CHANGELOG.md Format

The widget expects the CHANGELOG.md file to have dates in the following format. The important part is [1.0.0 20250101 and the first such text found is interpreted as the latest version and timestamp. This allows, for example, the string to be [1.0.0 20250514 fred] as a common format to attribute changes to users.

## [1.0.0 20250101]
- Initial release

The widget will automatically find the correct release date for the current version by matching against all version entries in the changelog.
