@ -324,6 +324,12 @@ The following deprecated APIs are removed.
* Support arm64 / aarch64 on UNIX platforms.
* Building YJIT requires Rust 1.58.1+. [[Feature #18481]]
* Physical memory for JIT code is lazily allocated. Unlike Ruby 3.1,
the RSS of a Ruby process is minimized because virtual memory pages
allocated by `--yjit-exec-mem-size` will not be mapped to physical
memory pages until actually utilized by JIT code.
* Introduce Code GC that frees all code pages when the memory consumption
by JIT code reaches `--yjit-exec-mem-size`.
