Closing Keynote
summary
Announcements hit specific work and numbers: Rails will enable wet by default in production and teams report about 15% performance improvement on real apps, with an initializer to toggle JIT after boot; Active Record gains an option to make connection caching raise so code migrates to with_connection blocks; Ruby 3.3 ships the prism parser and object‑shape cache improvements, Ruby 3.4 plans a register allocator, and pure‑Ruby parsers (protuff, GraphQL) outpace C implementations by large factors.
