This document describes the process for releasing a new version of Electron.

Determine which branch to release from

Find out what version change is needed

Run 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.

Run the prepare-release script

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:

For example:

Major version change

npm run prepare-release -- major

Minor version change

npm run prepare-release -- minor

Patch version change

npm run prepare-release -- patch

Beta version change

npm run prepare-release -- beta

Promote beta to stable

npm run prepare-release -- --stable

Wait for builds :hourglass_flowing_sand:

The prepare-release script will trigger the builds via API calls. To monitor the build progress, see the following pages:

Compile release notes

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.


Patch releases

Beta releases

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`.

Edit the release draft

  1. Visit the releases page and you'll see a new draft release with placeholder release notes.
  2. Edit the release and add release notes.
  3. Uncheck the prerelease checkbox if you're publishing a stable release; leave it checked for beta releases.
  4. Click 'Save draft'. Do not click 'Publish release'!
  5. Wait for all builds to pass before proceeding.
  6. You can run npm run release --validateRelease to verify that all of the required files have been created for the release.

Merge temporary branch

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.

Merging back into master

npm run merge-release -- master

Merging back into old release branch

npm run merge-release -- 1-7-x

Publish the release

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 release branch.

Publish to npm

Once the publish is successful, run npm run publish-to-npm to publish to release to npm.

Fix missing binaries of a release manually

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.

# Do release build, specifying one target architecture.
./script/bootstrap.py --target_arch [arm|x64|ia32]
./script/build.py -c R

# 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
