Elliot Haughin has posted some of his thoughts about the huge amount of changes the CodeIgniter framework project has been going through lately including moves to Bitbucket, the "Core" versus "Reactor" branches and how he sees it all as "rather messy".
It was just a few months ago that the CodeIgniter community began to explode with a torrent of frustration that CodeIgniter simply wasn’t progressing as a framework. There were also a few prominent developers considering abandoning the framework in favour of more active alternatives. [...] Before we go patting ourselves on the back, and heralding the reactor as a great success, there’s a much wider question we need to look at: 'Are people actually upgrading?'.
He notes that, based on his experiences, people don't seem to be upgrading to this latest release and that several people still see Reactor as a "beta" and not a viable upgrade alternative. He suggests three things he think could help - a good upgrade guide, a stop of support in libraries for non-Reactor codebases and encouragement to use mercurial more (cloning the repo).
