Rust version 1.91.0 has been officially released, showcasing enhancements in reliability and efficiency in programming. A notable highlight is the promotion of the aarch64-pc-windows-msvc target to Tier 1 support, which guarantees the highest level of support for users on 64-bit ARM systems operating Windows. Furthermore, a new warn-by-default lint has been introduced to prevent issues related to dangling raw pointers from local variables being returned by functions. This aims to enhance safety when dealing with raw pointers and unsafe code practices.
In this release, several APIs have also been stabilized, making them available for use in all contexts, including const contexts. Among the new features are:
- Path::file_prefix: This method returns the file name without its directory path.
- Stabilized methods for atomic pointers, including operations like `fetch_ptr_add` and `fetch_or`.
- New methods for integers, such as `strict_add` and `strict_sub`.
- Methods for panicking hooks and new methods for handling paths, path buffers, and durations.
- Implementations of PartialEq for types like PathBuf and str, as well as methods for managing IPv4 and IPv6 addresses.
- Default implementations for pinned types including `Pin>`, `Pin>`, and `Pin>`.
Additionally, some previously stable APIs are now accessible in const contexts, including `OsString::new`, `PathBuf::new`, and others.
For developers looking to install or update to Rust 1.91.0, the process is straightforward via rustup. Users can simply run `rustup update stable` to upgrade if already on a prior version, or download rustup from the official website if not yet installed. Those wishing to assist in testing future releases can opt for the beta (`rustup default beta`) or nightly (`rustup default nightly`) channels and report any bugs discovered during the testing phase.
The aarch64-pc-windows-msvc target’s Tier 1 promotion ensures that the Rust compiler will execute its full test suite on this platform with each change, while the aarch64-pc-windows-gnullvm and x86_64-pc-windows-gnullvm targets have been elevated to Tier 2 support, albeit with some host tools still pending release.
