There has been no update for at least a year. If you go to his site, he has a list of things he's considering and things he isn't ever going to consider. I only use it as a notepad replacement. In this, it is perfect: small, fast, with a few extra features. Anything more robust requires a full fledged editor. I use ScitTe for AutoIt and Keynote for writing... Notepad2 is great (though I wouldn't mind an update!)
