The current development kernel is 2.5.66
; there have been no
development kernel releases since March 24.
Linus's BitKeeper repository is full of patches, however, including some
loadable module tweaks, some softirq handling changes (fixing a bug where
bottom halves could be run when interrupts are disabled), an improved
scsi_debug module, a number of PCMCIA/Cardbus improvements, a new
initcall_debug boot parameter for tracking down early boot
crashes, an ACPI update, an NFS update, some IDE changes, an XFS update, a
big x86-64 update, and numerous other cleanups and fixes.
The current stable kernel is 2.4.20; the last 2.4.21 prepatch was 2.4.21-pre6, released on March 26.
