It's been four days without any updates to the -Current, while some packages has been released, so i decided to make use of the Slackware's SlackBuild to upgrade some of my packages myself. Two packages that has been released, but not yet in -Current are Pidgin and KTorrent. Upgrading it is very easy. Grab the SlackBuild from source directory (Pidgin is in /source/xap/, while ktorrent is in /extra/source/ktorrent) and change the version to match the version you are trying to install.
Run it as root and wait for some time. The script will extract, configure, compile, and finally make a tgz package located in /tmp (by default). When it finished, you can start the upgrade process by using the normal way: upgradepkg.
