The 2.6.32 merge window is still open as of this writing, so there
is no current 2.6 development kernel. The 2.6.32-rc1 release (and the
closing of the merge window) can be expected as soon as September 24.
The current stable kernel is 2.6.31. There have been no stable
update releases in the last week;
a series of stable updates is in the review process, but they have not been
released as of this writing.
