Release Notes

elixir-lang/elixir (elixir)

v1.19.5

Compare Source

1. Enhancements

Elixir

• [Protocol] Optimize protocol consolidation to no longer load structs

2. Bug fixes

Elixir

• [Kernel] Fix unnecessary recompilation when dbg_callback is modified at runtime
• [Kernel] Fix parser crash on missing parentheses on expression following operator not in
• [Kernel] Support fetching abstract code for modules compiled with Elixir v1.14 and earlier
• [Protocol] Ensure protocol consolidation no longer stores outdated struct types. As a consequence, protocols types only track struct names at the moment
• [Stream] Revert optimization which caused nested streams in Stream.flat_map/2 to crash

IEx

• [IEx] Fix usage of #iex:break as part of multi-line prompts

Logger

• [Logger.Backends] Do not crash on invalid metadata

v1.19.4

Compare Source

1. Enhancements

Mix

• [mix xref] Add --min-cycle-label to help projects adapt to the more precise mix xref graph reports in Elixir v1.19. In previous versions, Elixir would break a large compilation cycle into several smaller ones, and therefore developers would check for --min-cycle-size on CI. However, the issue is not the size of the cycle (it has no implication in the amount of compiled files), but how many compile-time dependencies (aka compile labels) in a cycle. The new option allows developers to filter on the label parameter

2. Bug fixes

Elixir

• [File] Ensure File.cp_r/3 reports non-existing destination properly (instead of source)

ExUnit

• [ExUnit] Fix formatter crash when diffing takes too long
• [ExUnit] Ensure parallel matches in assert propagate type information

Logger

• [Logger] Fix regression where formatter would crash when given chardata (the crash would happen when logging non-ASCII characters)

Mix

• [mix help] Ensure app:APP works when the project or its dependencies were not yet compiled
• [mix escript.build] Ensure the hex application can be included in escripts

v1.19.3

Compare Source

1. Enhancements

Elixir

• [Kernel] Support /E modifier for regular expressions in config files

Mix

• [mix compile] Allow forcing specific compilers, such as --force-elixir, --force-app, etc
• [mix help app:APP] Support showing helps for apps in Elixir and Erlang standard libraries

2. Bug fixes

ExUnit

• [ExUnit.Case] Fix crash when formatting errors caused by a linked/trapped exit during setup_all

Mix

• [mix compile.app] Ensure functions in the format &Mod.fun/arity can be written to .app files
• [mix compile.app] Ensure strings with Unicode characters can be written to .app files

v1.19.2

Compare Source

1. Enhancements

Elixir

• [Kernel] Measure and optimize writing of .beam files in the compiler
• [Kernel] Optimize rare scenarios where type checking took too long

Mix

• [mix compile] Add flag --no-check-cwd to skip compiler check to aid debugging

2. Bug fixes

Elixir

• [IO] Fix dialyzer warning on IO.inspect :label
• [Kernel] Ensure we warn on deprecated ~~~ unary operator

Logger

• [Logger] Reset ansi escapes before newlines in Logger

Mix

• [mix compile] Warn if elixirc_paths is not a list of string paths

• [mix deps.compile] Improve reliability of MIX_OS_DEPS_COMPILE_PARTITION_COUNT across mix escript.install, mix archive.install, and others

v1.19.1

Compare Source

1. Bug fixes

EEx

• [EEx] Address Dialyzer warnings when invoking EEx.compile_string

Elixir

• [Kernel] Optimize how types are computed for pretty printing
• [Kernel] Optimize how differences are computed in the type system
• [Macro] Do not escape options given to dbg/2
• [Protocol] Improve protocol violation warnings

Mix

• [mix compile] Do not attempt to touch deleted files when compilation fails and then resumed with missing files
• [mix deps.compile] Do not spawn partitions when all dependencies are local and already compiled

v1.18.4

Compare Source

This release includes initial support for Erlang/OTP 28, for those who want to try it out. In such cases, you may use Elixir v1.18.4 precompiled for Erlang/OTP 27, as it is binary compatible with Erlang/OTP 28. Note, however, that Erlang/OTP 28 no longer allows regexes to be defined in the module body and interpolated into an attribute. If you do this:

@​some_attribute ~r/foo/
def some_fun, do: @​some_attribute

You must rewrite it to:

def some_fun, do: ~r/foo/
