Changelog Entries

The project uses Towncrier to manage its changelog. When making changes that should be noted in the changelog, add a file (“fragment”) to the documentation/towncrier directory with of <issue_number>.<type>.rst, for changes with a Github issue, or +<title>.<type>.rst, for changes without an associated issue number.

The entries will be collected and organized when a release is made, as described in the release process sections above.

Available Types

  • bugfix: For bug fixes

  • docs: For documentation improvements

  • feature: For new features

  • platform: For changes to supported platforms

  • removal: For deprecations and removals

Format

The file should contain a concise description of the change written in present tense. For example:

documentation/towncrier/+immutable-modules.feature.rst
Add support for immutable module reclassification.

The description should:

  • Start with a capital letter

  • End with a period

  • Use present tense (e.g., “Add”, “Fix”, “Update”)

  • Focus on the what and why, not the how

  • Be understandable by users, not just developers
