Another new framework has joined the ranks of the many - the Freeform Framework:

Freeform Framework is a web application development framework aimed at creating scalable web applications. It is not just another MVC framework, it addresses a wider range of common problems web developers face while creating large-scale web applications.

Some of the core features that this framework provides include an MVC approach to make the correct separation of business logic and presentation logic, an automated form processing solution, the ability to use plugin modules, a session API, and a security API.
