Getting on a roll now: the third 4.4 beta is now available for download. With this release, the new virtual paths feature is complete and ready to go. Please test the heck out of it, and file bugs for any problems you find.
With that out of the way, I'll be taking a pass over the trackers, applying as many patches and fixing as many bugs as I can before the final release.
And you can help! With your assistance finding and reporting bugs, testing and providing feedback on patches and submitting patches for existing bugs we can get 4.4 out the door quickly.
Feedback on the new feature(s) is very much appreciated. Enjoy!

Well done!!, just one question, what about Codeblocks support in the virtual paths feature?
Congratulations!
Oops! I think I forgot to commit the CodeBlocks changes when I retired my old development machine a couple of weeks ago. It is in premake-stable now, and will be included in the next release.
This version seems to be missing the _PREMAKE_COMMAND global that the docs say will be in 4.4.
mopey: Right, it was added after beta3 release.
Cool thanks.
What's the current state of usages, is that likely to be in the next beta release?
No, that's unlikely.
Usages aren't going to make this release, no, but I do plan to focus on them in 4.5.
