Rust 1.91.0 introduces aarch64-pc-windows-msvc as a Tier 1 platform, enhancing support for 64-bit ARM systems on Windows. The update also adds a lint for dangling raw pointers and stabilizes several APIs for use in const contexts.

Programming in dynamically typed languages can lead to uncertainty about library stability, but Clojure's ecosystem is noted for its strong reputation for stability. Factors contributing to this stability include the language's design principles, such as immutability, the use of namespaces over monkey-patching, and a community culture that prioritizes non-breaking changes in library updates.
