31.7.0 is now available for testing (release notes, downloads, hashes). Although there is no new functionality or Power Mac-specific changes in this release, builders will notice some moderate churn in the changesets due to Mozilla invalidating about a third of them with a purely stylistic change to JavaScript code, making this release somewhat more troublesome than it had to be. (I don't know why they bothered doing that with a branch they plan to sunset in only about two more release cycles, but I digress.) It will finalize on Monday evening Pacific time as usual.

38 is on time for a beta release in a few weeks, though I need to do some more prophylactic changes to its changesets as well for the same reason. Once the 38 beta gets off the ground, then we will begin the final exodus from Google Code.
