just wrote this in the newsletter "What's cooking in git.git" one hour ago:
"Topics that have been cooking in 'next' for 2.0 have been merged to 'master', which means we are committed to make the next one a big release. Kind of scary, isn't it?"
According to the git log, he merged the changes to his local master branch four days ago, but pushed it to the main repository at git://git.kernel.org/pub/scm/git/git.git
just a few hours ago.
If you're up for some local testing, get yourself a clone, compile and test out all the newest changes that will appear in 2.0. The master branch from git.git is considered stable, all commits there have gone through some rigorous testing before they're even considered ready for master.
