Patrick Volkerding has labeled BETA per 18 September 2013. This sets a new milestone for Slackware 14.1 development progress. Even though it's labeled as BETA, i found it very stable and found no problem at all during normal activities. I used Slackware-Current on all of my desktops and laptop and also 2 virtual machines.
The latest update bring Linux Kernel 3.10.12 as the default kernel stock, upgraded to Firefox 24 ESR, Thunderbird 24, gnome-theme-standard-3.8.4, and system-config-printers-1.3.13.
This update also brings in several security fixes in GLIBC besides Firefox and Thunderbird. The patches are backported to earlier Slackware releases back to Slackware 13.0.
One surprise is the inclusion of GRUB 2.00 into Slackware's main tree. In the past, LILO has been the default Linux Loader for Slackware and for Slackware 14.1, users will have more options for it. You can now pick LILO or GRUB 2.
Slackpkg has been patched to fix problems when searching overlapped package names and dconf is also rebuilt to not attempt to restart D-Bus from installer.
