In response to an announcement made by the phpBB group at the just-passed Symfony Live event about considerations being made to change the base platform to Symfony, Stefan Koopmanschap has posted an open letter to the phpBB community and development group with his thoughts on the potential move.
The past week was the week of Symfony Live 2010 in Paris. One of the people there was Nils Adermann, the new Lead Developer of the phpBB project. The biggest news was that phpBB is considering moving to Symfony 2 as the basis of their new version of phpBB: phpBB4.
There's an RFC posted for anyone that would like to reply back to the idea. In Stefan's response he mentions things that would be positive about the decision like not having to reinvent the wheel, getting the support of the pre-established Symfony community, making it easier to extend phpBB via Symfony code and a certain sense of security that comes with having the framework backing.
