# Elixir v1.19 released: enhanced type checking, broader type inference, and up to 4x faster compilation for large projects

## Summary

Elixir v1.19 introduces significant improvements to its type system with enhanced type inference across all constructs, type checking for protocols and anonymous functions, and better error detection at compile time. The release delivers up to 4x faster compilation for large projects through lazy module loading and parallel dependency compilation. It adds official support for Erlang/OTP 28, includes OpenChain compliance with Source SBoM attestation, and brings various quality-of-life improvements including better documentation access via Mix commands.
