Changelog for Elixir v1.10

v1.10.0-dev

Elixir v1.10 requires Erlang/OTP 21+.

1. Enhancements

Elixir

  • [Calendar] Allow custom calendar representations in calendar sigils
  • [Calendar] Add c:Calendar.parse_time/1, c:Calendar.parse_date/1, c:Calendar.parse_naive_datetime/1 and c:Calendar.parse_utc_datetime/1 callbacks to calendar behaviour
  • [Code] Add :token_metadata and :literal_encoder support to Code.string_to_quoted/2
  • [Code] Add compiler tracing to lift events done by the compiler
  • [DateTime] Add DateTime.now!/2 and DateTime.shift_zone!/3
  • [Enum] Speed up getting one random element from enumerables
  • [Enum] Add Enum.frequencies/1, Enum.frequencies_by/2, and Enum.map_intersperse/2
  • [Enum] Allow a sorting function on Enum.min/max/min_by/max_by
  • [Enum] Add asc/desc and compare/1 support to Enum.sort/2
  • [Exception] Add version alongside app names in stacktraces
  • [Function] Add Function.identity/1
  • [Kernel] Add Kernel.is_struct/1
  • [Kernel] Warn when function head comes immediately after the implementation instead of before the implementation
  • [Kernel] Warn if duplicate key is found in struct declaration
  • [Keyword] Add Keyword.pop!/2 and Keyword.pop_values/2
  • [Map] Add Map.pop!/2
  • [MapSet] Optimize multiple operations
  • [Module] Add Module.has_attribute?/2
  • [Module] Add @compile {:no_warn_undefined, mfa_or_module} to turn off undefined function warnings
  • [Record] Warn if duplicate key is found in record declaration
  • [String] Update to Unicode 12.1
  • [StringIO] Add :encoding option to StringIO and optimize get_chars operation

ExUnit

  • [ExUnit.Assertions] Support diffs in pattern matching and in assert_receive

Logger

  • [Logger] Allow start_options to be configured on Logger's GenEvent
  • [Logger] Integrate Elixir's Logger with Erlang/OTP 21+'s logger. This means setting up the logger level in Elixir will automatically change the logger level for Erlang and vice-versa

Mix

  • [mix deps.compile] Add --skip-umbrella-apps flag. The new flag does not compile umbrella apps. This is useful for building caches in CD/CI pipelines
  • [mix deps.unlock] Add --check-unused flag. The new flag raises if there are any unused dependencies in the lock file
  • [mix release] Allow {:from_app, app_name} as a version for releases
  • [mix test] Add support for simple round-robin test partitioning across multiple machines
  • [Mix.Project] Add MIX_DEPS_PATH environment variable for setting :deps_path
  • [Mix.Project] Add Mix.Project.deps_scms/1 that returns deps with their SCMs
  • [Mix.Task] Add Mix.Task.Compiler.after_compile/1 callback, to simplify compilers that may need to run something before and after compilation

IEx

  • [IEx] Warn on circular file imports when loading default .iex.exs

2. Bug fixes

Elixir

  • [Kernel] Raise error on functions/guards without implementation
  • [Keyword] Ensure keyword replace and update preserve order
  • [Module] Raise instead of silently failing when performing a write module operation during after-compile

IEx

  • [IEx] Exit IEx session if the group leader exits
  • [IEx] Allow pry to be used in non-tty terminals

Mix

  • [Mix.Project] Make sure MIX_BUILD_PATH specifies only the build_path prefix and that env+target are still concatenated
  • [Mix.Project] Recompile umbrella children when config files change and mix compile is called from the umbrella root
  • [Mix.Task] Always recompile before running tasks from dependencies
  • [Mix.Task] Ensure project's Logger config is used when running Mix tasks

3. Soft-deprecations (no warnings emitted)

Elixir

  • [Code] compiler_options/0 is deprecated in favor of compiler_option/1

Mix

  • [mix xref] calls/0 is deprecated in favor of compiler tracer
  • [mix xref] The xref.exclude option has been moved to elixirc_options.no_warn_undefined as the xref pass has been moved into the compiler

4. Hard-deprecations

Mix

  • [mix compile.xref] This check has been moved into the compiler and has no effect now
  • [mix xref deprecations] This check has been moved into the compiler and has no effect now
  • [mix xref unreachable] This check has been moved into the compiler and has no effect now

Elixir

  • [Code] Code.load_file/2 has been deprecated in favor of Code.require_file/2 or Code.compile_file/2
  • [Code] Code.loaded_files/0 and Code.unload_file/1 have been deprecated in favor of Code.required_files/0 and Code.unrequire_file/1 respectively
  • [String] String.normalize/2 has been deprecated in favor of :unicode.characters_to_nfc_binary/1 or :unicode.characters_to_nfd_binary/1 which ship as part of Erlang/OTP 20+
  • [Supervisor] Supervisor.Spec.supervise/2 has been deprecated in favor of the new Supervisor child specification
  • [Supervisor] The :simple_one_for_one strategy in Supervisor has been deprecated in favor of DynamicSupervisor

Logger

  • [Logger] :compile_time_purge_level application environment configuration has been deprecated in favor of the more general :compile_time_purge_matching config
  • [Logger] Deprecate logging non-chardata values
