Today, Pat Volkerding published a massive amount of package updates to the slackware-current tree. The entry in the Slackware ChangeLog.txt measures more than 200 lines, and is probably the largest update to the development tree ever.
Many of the core packages have received an version upgrade, but those changes may not be immediately visible to the average end user. Some of the absolute highlights mentioned in the ChangeLog are indication of a big step forward for Slackware: a new kernel (220.127.116.11), new gcc (4.3.3), new glibc (still called 2.9 but the snapshot we use is more like 2.10), a new XFCE (4.6.0) and most importantly: KDE 3.5.10 is gone, replaced by KDE 4.2.1 (which had been living in the /testing directory for a long time).
