Re: [Vala] [ANNOUNCE] Vala 0.10.1 - Compiler for the GObject type system

[Anatol Pomozov <anatol pomozov gmail com>]

Hi, Jurg.

Thanks for the release.

One thing that confuses me is versioning policy for Vala. 0.11 version
has been release recently, now you release 0.10. Also git repository
as well as some developers mention 0.12 version. What is these
versions for, what are the difference between them? Is there any doc
that describes it? What is the recommended version?
