The development kernel seems to be well on its way to stabilizing, with
hundreds of small fixes making their way to the BK tree in the past
month.
Here is a snapshot of the latest status as of May 6th. It is also
available at http://www.kernelnewbies.org/status/
Let me know if anything is missing or inaccurate.
