Rollup merge of #126314 - lcnr:fix-relnotes, r=pietroalbini
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`
