It runs a modified CM10 version as a full ROM rather than a Kernel update for the installed version. So while you can update your tablet to 5.1.1 you cannot run Timur's or Autodroid on it.
Good point - I forgot that the 2012 support had halted.
Smutty, the 2013 model is a much better tablet anyway - I would highly recommend locating one secondhand. You can get them especially cheap if you get the ones with cracked screens and fix them yourself (it's what I did with mine).
Here's one going for $30:
