What shipped

Why it matters

This week focused on performance improvements across the standard library, particularly in Calendar operations and the Inspect module which see heavy use in everyday Elixir development. Several fixes address type system accuracy and error reporting, while memory optimization work reduces garbage collection pressure.

Post for LinkedIn

This week's updates to Elixir improve performance across Calendar operations (datetime, date, and time shifting are now 1.2-2x faster) and the Inspect module, reduce memory allocations in formatting, fix type system accuracy for list subtraction, and correct error reporting for function arity mismatches. Changes target commonly-used standard library functions that benefit development and production workloads.
