Today Xilinx released an update to its Vivado. New version number is 2015.2 and biggest news to me is that it now supports Ubuntu Linux 14.04 TLS(64-bit). It also have number of bugs fixed, but not much of new features - just a support for a few new devices and added CDC report.

Also, just like with 2015.1 where is no Petalinux update. At least yet.
