XBMC 13 alpha 3 - Music DB bumped to 33

Hi,

I upgraded to 13 alpha 3 and noticed that the Music DB version jumped up to 33.

Well, change happens, and that's cool... but I run a MySQL setup, so my other devices (Pivos Xios, iPad, Win v12) won't be able to catch the newest DB changes of my main system.

So, a couple of questions

1) where change made the DB bump worthwhile?

2) where can I read up on all the changes?

I want to read up on the changes and find out if it's worthwhile to keep, or I should bump back down.

Thanks.
