Rust 1.96.0 introduces copyable range types that allow developers to store slice accessors more easily and adds new assertion macros that provide detailed output on failures, improving debugging efficiency. The update also enhances WebAssembly linking by rejecting undefined symbols outright, which helps catch configuration errors early in the build process. Additionally, two security patches address vulnerabilities related to third-party package registries, though users of crates.io are unaffected. Overall, this release resolves long-standing ergonomic issues and strengthens the language's safety and usability features
Rust 1.96.0 released
Rust 1.96.0 finally delivers copyable range types that let developers store slice accessors without fighting the compiler or splitting start and end values. The release also adds assert_matches macros that actually print failing values, which saves hours of debugging compared to wrapping everything in standard assertion calls. WebAssembly builds just got stricter since the linker now rejects undefined symbols outright instead of quietly converting them into env imports. Two registry security patches fix symlink extraction and URL normalization flaws, though crates.io users can safely ignore those particular warnings.
