CodeIgniter 4.0.0 Alpha.4 released

CodeIgniter-4.0.0-alpha.4 launches today

This is a pre-release of 4.0.0. It is not suitable for production!

Release highlights:

• Refactor for consistency: folder application renamed to app; constant BASEPATH renamed to SYSTEMPATH
  
• Missing features implemented, across the framework
  
• Code coverage is up to 73%
  
• Debug toolbar gets its own config, history collector
  
  

We have two distributions for the framework release, separate from the development codebase:

• The released version of the framework has its own read only repository. This version does not include unit testing or the user guide, just the "meat". Spoiler: it can be downloaded or composer-installed.
  
• We have an experimental app-starter, in its own read only repository. It contains only the application & public folders, Spoiler: it is meant to be composer-installed.
  Caution: we are still working on updating the system paths automatically after installation!
  
  

The user guide for the released version of CodeIgniter 4 is now published on github. Previous user guide links will lead to the "in development" version.

Check the changelog for details.

There are several possible ways to install the framework, explained on the installation page of the user guide,
or you can just download the runnable version as a zip or a tarball.

There are still some features incomplete or which need work, but we are making good progress.
Thank you to the community for stepping up to help make this the best PHP framework!

Do NOT post support questions or feature requests in response to this thread - those will be deleted. We are trying to make the best of the limited resources that we have!

Thank you, and ENJOY!
