Elixir v1.20 has officially landed, marking a huge milestone as the language is now officially a gradually typed language, type checking every single line of code without requiring developer annotations, and even prompting some developers to drop Dialyzer entirely.

306: Don't Exhaust Your Atoms
Security takes center stage this week as the EEF's Jonatan Männchen highlights that atom exhaustion accounts for roughly one tenth of all CVEs in the BEAM ecosystem and Sobelow can help catch it before it hits production. Hackney users get an urgent nudge to upgrade to v4.0.3, which patches 9 CVEs including high-severity issues and fixes missing HTTP/3 certificate verification, thanks in part to Peter Ullrich's AI-assisted vulnerability research. On the exciting side, the new Elixir 1.20-rc.6 type system is proving its worth in the real world, with Tyler Young reporting it caught ~500…
