Key user-facing enhancements include a faster window tiling method, support for Entra ID passkey login, and the ability to add PDF signatures. A significant under-the-hood change is the inclusion of "a full set of Rust-based core utilities," which aims to improve system security and performance by leveraging Rust's memory safety features.
