Elixir v1.19.3 has been released with several enhancements and bug fixes. Enhancements include support for the /E modifier for regular expressions in config files, the ability to force specific compilers in mix compile (e.g., --force-elixir, --force-app), and support for showing help for apps in Elixir and Erlang standard libraries via mix help. Bug fixes address a crash in ExUnit.Case when formatting errors caused by a linked/trapped exit during setup_all, and a fix in mix compile.app to ensure functions in &Mod.fun/arity format can be written to .app files.
