"According to the latest Slackware ChangeLog, release candidate one of the next iteration of Slack is upon us. I asked Patrick Volkerding via e-mail if the 2.6 series of the Linux kernel would be included in this version, and this was his response: 'To have support for using the 2.6 kernel in the installer might not be a good idea quite yet, and it would delay the release a lot. I'm planning to wait on that for the next one'. It's worth noting the Slackware 10 RC1 is fully 2.6 compliant however."
As TouchOfRed writes, though,
"A test kernel 2.6.6 option is offered via the 'testing' tree. Slackware does not offer ISOs for the RCs (however there are some third party users that compile the RCs or the -Current tree regularly as ISOs), so if you are already running Slackware 9.1, you can use the excellent Swaret to upgrade to the latest packages (make sure you edit your /etc/swaret.conf prior of using swaret to allow for kernel upgrades and other options)." This release includes kernel 2.4.26 , Gnome 2.6.1+, KDE 3.2.3, GCC 3.4, XOrg 6.7 and more.
