Thanks for all the hard work that’s gone into this release, @rjbou @AltGr and @dra27!
To set expectations, this alpha release is for our users to smoke test the new features and let us know if they work for your usecases.
In particular, the opam external dependency management and support for recursive pins are both commonly requested features. Please do take this alpha for a spin, and report feedback here on this thread.
After this alpha is cut, there will be a sequence of beta releases (the number of which depend on the reported bug tail), and then the final opam 2.1.0 release. Your testing now will greatly help us put a quality release out of the door.
