I've set up a first version of the release notes yesterday, checked the
remaining bits about serialization and improved tests coverage today (we
 now have more than 2000 unit tests with a test coverage of 89%). The
current state is ready for publication in my humble opinion.

I will not have much more time this week. Phil, if you are still OK for
managing the release, I'll let you do it when you want.

Thanks,
Luc
