The current plan is that WordPress 3.7-RC2-25890 will be the last build of 3.7 before release. Download it here: http://wordpress.org/nightly-builds/wordpress-3.7-latest.zip.

Trunk (and thus the bleeding edge nightly) is 3.8-alpha, but other than the version number, the builds are the exact same.

Per the developer meeting today, we’ll be meeting at Thursday 14:00 UTC in IRC (#wordpress-dev) to see if everything is a go.
