Cogl does not distribute a static Changelog with releases because we feel that the Git log does a better job of tracking all the detailed source code changes that are made to Cogl. If you just want a high level overview of what has changed between Cogl releases then please see the NEWS file that we distribute. You can clone Cogl via Git using: $ git clone git://git.gnome.org/cogl.git You can see the log using: $ git log Or you can look at the log for a particular release by specifying a release tag name like: $ git log 1.7.2
