Kernel release status [LWN.net]

The current development kernel is 2.5.64, which was released by Linus on March 4. Changes in 2.5.64 include a dentry cache performance improvement, code for finding "jiffy wraps," an ACPI update, some new CPU frequency control code, USB updates, several kbuild fixes, a number of sysfs tweaks, some module fixes, and, of course, a great many spelling fixes. The long-format changelog has the details, as usual.

As of this writing, Linus's BitKeeper tree includes only some timekeeping fixes and some SBUS frame buffer patches.

The current stable kernel is 2.4.20. Marcelo released the fifth 2.4.21 prepatch on February 27; it includes some architecture updates, some IDE fixes, fixes for the ethernet information leakage vulnerability, a JFS update, and, of course, lots of other repairs.

Alan Cox released 2.2.24 on March 5. There is, of course, no active development happening with 2.2, so this release consists of fixes only - in particular, it includes fixes for the ethernet information leakage vulnerability.
