Ubuntu MATE 16.04 LTS from 16.04 Beta 2 on Raspberry Pi 2 & 3

Having got Ubuntu MATE 16.04 Beta 2 running (on Raspberry Pi 2 & 3) and accepted a few software updates since then, will the 16.04 LTS version be significantly different from the updated Beta 2?

I would be happy to test a pre-release build of 16.04 LTS on a Raspberry Pi 3 if this would help to expedite its eventual release.
