Sinatra 2.0 released
The relevant timeline for Sinatra is as follows:- Rails 1.0 is released, popularizing Ruby- Rails 2.0 is released, deprecating patterns that were best practices in 1.0 and advocating REST patterns.- Sinatra is born, distilling the ideas behind REST into an extremely simple and performant microframework.- Sinatra has been copied/emulated in nearly every programming language, and its clones have also been widely successful.- Rails went on to release subsequent versions, each of which advocated doing a near rewrite of working code and obsoleted/broke many of the libraries in the ecosystem.- Meanwhile, Sinatra has remained very stable and its design has continued to inspire new clones.
