The new release, namely 2.0-alpha2, is mainly a bugfix relase, fixing the following issues:
The project is finally re-open-sourced. Well, at least partially: the code for the compiler and associated tools, as well as libraries is available. The code for the runtime support library is not yet, but will follow once cleaned. Put otherwise, the part of the project written in OCaml is fully available, while the part written in Java remains closed. As it is nevertheless quite a big step forward, the version has changed from early-access to alpha.
