Updates on Elixir V1.12
summary
Elixir 1.12 adds concrete, usable features: mix install enables per-script dependency installation (cached in the OS temp dir), system:trap_signal lets scripts handle signals, and tight OTP 24 integration brings JIT with ~30–40% faster compilation in practice, binary float-16 support, and EEP-54 extended argument errors. Language changes include stepped ranges (explicit // step allowing empty ranges), new kernel macros tap/then, IEx autocompletion improvements, HEEx template parsing for LiveView, and Livebook tooling — all shipped and working in the release.
