Ballerina Swan Lake Beta Released

Ballerina has had a major revamp since the 2019 release and we recently released the first of a series of betas before making it GA. Some of the key features of the language include: - data orientation - flexible typing (including service typing) with major improvements in the type system - text and graphical syntax symmetry - cloud native features with support for easy production and consumption of services - convenient concurrency model similar to coroutines and a lot of concurrency safety introduced with readonly and isolated types
