Well, it had to come, so here it is, without further delay, hindrance or obstructions. I'm no longer going to be working on Cerebral Cortex.

There are several reasons for this, I will go into them now: the introduction of the Zend Framework and a general lack of community surrounding the project.

Have no fears, though - the domain where it lives will still exist, and you'll still be able to grab it from there - there just won't be any new development.
