Elixir shipped a breaking change that blocks a dangerous metaprogramming pattern, and you need to know what code it flags.

The core team disallowed unquote inside quoted patterns [1], closing a footgun that confused developers and broke silently [2]. This is the kind of safe-by-default change that prevents bugs before they hit production. Alongside that, Elixir fixed dependency compilation logic to only skip cleaning for path dependencies, letting fetch dependencies run through their normal workflow [3]. Meanwhile, Phoenix LiveView added a version check that warns when your tailwind dependency is too old for ColocatedCSS to work properly [4], catching integration issues at dev time instead of deplore time. The ecosystem also rolled routine dependency updates for GitHub Actions and CodeQL analysis tooling [5] [6].

Action items

→ Audit quoted patterns in your codebase for unquote calls and refactor them before upgrading elixir-lang/elixir [plan]
→ If using Phoenix LiveView with ColocatedCSS, ensure tailwind is 0.5+ phoenixframework/phoenix_live_view [plan]
→ Test dependency recompilation workflows after upgrading to verify env cleaning works as expected elixir-lang/elixir [monitor]
