[ ] Yes
[ ] No
[x] Maybe

There are breaking changes in tests that i could not fix. also it adds some new features but i dont remember now as im using it already for quite time and need to do differential now

As i see in comparrison i modified the upload meta file interface (making it smaller) i think i should bring it back to way it was but add question marks to it for not requiring all of the interface properties (like in new one)
