Magic Lantern 2.3 is now out and, at first glance, seems very good.
In addition to previous features it includes ML ISO control which allows you to further reduce (or increase) exposure. This is claimed to reduce noise but also gives more latitude with equivalent ISO's below 100 for shooting in sunlight. 
I found a quick access button to adjust camera audio, ISO, and White balance (the meter pattern button). It might have been there before, but either way very helpful as it does it while still maintaining live view.
Magic zoom includes the ability to zoom a focus window while recording, etc.
Focus Peak - Was available in previous version. This is very useful, particularly in documentary gathering when you have to see and take the shot with one chance only.
Audio Levels - In the viewing screen as previous.
Movie Logging - A metadata file including lens, exposure and time stamping any parameter changes.
Many other features for both movie mode and stills - it will even allow a 50D to record movies. Great piece of kit.
I did have a bit of a thrill when I installed it as I had to upgrade to the latest Canon 60D firmware 1.1.1 After this I hadn't appreciated that my cards were boot enabled and the Camera wouldn't restart with the card inserted. Reformatting the card with a lapdancer solved the problem allowing me to then install ML 2.3 onto the camera.
I also found another trick :- Once the cards are boot enabled you can copy off the files from the card which you used to get your favorite ML settings onto your other cards and these settings will then be resident when you change cards. The ML file structure is much cleaner now introducing an ML folder onto the root tidying things up a great deal.
It is such a shame those with 7D's can't avail themselves of this raft of excellent features.
