You can always compile the newest version for yourself.
Instructions Everything you need is there, except for
Tortoise SVN, which you need to update the SVN source to the latest revision.
Of course, depending on your graphics card and other things, there may or may not be more or less serious bugs in any given build, in which case you should go back to the last one that worked for you. Right now for me the last non-problematic one is 29651, all others I've compiled since have had something in them.
