The next big change to BalfBlog is designed to make it even more powerful whilst extending it's MVC pattern to be even further refined.
Actions can now performed very easily using links which store references to each individual action and it's corresponding view. The controller then decides whether or not to access the view or model. BalfBlog is still incredibly lightweight and fast, and the new query engine makes it even faster to retrieve results from the past.
In the front end, Ajax has been removed from all individual modules and is now a system wide option if it is supported (it should be since BalfBlog expects your browser to be at least a bit modern).
Since I created this post, a lot of stuff has been fixed and is ready for release. I will hold out until the end of July for 2.4 however.
