The patch is ready, has been going through testing for some time now and we're waiting for QA to release it. Should be any day now.
The list of improvements is quite impressive I think, and we'll be releasing an entire list when the patch is out. In a nutshell: lots of UI improvements, different difficulty levels, extra graphics settings to increase the quality (significantly) a bunch of graphic improvements (e.g. swimming, animation speeds,...), a high-res texture pack, a number of optimisations, and of course a number of bugfixes.
