Rust 1.97.0 Unveils Default Symbol Mangling and Improved Warning Handling

The Rust team has released Rust 1.97.0, introducing several key updates. The new version enables the Rust-specific symbol mangling scheme, v0, by default, replacing the legacy Itanium ABI-based mangling. This scheme ensures consistent and predictable symbol naming, particularly for generic parameters. Additionally, Cargo now supports configurable warning handling, allowing developers to silence, warn, or deny warnings during builds without invalidating the build cache. Linker output messages, previously hidden by default, are now visible to help diagnose potential issues. These updates aim to improve development efficiency and debugging clarity for Rust users.
