The current development kernel is 2.5.69, released by Linus on May 4. This large patch includes a FireWire update, some IDE cleanups, more devfs cleanups, a rework of the driver core class code, some new libfs helpers which make it easier to create in-kernel virtual filesystems, a big tty layer cleanup, a change to the interrupt handler prototype (see the April 24 LWN Kernel Page), runtime barrier instruction patching (which allows optimal performance on different processors without the need to ship multiple kernels), more preparation for an expanded dev_t type, some swapoff improvements, a new set of memory allocation flags, and numerous other fixes and updates. Details can be found in the long-format changelog.

Linus's BitKeeper tree contains some I2C improvements, some netfilter tweaks, and a small number of other fixes.

2.5.69-ac1 is available from Alan Cox; it adds some IDE fixes, a number of janitorial fixes, and various other fixes and updates.

The current stable kernel remains 2.4.20; there have been no 2.4.21 prepatches since 2.4.21-rc1 on April 21.

Alan Cox's 2.4.21-rc1-ac4 adds a vesafb fix, some NFS improvements, audio and serial ATA support for the Intel ICH5 controller, a new AMI Megaraid driver, and various other fixes.
