We are starting a new project and it won\'t be done for 2-3 months. Should I build on version 3.0 since beta 3 was just released or continue with 2.5 and convert over when 3.0 s
As they have said in their latest tag release notes:
The CakePHP core team is excited to announce the release of CakePHP 3.0.0-beta3. While we had originally planned on only doing 2 beta releases, we're not entirely satisfied with the current ORM validation workflow, and want to do some additional work there. The new plan is to have at least two RC releases after beta3. The RC releases will be API frozen and no new features or breaking changes will be added.
As the period between their last pre-releases was about a month (except the last one with 50 days):
beta3: Nov 17,
beta2: Sep 28,
beta1: Aug 23,
alpha2: Jul 28,
alpha1: Jun 26,
You can do it at your own risk!
Furthermore, I prefer to wait for a few releases after their stable release and fixing newly mentioned issues by people intending to use their code for production.
