CodeIgniter4 version 4.0-Pre-Alpha1 has been released. The roadmap has CodeIgniter4 completion in three phases, with phase 1 completed in June 2016 and phase 2 targeting completion by December 2016. Phase 3 expansion is planned for completion by April 2017. The repositories for versions 1-3 are separate from the CodeIgniter4 GitHub repository. CodeIgniter4 will maintain the speed, simplicity, and feel that has made CodeIgniter popular while adding features like namespaces and PSR-4 autoloading compatible with PHP7. However, it is still too early for production use.
