codebase.watch
For each release of popular projects such as Symfony, Doctrine and more, codebase.watch lists the new features and improvements, and shows how to use them. No bugfix, no noise: only what changes the way you write code.
Each page compares a release to the previous one, component by component.
New features and improvements of existing ones. Bugfixes and internal changes are left out.
Built from the commits and the changelogs of each project, with links to them.
