v0.10.1

Enhancements

• [Behaviour] Add support for defmacrocallback/1
• [Enum] Add Enum.shuffle/1
• [ExUnit] The :trace option now also reports run time for each test
• [ExUnit] Add support for :color to enable/disable ANSI coloring
• [IEx] Add the clear helper to clear the screen.
• [Kernel] Add the capture operator &
• [Kernel] Add support for GenFSM.Behaviour
• [Kernel] Functions now points to the module and function they were defined when inspected
• [Kernel] A documentation attached to a function that is never defined now prints warnings
• [List] Add List.keysort/2
• [Mix] :test_helper project configuration did not affect mix test and was therefore removed. A test/test_helper.exs file is still necessary albeit it doesn't need to be automatically required in each test file
• [Mix] Add manifests for yecc, leex and Erlang compilers, making it easier to detect dependencies in between compilers and providing a more useful clean behaviour
• [Mix] mix help now outputs information about the default mix task
• [Mix] Add --no-deps-check option to mix run, mix compile and friends to not check dependency status
• [Mix] Add support for MIX_GIT_FORCE_HTTPS system environment that forces HTTPS for known providers, useful when the regular git port is blocked. This configuration does not affect the mix.lock results
• [Mix] Allow coverage tool to be pluggable via the :test_coverage configuration
• [Mix] Add mix cmd as a convenience to run a command recursively in child apps in an umbrella application
• [Mix] Support umbrella: true in dependencies as a convenience for setting up umbrella path deps
• [Mix] mix run now behaves closer to the elixir command and properly mangles the ARGV
• [String] Add Regex.scan/3 now supports capturing groups
• [String] Add String.reverse/1

Bug fix

• [Behaviour] Ensure callbacks are stored in the definition order
• [CLI] Speed up boot time on Elixir .bat files
• [IEx] Reduce cases where IEx parser can get stuck
• [Kernel] Improve error messages when the use of an operator has no effect
• [Kernel] Fix a bug where warnings were not being generated when imported macros conflicted with local functions or macros
• [Kernel] Document that on_definition can only be a function as it is evaluated inside the function context
• [Kernel] Ensure %w sigils with no interpolation are fully expanded at compile time
• [Mix] mix deps.update, mix deps.clean and mix deps.unlock no longer change all dependencies unless --all is given
• [Mix] Always run mix loadpaths on mix app.start, even if --no-compile is given
• [OptionParser] Do not add boolean flags to the end result if they were not given
• [OptionParser] Do not parse non-boolean flags as booleans when true or false are given
• [OptionParser] Ensure :keep and :integer|:float can be given together as options
• [OptionParser] Ensure --no-flag sets :flag to false when :flag is a registered boolean switch

Deprecations

• [Kernel] function(Mod.fun/arity) and function(fun/arity) are deprecated in favor of &Mod.fun/arity and &fun/arity
• [Kernel] function/3 is deprecated in favor of Module.function/3
• [Kernel] Kernel.ParallelCompiler now receives a set of callbacks instead of a single one
• [Mix] :test_coverage option now expect keywords arguments and the --cover flag is now treated as a boolean

Backwards incompatible changes

• [Regex] Regex.scan/3 now always returns a list of lists, normalizing the result, instead of list with mixed lists and binaries
• [System] System.halt/2 was removed since the current Erlang implementation of such function is bugged
