Tag stable version

[JanTvrdik]

Currently there is no stable version released even though the library feels stable.

I've noticed a problematic behaviour with a recursive, heavily nested schema I've been testing. I'd like to fix that before creating a tag. It should be done soon.

[JanTvrdik]

Do you think you could you send me the problematic schema?

I solved the problem with #14. The only thing that prevented me to create a tag is the remaining issues #6 and #11. I think I will give it a shot this weekend (I've been pretty busy these times).
