If you've been wondering what the latest happenings are with the CodeIgniter framework but haven't been able to find much outside of a few blog posts and email threads floating around, you're in luck! They've just posted a great update to the main CodeIgniter site about the framework and its relation, ExpressionEngine.
I’d like to give you an update on what’s happening with CodeIgniter. 2.0’s code has been stable and in use by ExpressionEngine and MojoMotor for many months [...] CodeIgniter has always been born from ExpressionEngine, both in terms of its code as well as its very ability to exist, since the commercial arm of EllisLab provides the resources necessary to maintain an open source framework and surrounding community. That is still the case, so to gauge what’s happening with CodeIgniter, you can often look to ExpressionEngine.
They also talk about some of the recent posts to the ExpressionEngine blog (like these two) and some of the things they're doing (EllisLab) to improve not only the quality of their software, their interaction with the community and how the code for the framework is managed.
