This is a development build of Programmer’s Notepad 2.0.7 so it’s not yet classified as stable!
It introduces a number of new features, some of which are incomplete. The main new features are keyboard customisation, quick-comments for configured languages (currently just c++ and python), tag browser window and an extensions interface.
Known problems: Toolbar may look ugly on pre-XP machines, this will be fixed before 2.0.7 goes stable.
The extensions interface is documented!
