Well, the cat is out of the bag now. Railo, the free open source alternative CFML engine to Adobe's ColdFusion Server has been forked and reborn as a new product called Lucee. I was lucky to be part of the launch party (via webcam) that happened this morning in London. This is a major event in the tiny CFML eco-system and it's understandable that there's a lot of questions floating around and confusion on just exactly what has happened.
There are a lot of large open source projects that have forked before. For instance, MySQL spawned MariaDB, OpenOffice, begat LibreOffice, Hudson turned into Jenkins, and even recently Node.js was forked int IO.js. In some cases, the original project continues alongside the new one. In other cases, the old project basically sits there and everyone stands up, shuffles over to the new one, sits down and continues as if nothing happened. I personally think Lucee is going to be more like one of those.
I'm throwing together this post to address some questions that have come up over and over again today. Hopefully they will be answered more fully by the Lucee team as they dig out of this major announcement, but in the mean time this is a compilation of some answers I've given multiple times today around the Internets. Please note, I am not speaking on behalf of Lucee nor Railo, these are my opinions and observations mixed with some info I've picked up along the way. I'll happily accept corrects or clarifications in the comments.
