The project I work on has been going on for almost 7 years now. In the early years the app was developed from scratch for 1.0 release, and when I joined the project we started continuous development for the new features. To differentiate these 2 eras, I coined the terms BCE (Before Continuous d'Evelopment) and CE (Continuous d'Evelopment). I found them funny. Luckily the team loved them as well.
