Ruby 3.4

Ruby 3.4 is an easy-to-use, interpreted, dynamically-typed, and object-oriented programming language designed for productivity. This version introduces Prism as the default parser, enhancing performance, error tolerance, and long-term maintainability. It also features the new “it” block parameter for cleaner block references and Happy Eyeballs v2 for faster connection resolution. Additionally, the JSON parser is optimized to be up to 1.5x faster, while YJIT memory usage tracking is significantly improved.
