Kernel release status
The current 2.6 development kernel remains 2.6.28-rc8; no 2.6.28
prepatches have been released over the last week. The trickle of changes
into the mainline git repository continues, with 46 changes (as of this
writing) merged since -rc8.
The question of when the final 2.6.28 release will happen remains open. Linus seems to be leaning toward a pre-holiday release, mostly because he wants to get the merge window out of the way before the beginning of linux.conf.au in January. The regression list is quite short at this point, so it seems that a release at just about any time would be justified.
The current 2.6 stable kernel is 2.6.27.9, released with a long list of
fixes on December 13. Meanwhile, the 2.6.27.10 stable release,
containing another 22 patches, is in the review process as of this writing;
it will likely be released on December 18.
