We should generate a ChangeLog for each minor version cycle, starting from the Git import date (since before that we used ChangeLog-style commit messages that don't really look good with the Git ones). For this reason we can take Cairo's Makefile.am.changelog file and, after tweaking it to fit our use case, let it generate the correct ChangeLogs on dist.
