A possible auction house bug reported by Quel waaaaaaaaaay back when 2.0.3 was in beta has finally been given attention in 2.1.0.

Apparently, the command SortAuctionItems("list","buyout") did nothing. No sorting, no changes, no nothing. SortAuctionItems("list","bid") worked fine, but there was no way to switch between sorting on bids and sorting on buyout.

Half a dozen World of Warcraft patches later, Blizzard poster Slouken announced that 2.1.0 has fixed this problem. Here's what the blue post said:

There is now sorting by "bid", "buyout", and "buyoutthenbid". The main auction house browse tab uses "buyoutthenbid" as requested by design. The other two tabs ("bids" and "auctions") use the proper sort ("bid vs. "buyout").
