 ## 4.1.0 (2026-07-27)
 
 RBS 4.1 ships with JRuby support. The RBS parser is written in plain C without depending on the Ruby C API, so it is compiled to WebAssembly and runs on a Wasm runtime, with the parsed AST serialized in a binary format and decoded into RBS objects. The full test suite runs on JRuby in CI.
