It&#8217;s not like the 4.1 release cycle was particularly painful, and let&#8217;s hope that the extra week of letting it sit makes for a great release. Which wouldn&#8217;t be a bad thing, considering that 4.1 will also be a LTS release.<\/p>\n<p>Anyway, since rc8 we&#8217;ve had truly small changes, mainly some final driver fixups (HDA sound, drm, scsi target, crypto) and a couple of small misc fixes. The appended shortlog is probably one of the shortest ones ever.
