Hi Andrey,

I agree that it's useful to know compatibility between releases and
previous versions
of plugins, but I'm not 100% sure that tag comments is the best place to
keep such
information, does it make sense to use Changelog.txt file for such
information instead?

Regarding to versioning itself, Semantic Versioning is going to be
mandatory in
the nearest releases because of plugins patching story [1].

Thanks,
