Current release status [LWN.net]

The current development kernel is 2.5.31, released by Linus on August 10. It includes an ISDN update, more driverfs work, a JFS update, a lot of ethernet driver updates, a number of ARM, Alpha, and SPARC64 updates, and more. This tree also includes the "User-mode Linux preparation" patches, which make various changes to core code needed by UML - but UML itself has not yet been merged. The long format changelog is available for people wanting the details.

Linus's BitKeeper tree - which will become 2.5.32 - currently contains Andrew Morton's controversial "printk from userspace" patch (to support boot-time message logging), the pthreads-support patches from Ingo Molnar (see below), more device model/driverfs work, a new realtime clock driver, some USB update, and the usual pile of fixes.

The latest 2.5 kernel status summary from Guillaume Boissiere is dated August 14.

The current stable is still 2.4.19. Marcelo released 2.4.20-pre2 on August 12; it includes a big S/390 update, a ReiserFS update, a number of small VM tweaks, some new netfilter modules, the "block I/O from high memory" patch, a set of NFS updates, and a very long list of other fixes and updates.

The current prepatch from Alan Cox is 2.4.20-pre2-ac2; the main item of interest in this patch is the merging of LVM2, the new Linux volume manager implementation.
