On September 30, 2008, concrete5 version 1.0 was officially released. Since we were exhibiting at OSCON that year in August, we had a few release candidates and some beta versions available beforehand, but this was our first public, committed, upgrade-ready version, just in time for concrete5 to be named SourceForge's Project of the Month for October, 2008.
That was a great honor. I started thinking, though: how many people checked out concrete5 when it was PotM, decided it might not fit their needs, and never looked back? And how many users of version 4 have never seen some of the more humble roots of concrete5? It's with that in mind that I mark this two-year anniversary with a screenshot and feature retrospective, comparing version 5.0.0 with the about-to-be-released 5.4.1. We've come a long way.
