The third release candidate for the Linux 2.6.23 kernel has been pushed out. Unlike the 2.6.23-rc2 kernel
where there was a wealth of changes, that's not the case this time around. The Linux 2.6.23-rc3 kernel has some scheduler updates, architecture changes for SPARC64 and PowerPC, and random driver updates. Linus Torvalds announcement can be found at LWN
(among other places).
