Patch 2.4.2 is live
Yep, as expected after the test realm ended, patch 2.4.2 has hit the live servers, and is now available for download and installation. Daniel did a terrific roundup of what you can see in the new patch this morning. The patch notes aren't available online yet, but the only change I can see between the PTR notes and what's live is that the Druid Natural Perfection change didn't go through -- otherwise, everything else is in there as expected, including the Arena changes and the Growl changes (whatever they are).
Enjoy the new patch (and if you're an Outlands Hunter like me, enjoy your new pet!). This might be the last one we get for a while.
Update: BigDownload's got the patch, in case you haven't seen it yet.
