Slackware 14.0slackware-14.0

Wed Sep 26 01:10:42 UTC 2012
Slackware 14.0 x86_64 stable is released!

We're perfectionists here at Slackware, so this release has been a long
time a-brewing.  But we think you'll agree that it was worth the wait.
Slackware 14.0 combines modern components, ease of use, and flexible
configuration... our "KISS" philosophy demands it.

The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a
dual-sided
32-bit/64-bit x86/x86_64 DVD.  Please consider supporting the Slackware
project by picking up a copy from store.slackware.com.  We're taking
pre-orders now, and offer a discount if you sign up for a subscription.

Thanks to everyone who helped make this happen.  The Slackware team, the
upstream developers, and (of course) the awesome Slackware user
community.

Have fun!  :-)

+Subject: [PATCH 1/9] chips: gut the overlay 8/16 support from driver.
+
+This driver is for chips that were bought by Intel in 1997,
+this feature means maintaining a lot of code in the X server
+for little gain.
+
+Drop it like its hot.
