summary
Announces concrete Rails and Ruby changes: Rails will enable YJIT in production by default and ships an initializer to enable JIT after boot, reporting about a 15% performance improvement; a new option forces active_record.connection to raise so code migrates to a block form with_connection to reduce DB connections; Shopify teams release prism parser and a pure Ruby protuff implementation that beats C parsers by ~9x; Ruby 3.3 adds faster object-shape caches (functional red‑black trees) and Ruby 3.4 adds a register allocator.
