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. ## Full article daily.dev links to this article rather than hosting it.
