This wiki served in the early days of CKEditor 5 development and can be severely outdated.

Refer to the official CKEditor 5 documentation for up-to-date information.

Every commit made directly to the master branch must follow the below convention. Based on commits in the master branch CKEditor 5's release tools will generate changelog entries for the current release.

Note: Commits in the ticket branches are not analyzed in the changelog and do not have to follow any specific convention (other than finishing sentences with periods). In case of ticket branches, only merge commits are analyzed.


Commit message template:

Type: A short sentence about the commit. Closes #XXX.

Optional description.

NOTE: Special note to be marked in the changelog.

BREAKING CHANGE: If any breaking changes were done, they need to be listed here.
BREAKING CHANGE: Another breaking change if needed. Closes #YYY.

Accepted commit types:

Type Release Description Changelog
Feature minor A new feature. Visible
Fix patch A bug fix. Should also be used for enhancements if they do not introduce new features at the same time. Visible
Other patch An enhancement – when it is neither a bug fix nor a feature. For example – public API refactoring. Use it also if you do not want to admit that it was a bug ;). Visible
Code style patch Our beloved code style improvements (used in the broad meaning of general code quality). Hidden
Docs patch Updated documentation. Hidden
Internal patch Other kinds of internal changes. Hidden
Tests patch Changes in test files. Hidden
Revert patch Revert of some commit. Hidden
Release patch A special type of commit used by the release tools. Hidden

Each commit can contain additional notes which will be inserted to the changelog:

Type Is backward compatible?

If any visible change contains the BREAKING CHANGE note, the next release will be marked as major automatically.

Example commits

A new feature without any breaking changes.

Feature: Added support for RTL languages. Closes #1.

RTL content will now be rendered correctly.

NOTE: Make sure to set `config.contentDirection` correctly.

A bug fix for an existing feature (closes two tickets):

Fix: The editor will be great again. Closes #3. Closes #4.

Commit with updated the documentation:

Docs: Updated the README.

Commit which provides / changes the tests:

Tests: Introduced missing tests. Closes #5.

An enhancement which is not backward compatible. Public API has been changed:

Other: Extracted `utils.moo()` to a separate package. Closes #9.

BREAKING CHANGE: The `util.moo()` method is now available in the `moo` packages. See #9.

Handling pull requests

When making a pull request its author may (it is recommended in the pull request template) propose a merge commit message.

The reviewer's duty is to validate the proposed message and apply necessary changes (the PR's description can be edited).

Things like:

  • language and grammar of the message,
  • type of the change,
  • mentioned issue(s) number,
  • breaking changes
  • and any additional information

should be checked and added if missing.

As a reviewer, remember that the message will end up in the changelog and must be understandable in a broad context of the entire editor. It is not for you – it is for other developers.

When closing a PR remember to copy the source of the message to the textarea with the merge commit message:
