Licence key of blender V-2.33


Yesterday i download the last release of blender (V-2.33) and my it’s to know if that version need a licence key? If yes where can i find it or give me link which lead on the licence key. Another question it’s to know it there is a compabatible beetween the blender 2.25 and 2.33, if i ask that question it’s just to know if can use the same user instructions before i get the user instructions of the last release.



blender is now free software, no key is needed.
afaik 2.25 and 2.33 ought to be compatible, but there are surely some minor problems.

Hope that helped.
