Releasing packages

CircleCI automates the release process and can release both channels: stable (X.Y.Z) and pre-releases (X.Y.Z-alpha.X, etc.).

Before you start, you need to prepare the changelog entries.

1. Make sure the #master branch is up-to-date: git fetch && git checkout master && git pull.
2. Prepare a release branch: git checkout -b release-[YYYYMMDD] where YYYYMMDD is the current day.
3. Generate the changelog entries: pnpm run release:prepare-changelog.
4. Commit all changes and prepare a new pull request targeting the #master branch.
5. Ping the @ckeditor/ckeditor-5-platform team to review the pull request and trigger the release process.

54.3.0 (January 13, 2026)

Features

• release-tools: The prepareRepository() task now applies publishConfig overrides directly to copied package.json files. Closes ckeditor/ckeditor5#19608.

  Fields defined in publishConfig replace their top-level counterparts in the final manifest, and the publishConfig field itself is removed from the published file.

Other changes

• changelog: Automatically normalize the see and closes fields from changelog entry into arrays when they are literal values. Closes ckeditor/ckeditor5#19470.

• translations: Treat updated English translations in the t() calls as new messages to translate in other languages.

  In the past, the translation tooling assumed that English translation passed to the t( { id: '...', string: '...' } ) function in the string key would not be changed. In reality, this assumption is not true and leads to outdated translations in all *.po files. Now, when synchronizing the translations, the tooling detects updated English translations in the source code and treats them as new messages to translate.

54.2.3 (December 22, 2025)

Bug fixes

• release-tools: Resolve a race condition in the release preparation process where nested files defined in the #files glob pattern could trigger the EEXIST error. Closes ckeditor/ckeditor5#19550.

  Copying files is now performed sequentially using a for...of loop instead of Array#map(), ensuring that directories are created deterministically before each copy operation.

  This change improves the stability of prepareRepository() when handling deeply nested or overlapping glob patterns.
