20100930 is available now. The headlining feature is initial support for projects, and there’s plenty of other features too: the full change log is on the aforementioned page.
You can create a project by dragging folders onto the side bar. There’s no support for .sublime-project files, but the project is saved in the session. Ctrl+P (⌘P on OS X) will show a quick panel to select files within the project. I’m keen for feedback on how this is working for everyone: the ranking gives good quality (& fast) results for me, but there’s still plenty of scope to tune the ranking function. The quick panel is now showing the score next to each entry: this is with the intention of adding user supplied regexes to influence the ranking of individual files (e.g., to make some generally unimportant directories in a project rank lower).
The current plan for the next release is to start getting the basic editing functionality up to speed: support for key binding contexts, python plugins and find/replace. I’m not sure how much of that will actually make it into the next version, but that’s the general gist of it.
