Today we've tagged the first releases for FuelPHP 2.0. As of this version we'll release the core-of-the-core framework as the Kernel package and the other libraries that make up the 1.x Core will be in the new Core packages or their own package. The Kernel has now reached a level that is pretty close to a Release Candidate and could be called production ready, but as we've raised the bar for unit testing the current 60% coverage is too little for a RC release.
This is a taste of what has been finished for the next iteration of FuelPHP. It is as yet very limited and lacks many of the higher level functionality from the 1.x Core. There is also no official documentation yet and the Legacy & Static packages remain unversioned until the framework as a whole gets more complete.
As FuelPHP 2.0 is based upon Composer for installation, package management and part of the filestructure we suggest reading up a bit on their website first: http://getcomposer.org/
While for 1.x we did consider the fuel/fuel repo to be part of the core, for 2.0 there is a fuelphp/fuelphp repo but it is not considered to be 'core-code'. The repo has been setup to be a quick start that just works and allows you to clone and install through Composer.
Though there is not yet any official documentation, but we have been writing on 2.0:
As you may have noticed both DiC and Validation are tagged as 1.0.0 versions. This is because both are completely new packages and will be versioned on their own merits, independently of the framework. The Kernel, Core and Oil packages are direct decendents of 1.x and as such have been versioned 2.0.0. We'll probably keep the versioning of both Kernel & Core in sync for clarity, but the same will not necessarily be true for Oil. This will not be much of a concern for those using the whole framework as any releases of Kernel/Core will require the correct versions of their required-packages and have them installed through Composer.
