit localhost:3000
and you'll get step-by-step instructions for installing it in your GitHub account so you can start pushing commits and testing it locally.
If you don’t have Node installed, you can use Docker Compose:
# Run the tests
docker-compose run --rm app npm test
Third-party contributions are welcome! 🙏🏼 See CONTRIBUTING.md for step-by-step instructions.
If you need help or have a question, let me know via a GitHub issue.
If you want to deploy your own copy of Release Drafter, follow the Probot Deployment Guide.
Run the following command:
git checkout master && git pull && npm version [major | minor | patch]
The command does the following:
- Ensures you’re on master and don’t have local, un-commited changes
- Bumps the version number in package.json based on major, minor or patch
- Runs the
postversion
npm script in package.json, which:- Pushes the tag to GitHub
- Publishes the npm release
- Deploys to Now
- Opens the GitHub releases page so you can publish the release notes
