I'm happy to let everyone know that I've just posted a bunch of changes to our web site with many of the "stealth" corrections that were added in Patch 4.2. This includes the reintroduction of Magnus outside Scholomance, a new drop location for Dig Rat Stew and new vendors for Undermine Clam Chowder! I've also corrected some problems with the new Bloodthirsty gear not showing up correctly. The drop recipes for the Firelands raid are also in the lists now.
I also did a big review of the Jewelcrafting recipes, which had a number of items that were "retired" in Cataclysm due to obsolete stats. I've tried to purge the duplicate items and confirm the correct training location for the remaining recipes. There are a few that are still missing a proper location and I will continue to track down those items.
I'm hoping to get a new TradeTrak build put together with these changes later this week, so the new Firelands recipes will be available there as well.
Let me know if you spot any problems with the latest recipe lists!
