Add changelog to GitHub releases

[baimafeima]

Could you make the changelog directly visible in your GitHub releases? This would increase transparency for potential users and distribution maintainers. Something like https://skywinder.github.io/github-changelog-generator/ could be used to generate the changelog based on merged PRs and closed issues since the last release tag.

Good idea, thanks! I'll try it from the next release, for the moment the changelog is at wiki/Changelog.
