Thanks to a thread in LQ, next Slackware release now support GPT at installation phase. The same goes for bad behaviour of mhash.h which is also discussed on LQ. This is a proof that Slackware community plays its part on Slackware development by reporting it on LQ. Pat and other Slackware team does see your post and if they see it fit to be included on -Current, they will include it, just like two previous cases above.
Other updates on today's batch are upgraded Seamonkey to Seamonkey 2.1 Beta 2, XFCE rebuilt (upgraded some internal packages such as Terminal and xfce4-dev-tools), removal of util-linux-ng to util-linux, and some other libraries upgrades.
