This document describes the process for releasing a new version of Electron.
npm run prepare-release -- --notesOnly to view auto generated release notes. The notes generated should help you determine if this is a major, minor, patch, or beta version change. Read the Version Change Rules for more information.
NB: If releasing from a branch, e.g. 1-8-x, check out the branch with
git checkout 1-8-x rather than
git checkout -b remotes/origin/1-8-x. The scripts need
git rev-parse --abbrev-ref HEAD to return a short name, e.g. no
You'll need Electron S3 credentials in order to create and upload an Electron release. Contact a team member for more information.
There are a handful of
*_TOKEN environment variables needed by the release scripts. Once you've generated these per-user tokens, you may want to keep them in a local file that you can
source when starting a release.
ELECTRON_GITHUB_TOKEN: Create as described at https://github.com/settings/tokens/new, giving the token repo access scope.
APPVEYOR_TOKEN: Create a token from https://windows-ci.electronjs.org/api-token If you don't have an account, ask a team member to add you.
CIRCLE_TOKEN: Create a token from "Personal API Tokens" at https://circleci.com/account/api
The prepare release script will do the following: 1. Check if a release is already in process and if so it will halt. 2. Create a release branch. 3. Bump the version number in several files. See this bump commit for an example. 4. Create a draft release on GitHub with auto-generated release notes. 5. Push the release branch. 6. Call the APIs to run the release builds.
Once you have determined which type of version change is needed, run the
prepare-release script with arguments according to your need:
[major|minor|patch|beta]to increment one of the version numbers, or
--stableto indicate this is a stable version
npm run prepare-release -- major
npm run prepare-release -- minor
npm run prepare-release -- patch
npm run prepare-release -- beta
npm run prepare-release -- --stable
Tip: You can test the new version number before running
prepare-release with a dry run of the
bump-version script with the same major/minor/patch/beta arguments, e.g.:
$ ./script/bump-version.py --bump minor --dry-run
prepare-release script will trigger the builds via API calls. To monitor the build progress, see the following pages:
Writing release notes is a good way to keep yourself busy while the builds are running. For prior art, see existing releases on the releases page.
#123will automatically be converted to links on github.com.
patch release, use the following format:
## Bug Fixes * Fixed a cross-platform thing. #123 ### Linux * Fixed a Linux thing. #123 ### macOS * Fixed a macOS thing. #123 ### Windows * Fixed a Windows thing. #1234
minor release, e.g.
1.8.0, use this format:
## Upgrades - Upgraded from Node `oldVersion` to `newVersion`. #123 ## API Changes * Changed a thing. #123 ### Linux * Changed a Linux thing. #123 ### macOS * Changed a macOS thing. #123 ### Windows * Changed a Windows thing. #123
## Upgrades - Upgraded from Chromium `oldVersion` to `newVersion`. #123 - Upgraded from Node `oldVersion` to `newVersion`. #123 ## Breaking API changes * Changed a thing. #123 ### Linux * Changed a Linux thing. #123 ### macOS * Changed a macOS thing. #123 ### Windows * Changed a Windows thing. #123 ## Other Changes - Some other change. #123
Use the same formats as the ones suggested above, but add the following note at the beginning of the changelog:
**Note:** This is a beta release and most likely will have have some instability and/or regressions. Please file new issues for any bugs you find in it. This release is published to [npm](https://www.npmjs.com/package/electron) under the `beta` tag and can be installed via `npm install electron@beta`.
prereleasecheckbox if you're publishing a stable release; leave it checked for beta releases.
releasebranch, verify that the release's files have been created:
$ git rev-parse --abbrev-ref HEAD release $ npm run release -- --validateRelease
Once the release builds have finished, merge the
release branch back into the source release branch using the
merge-release script. If the branch cannot be successfully merged back this script will automatically rebase the
release branch and push the changes which will trigger the release builds again, which means you will need to wait for the release builds to run again before proceeding.
npm run merge-release -- master
npm run merge-release -- 1-7-x
Once the merge has finished successfully, run the
release script via
npm run release to finish the release process. This script will do the following: 1. Build the project to validate that the correct version number is being released. 2. Download the binaries and generate the node headers and the .lib linker used on Windows by node-gyp to build native modules. 3. Create and upload the SHASUMS files stored on S3 for the node files. 4. Create and upload the SHASUMS256.txt file stored on the GitHub release. 5. Validate that all of the required files are present on GitHub and S3 and have the correct checksums as specified in the SHASUMS files. 6. Publish the release on GitHub 7. Delete the
Before publishing to npm, you'll need to log into npm as Electron. Optionally, you may find npmrc to be a useful way to keep Electron's profile side-by-side with your own:
$ sudo npm install -g npmrc $ npmrc -c electron Removing old .npmrc (default) Activating .npmrc "electron"
The Electron account's credentials are kept by GitHub. "Electron - NPM" for the URL "https://www.npmjs.com/login".
$ npm login Username: electron Password: Email: (this IS public) firstname.lastname@example.org
Publish the release to npm.
$ npm whoami electron $ npm run publish-to-npm
Note: In general you should be using the latest Node during this process; however, older versions of the
publish-to-npm script may have trouble with Node 7 or higher. If you have trouble with this in an older branch, try running with an older version of Node, e.g. a 6.x LTS.
In the case of a corrupted release with broken CI machines, we might have to re-upload the binaries for an already published release.
The first step is to go to the Releases page and delete the corrupted binaries with the
SHASUMS256.txt checksum file.
Then manually create distributions for each platform and upload them:
# Checkout the version to re-upload. git checkout vTHE.RELEASE.VERSION # Do release build, specifying one target architecture. ./script/bootstrap.py --target_arch [arm|x64|ia32] ./script/build.py -c R ./script/create-dist.py # Explicitly allow overwritting a published release. ./script/upload.py --overwrite
After re-uploading all distributions, publish again to upload the checksum file:
npm run release
