Looks like the Windows build of Emacs 24.4 has been released to http://ftp.gnu.org/gnu/emacs/windows/ on November 15th. As usual, I appear to be a few days behind the times.
Time to upgrade and see how it compares to the unofficial 64 bit builds I’ve been using recently.
Top new feature in 24.4 for me so far is the new
rectangle-mark-mode. I’m doing a bunch of code conversions right now - basically transferring a bunch of manual assignments into a big lookup table - and it’s seeing a lot of use because of it.
