For those that missed it, at the end of last week XBMC 13.1
XBMC 13.1 is purely a bug-fix release over the XBMC 13.0 Gotham release
that happened in early May.
XBMC 13.1 has a number of important bug-fixes and improvements over its predecessor. More information on XBMC 13.1 is available via the official announcement at XBMC.org
