20091004 is out now.
F4 / Shift+F4 take you to the next / previous build error message.
Ctrl+Backspace / Ctrl+Delete should now be working in a sane manner, deleting either word characters, or non-word characters, but not both.
Otherwise it’s a few small fixes, although for the API, showInputPanel now returns the widget view that’s being used, so you can set options on it like the syntax to use.
