fix RELEASES: we do not support upcasting to auto traits #119338 does not actually support casts from `dyn Trait` to `dyn Auto`, only from `dyn Trait` to `dyn Trait + Auto`. The following test does not compile ```rust trait Trait: Send {} impl<T: Send> Trait for T {} fn foo() { let x: &i32 = &1; let y = x as &dyn Trait as &dyn Send; } ``` it actually also doesn't compile with `feature(trait_upcasting)`, opened #126313 for that r? `@Mark-Simulacrum` `@cuviper` |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
