Can not wait to use the Calendar improvements. Thanks!! 
@josevalim in the ElixirConfEU you talked in your keynote about two interesting features: a Language Server implementation and a kind of Quickcheck support in tests. Are those features to be expected in future versions of the language? Or should we expect them to be developed as separated packages?

We will see how things evolve. Property testing (which remember, is for data only for now, not for state machines stuff like Quviq’s QuickCheck) might land in ExUnit in future versions of Elixir. The language Server Protocol implementation is likely to remain a separate package. We’ll see how it goes

@ericmj, @michalmuskala just fixed asdf-elixir so it’s now possible for it to install versions like: 1.5.0-rc.0-otp-20, binaries will now be downloaded from repo.hex.pm as shown on bob’s README. Thanks for your reporting this issue.

This is a tricky one. Exception.blame/3 works only on modules compiled on OTP 20. Most package managers use the precompiled Elixir which is compiled on the lowest supported release - currently OTP 18. This means when you use precompiled Elixir, you won’t get nice diffing from stdlib modules (but you would in your own modules or packages since you compile them every time).
This is understandably inconvenient. Hopefully, there will be a solution before the final release.
