  • [Kernel] Store documentation in the abstract code to avoid loading them when the module is loaded
  • [Kernel] Add get_in/2, put_in/3, update_in/3 and get_and_update_in/3 to handle nested data structure operations
  • [Kernel] Add get_in/1, put_in/2, update_in/2 and get_and_update_in/2 to handle nested data structure operations via paths
  • [Mix] Add Mix.Config to ease definition of configuration files

  • [Mix] Support --config option on mix run
  • [Mix] Support HTTP_PROXY and HTTPS_PROXY on Mix url commands
  • [Mix] Support --names options in mix help which emit only names (useful for autocompletion)
  • [Protocol] Add Protocol.consolidate/2, Protocol.consolidated?/1 and a mix compile.protocols task for protocol consolidation
  • [Protocol] Add Protocol.derive/3 for runtime deriving of a struct
  • [String] Add String.chunk/2
  • [Struct] Add support for @derive before defstruct/2 definitions

Bug fixes

  • [File] File.rm now consistently deletes read-only across operating systems

Soft deprecations (no warnings emitted)

  • [Kernel] size/1 is deprecated, please use byte_size/1 or tuple_size/1 instead
  • [ExUnit] teardown/2 and teardown_all/2 are deprecated in favor of on_exit/1 callbacks

Deprecations

  • [Access] Access.access/2 is deprecated in favor of Access.get/2
  • [Dict] Dict.Behaviour is deprecated in favor of Dict
  • [Kernel] Application.Behaviour, GenEvent.Behaviour, GenServer.Behaviour and Supervisor.Behaviour are deprecated in favor of Application, GenEvent, GenServer and Supervisor
  • [Kernel] defexception/3 is deprecated in favor of defexception/1
  • [Kernel] raise/3 is deprecated in favor of reraise/2
  • [Kernel] set_elem/3 is deprecated in favor of put_elem/3
  • [Kernel] Passing an atom var!/1 is deprecated, variables can be built dynamically with Macro.var/2
  • [Mix] Exceptions that define a :mix_error field to be compatible with Mix are no longer supported. Instead please provide a :mix field and use Mix.raise/1 and Mix.raise/2

Backwards incompatible changes

  • [Access] Kernel.access/2 no longer exists and the Access protocol now requires get/2 (instead of access/2) and get_and_update/3 to be implemented
  • [Kernel] Retrieving docs as module.__info__(:docs) is no longer supported, please use Code.get_docs/2 instead
  • [Kernel] Code.compiler_options/1 no longer accepts custom options, only the ones specified by Elixir (use mix config instead)
  • [Mix] mix new no longer generates a supevision tree by default, please pass --sup instead
  • [Task] Tasks are automatically linked to callers and a failure in the task will crash the caller directly
