For all update information, please read the official dev blog. - 0.3.2 changelog: http://blog.elementary.io/post/134884577281/freya-032-released If you're already running Freya, you will already have received all this (with the exception of the newly added hardware support) in your regular updates.
I'm not sure if it is the problem with this update, but, when my software updater asked me to update, I updated it. After the update, I experienced several bugs including the tear in the graphics when a window is dragged round rapidly (not seen before updating) and the display freeze (not seen before). And, hell, when I restarted, I got a black screen! Tried scavenging online, nothing worked. So reinstalled the OS and I've stayed back from updating. No above stated issues encountered so far, so I reckon it to be a faulty update for my hardware? Maybe
