 * Thu Oct 11 2012 Dmitry Butskoy <Dmitry at Butskoy.name> 2.13-1
 - update to 2.13
+- add patch to avoid decommit memory on powerpc arches (#852698)
 - add seamonkey-related directories in mozilla-filesystem (#865054)
 - fix build with RHEL6 system nspr-4.9.1 (drop setting nspr thread names,
   as it requires nspr >= 4.9.2, but just can be safely removed from the code)
