This Week in Rails

This week's Rails changelog covers security releases for versions 7.2.3.2, 8.0.5.1, and 8.1.3.1 addressing an Active Storage RCE vulnerability. Performance improvements include faster i18n initialization (400ms → 250ms) and optimized template resolution. Thread-safety fixes land for lazy route loading, thread_mattr in Ractors, and controller middleware stacks. Several deprecations are introduced for TransactionState predicates, positional #insert arguments, and the binds argument to to_sql. Additional changes include token authentication scheme support, improved SQL logging with positional markers, and Arel-based RETURNING handling.

Faster i18n loading, thread-safe routes, and more!
