Runtime Briefing — Ruby 3.3 Release

Executive briefing: The Ruby core team released Ruby 3.3.0 on 25 December 2023, improving interpreter performance and tooling foundations.

Highlights

• Prism parser preview. New parser architecture improves tooling accuracy and paves the way for future Ruby syntax evolution.
• YJIT gains. Incremental JIT enhancements reduce warmup penalties and expand platform support.
• RJIT experiment. A new research JIT built in Ruby explores maintainable optimisation paths.

Adoption guidance

• Test key applications (Rails, Sidekiq, Shopify-style workloads) under Ruby 3.3 to measure YJIT changes and memory usage.
• Update buildpacks, container images, and Heroku/Paas manifests to deliver Ruby 3.3 and capture new dependency requirements.
• Coordinate with static analysis and formatting tool maintainers as they transition to the Prism parser pipeline.
