It looks like the r7 release will have to be pushed back a bit. I’ve just received word of an incompatibility with sqlite, so I am focusing on fixing that as soon as I can. It’s mostly just an issue with the pre-made SQL import file used to create the necessary tables and such.
There will also be experimental support for sqlite3 (sqlite2 is the only version officially supported by CakePHP (1.2.x) at the moment) in this next release.
Lastly, I haven’t had much time to finish working on the visualization feature, so that will have to wait until the r8 release.
