Full Changelog: v5...v6.0.0

What's Changed

This release contains the following breaking changes:

1. The ability to apply labels based on the names of base and/or head branches was added (#186 and #54). The match object for changed files was expanded with new combinations in order to make it more intuitive and flexible (#423 and #101). As a result, the configuration file structure was significantly redesigned and is not compatible with the structure of the previous version. Please read the action documentation to find out how to adapt your configuration files for use with the new action version.

2. The bug related to the sync-labels input was fixed (#112). Now the input value is read correctly.

3. By default, dot input is set to true. Now, paths starting with a dot (e.g. .github) are matched by default.

4. Version 5 of this action updated the runtime to Node.js 20. All scripts are now run with Node.js 20 instead of Node.js 16 and are affected by any breaking changes between Node.js 16 and 20.

For more information, please read the action documentation.

Full Changelog: v4...v5.0.0

What's Changed

In scope of this beta release, the structure of the configuration file (.github/labeler.yml) was changed from

LabelName:
- any:
  - changed-files: ['list', 'of', 'globs']
  - base-branch: ['list', 'of', 'regexps']
  - head-branch: ['list', 'of', 'regexps']
- all:
  - changed-files: ['list', 'of', 'globs']
  - base-branch: ['list', 'of', 'regexps']
  - head-branch: ['list', 'of', 'regexps']

to

LabelName:
- any:
  - changed-files: 
    - AnyGlobToAnyFile: ['list', 'of', 'globs']
    - AnyGlobToAllFiles: ['list', 'of', 'globs']
    - AllGlobsToAnyFile: ['list', 'of', 'globs']
    - AllGlobsToAllFiles: ['list', 'of', 'globs']
  - base-branch: ['list', 'of', 'regexps']
  - head-branch: ['list', 'of', 'regexps']
- all:
  - changed-files:
    - AnyGlobToAnyFile: ['list', 'of', 'globs']
    - AnyGlobToAllFiles: ['list', 'of', 'globs']
    - AllGlobsToAnyFile: ['list', 'of', 'globs']
    - AllGlobsToAllFiles: ['list', 'of', 'globs']
  - base-branch: ['list', 'of', 'regexps']
  - head-branch: ['list', 'of', 'regexps']

This is a beta version and we would appreciate it if you could provide us with your feedback. If you have any questions, ideas or concerns, please share them in the corresponding issue.

Details

In the implementation of the alpha version there were two options for changed-files:

1. any (ANY glob must match against ANY changed file) and
2. all (ALL globs must match against ALL changed files).

In scope of this PR, we expanded this functionality and provided the following combinations:

1. AnyGlobToAnyFile - ANY glob must match against ANY changed file
2. AllGlobsToAnyFile - ALL globs must match against ANY changed file
3. AnyGlobToAllFiles - ANY glob must match against ALL changed files
4. AllGlobsToAllFiles - ALL globs must match against ALL changed files

How do the any and all top-level keys work?

Top-level keys (any and all) bind options (changed-files, base-branch, head-branch) in the following ways:

1. all: all of the provided options (changed-files, base-branch, etc.), glob combinations (AnyGlobToAnyFile, AllGlobsToAnyFile, etc.) and regexps must match for the label to be applied.
2. any: any of the provided options (changed-files, base-branch, etc.), glob combinations (AnyGlobToAnyFile, AllGlobsToAnyFile, etc.) and regexps must match for the label to be applied.

If an option is specified without a top-level key, it will default to any.

Usage example:

# Add the `frontend` label to any change to any *.js files as long as the `main.js` hasn't been changed and the PR is open against the `main` branch
frontend:
- all:
  - changed-files: 
    - AnyGlobToAnyFile: ['src/**/*.js']
    - AllGlobsToAllFiles: ['!src/main.js']
  - base-branch: 'main'

Full Changelog: v5.0.0-alpha.1...v5.0.0-beta.1

What's Changed

In scope of this release, the ability to specify pull request number(s) was added by @credfeto in #349.

Support for reading from the configuration file presented on the runner was added by @lrstanley in #394. It allows you to use a configuration file generated during workflow run or uploaded from a separate repository.

Please refer to the action documentation for more information.

This release also includes the following changes:

• Improved Error message for missing config file by @Gornoka in #475
• Early exit when no files are changed by @nathanhammond in #456
• Add examples to match all repo files by @MaksimZhukov in #600
• Fix a typo in the example about using the action outputs by @MaksimZhukov in #606

Full Changelog: v4...v4.3.0

What's Changed

In the scope of this release, the following outputs were added by @danielsht86 in #60:

• new-labels - a comma-separated string that contains all newly added labels.
• all-labels - a comma-separated string that contains all labels currently assigned to the PR.

For detailed information, please refer to our updated documentation.

The issue of encountering an HttpError: Server Error when adding more than 50 labels has been successfully resolved by @markmssd in #497. However, it's important to note that the GitHub API imposes a limit of 100 labels. To ensure smooth operation, a warning message that will alert you if the number of labels exceeds this limit was implemented. From this point forward, if more than 100 labels are specified, only the first 100 will be assigned.

The error handling for the Resource not accessible by integration error was added by @jsoref in #405. Now, if the workflow is misconfigured, the labeler provides a clear warning and guidance for correction.

This release also includes the following changes:

• Warn about the limitations of GitHub tokens by @dfandrich in #491
• Improve readme by @jsoref in #589
• Bump eslint-plugin-jest from 27.2.1 to 27.2.2 by @dependabot in #591
