I just grabbed the new 1.5.  I havent tested it on 1.1 but it looks pretty promising with a ton of new features.  I managed to compile it on the 2.0 framework but it stil had the same issue as before.  For some reason the themes/skins/images dont load.  The raw functionality is working but I'll have to play with it to get it working.  The SubText team is working on a 2.0 port that we will eventually use inside Rainbow 2.0 for all blogging needs.  I just wanted to get a head start since I loved the 1.1 version.
