The final episode of Thinking Elixir after six incredible years of weekly episodes! We send things off in style with a packed news segment covering Phoenix LiveView 1.2's new colocated CSS powered by the @scope at-rule, the retirement of the long-standing Earmark Markdown library and why you should migrate to MDEx, a major Sagents v0.8.0 release bringing durable interrupts, and structured extraction, PostgreSQL 19's exciting new features including graph queries, SpaceX's jaw-dropping $60 billion acquisition of Cursor, and more! Finally, David shares his new role on the Erlang Ecosystem Foundation board, and Mark talks about what's next for Sagents and his exciting new AI-native startup. Thank you for six wonderful years. We're so glad you were here along the way and now for the final episode!

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. HexDocs is rolling out per-package subdomains for improved browser security isolation, the Erlang Ecosystem Foundation has launched an Ecosystem Registry to help answer "who uses this?" for Erlang, Elixir, and Gleam companies, and the Lua library for Elixir is approaching its v1.0 release with a brand new pure-Elixir Lua 5.3 VM. On the security front, a sophisticated self-replicating worm called Miasma compromised 73 Microsoft GitHub repos by exploiting legitimate OIDC tokens and valid SLSA provenance, even weaponizing AI coding tools like Claude Code and Cursor, raising fresh questions about supply chain safety and whether Hex might benefit from a cooldown mechanism like the one Ruby just shipped, and more!

Security takes center stage this week as the EEF's Jonatan Mรคnnchen 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 issues, including outright bugs, that 1.19 completely missed. Dannote releases "vibe", an ambitious BEAM-native coding agent for Elixir/OTP projects featuring a TUI, LiveView web console, subagents, and more!
