It's Episode 300 — a milestone just under 6 years in the making! To celebrate, we kick things off with a fun song, then dive into the news: the Localize library v0.15.0 brings locale-aware formatting and Unicode CLDR data to Elixir without any compile-time code generation, a new library called Reach builds program dependence graphs for Elixir and Erlang to help coding agents and static analysis tools understand your codebase, Tidewave gets exciting updates including voice input with click-to-add context and the ability to install it as a PWA, the ErlEF has opened its 2026 board elections with voting running May 8-15, and more! Then we sit down with José Valim for an in-depth interview covering Elixir v1.20, the latest progress on the set-theoretic type system, the story behind Tidewave, and how AI is — and isn't — changing development on Elixir itself.
