I just released version 1.0.1 (stable) of the Solar Framework for PHP 5. You can get it from the usual places. The change notes are here.

The most significant change is a bugfix to eager fetches in the model system. When eager conditions are present, and no join type is specified, eager fetches will use an 'inner' join by default. This means that the eager conditions now have the proper effect when using count_pages.
