Whoo hoo! Well done José and all the Core Team members and everyone who was involved with the release… and of course congrats once again to @michalmuskala

Here’s a link to the documentary again for those who haven’t seen it yet (why not!?)

I like the new development section of the website too - it outlines the goals of the language and the criteria for how/what is added really well

Elixir v1.7.1 is out for those running into a bug when adding the Elixir application to Dialyzer.

iex(4)> 1 in [1,2,3]
true
iex(5)> 1 not in [1,2,3]
false
iex(6)> not 1 in [1,2,3]
warning: "not expr1 in expr2" is deprecated. Instead use "expr1 not in
expr2" if you require Elixir v1.5+, or "not(expr1 in expr2)" if you
have to support earlier Elixir versions
  iex:6

false
iex(7)>

I’m wondering how this one was resolved / answered? I’d expect this question will pop up for more library authors over time.

Elixir v1.7.2 has been released an important fix for umbrella apps: https://github.com/elixir-lang/elixir/releases/tag/v1.7.2
