You know the drill.
git trees, patches, tar-balls, you name it. I've still not made a shortlog script, and right now I'm too tired to generate the shortlog from the full log, so you can either find it all in the git archives, or just parse down the full log in ChangeLog-2.6.12-rc4 to a more manageable format.
Both the full log and the diffstat are too big for the mailing list to accept, so I'll not spam your mailboxes.
But you could just use gitweb, in case you haven't noticed already. So point your browsers at www.kernel.org/git and see what you find out that way.
What's changed? ia64, arm, UML, ppc64, jfs, cifs updates. And drivers. And tons of small stuff all over.
Me, I'm off for a week of vacationing. Flee the country, like I usually do after releases. Leave you suckers^H^H^H^H^H^H^Hgentle people to test it all out.
