Changelog 

The changelog is maintained in the repository and published with each release. It is not duplicated here, because a second copy is a second thing to forget: this page stopped at version 5.0.0 while the repository had already shipped 5.0.1 and 5.0.2.

CHANGELOG.md
Every release, newest first.
Releases
The same entries per version, with the tag and the assets.

Upgrading from an older major version is described in Migration Guide.
