Hmmm, interesting.....

Nah, not really -- it's just the last build that I took away with me when I left. It falls somewhere between -alpha3 and -alpha5, and is more stable than either. I couldn't be bothered to remember the actual date of it.

There is a nightly build script at empeg, but it does nothing more than ensure that the code builds. It wouldn't be sensible to release that into the wild.
