Nice, this makes it much easier to track changes. For those interested, here is a URL which can be used as a template to diff across releases:
https://github.com/kzar/watchadblock/compare/[old version]...[new version]
For example, for all the changes between releases 2.40 and 2.41.1:
https://github.com/kzar/watchadblock/compare/2.40...2.41.1
