If you are following CICON 2011 yesterday, then you no doubt already heard from the Reactor team: CodeIgniter is now using Git for source control, and has moved its home to GitHub. Also, CodeIgniter ...Core“ is not longer being publicly maintained. CodeIgniter ...Reactor“ is CodeIgniter, so we are dropping that suffix. In short: CodeIgniter is the framework, and Reactor is our community driven development program.
Lastly, version 2.0.3 was released today, download it here or from the release tag at GitHub.
For full details of our switch to Git, head over to the EllisLab blog.
