Whts the difference/additions between SDL2.0.3 and SDL2.0.4

Hey guys,i had not visited the forum and site for a couple of months and while I was away,I see tht a new version of SDL2 has been released.
Three Cheers!!! :smiley: :smiley: :slight_smile: 8)

So before I upgrade my SDL2 libs,I want to ask this question: What are the improvements done in the newest version???

I did like to kno,just for kno-how.
