ELIXIR FIXES BINARY COMPREHENSION REGRESSION, ACCESS MODULE GAINS KEYWORD SUPPORT

Elixir shipped fixes for a critical binary comprehension bug that broke pattern matching with options, while expanding the Access module to handle keyword lists alongside maps.

The binary comprehension regression [1] addressed a broken optimization that caused incorrect results when using the `uniq: true` option with pinned variables and operations in bitstring patterns. This fix [2] restores consistency across static sizes, pinned variable sizes, and operations, ensuring `for` loops with bin patterns behave predictably across all input scenarios. Separately, `Access.key/2` and `Access.key!/1` now support keyword lists [3] [4], expanding the module's utility beyond maps and bringing API consistency across different data structure types. Phoenix tightened ColocatedCSS requirements [5], now explicitly requiring tailwind >= 0.5 to prevent new apps from shipping in an unsupported state. The framework also refactored CI to isolate installer tests [6] [7], decoupling the installer's Elixir version matrix from Phoenix's library support matrix, fixing duplicate test runs during CI. A small but important win: `Kernel.put_elem/3` missed an optimization pass [8] that's now corrected for better performance on tuple updates.

Action items

→ Pull the binary comprehension fix immediately if you use bitstring patterns with options elixir-lang/elixir [immediate]
→ Update Phoenix to 1.8.8+ if using ColocatedCSS; verify tailwind >= 0.5 in your deps phoenixframework/phoenix [plan]
→ Monitor CI pipeline if you maintain custom installer tooling; Phoenix's test matrix split may affect your builds phoenixframework/phoenix [monitor]
