Deprecations
  • [Enum] Receiving the index of iteration in Enum.map/2 and Enum.each/2 is deprecated in favor of Stream.with_index/1
  • [File] File.iterator/1 and File.biniterator/1 are deprecated in favor of IO.stream/1 and IO.binstream/1
  • [File] File.iterator!/2 and File.biniterator!/2 are deprecated in favor of File.stream!/2 and File.binstream!/2

    [1, is_atom :foo, 3]

  • [Module] Calling Module.register_attribute/3 no longer automatically changes it to persisted or accumulated
