Key enhancements include raising an error when regexes are used as default values in struct fields (for Erlang/OTP 28 compatibility) and adding key-based partitioning of duplicate registries. Bug fixes address type checking not completing on protocol consolidation, ExUnit crashing on empty test unit groups, and Mix issues with `mix help app:APP` and module preloading in `mix test --slowest-modules=N`. José Valim notes this RC is fully compatible with Erlang/OTP 28.1+, adapts struct update syntax into a type assertion operator, and resolves slow compilation issues. ## Full article daily.dev links to this article rather than hosting it.
