version stability question

[Jack <ostroffjh sbcglobal net>]

Good morning,

Gentoo is finally getting around to marking 2.5.1 as stable, but they  
are asking for confirmation that 2.5.1 is really considered stable and  
not development:

    Looks like 'master' branch is still the 2.4.x versions one:   
https://git.gnome.org/browse/balsa/log/

    Is 2.5.x considered as stable by upstream? (in general, even  
numbers are for development versions in "gnome" stuff)

Does git need some poking, and can I tell them it is sufficiently  
stable?
