It is not expected to affect any existing published    crates. Can be fixed by refactoring the involved types or opting    into the `sized_hierarchy` unstable feature. See the [FCP report]    (rust-lang/rust#137944 (comment))    for a code example.- The warn-by-default `elided_named_lifetimes` lint is [superseded  by the warn-by-default `mismatched_lifetime_syntaxes` lint.]  (rust-lang/rust#138677)- [Error on recursive opaque types earlier in the type checker]  (rust-lang/rust#139419)- [Type inference side effects from requiring element types of  array repeat expressions are `Copy` are now only available at the  end of type checking]  (rust-lang/rust#139635)- [The deprecated accidentally-stable  `std::intrinsics::{copy,copy_nonoverlapping,write_bytes}` are now  proper intrinsics]  (rust-lang/rust#139916). There are no  debug assertions guarding against UB, and they cannot be coerced  to function pointers.- [Remove long-deprecated `std::intrinsics::drop_in_place`]  (rust-lang/rust#140151)- [Make well-formedness predicates no longer coinductive]  (rust-lang/rust#140208)- [Remove hack when checking impl method compatibility]  (rust-lang/rust#140557)- [Remove unnecessary type inference due to built-in trait object impls]  (rust-lang/rust#141352)- [Lint against "stdcall", "fastcall", and "cdecl" on non-x86-32 targets]  (rust-lang/rust#141435)- [Future incompatibility warnings relating to the never type (`!`)  are now reported in dependencies]  (rust-lang/rust#141937)- [Ensure `std::ptr::copy_*` intrinsics also perform the static  self-init checks]  (rust-lang/rust#142575)Internal Changes----------------These changes do not affect any public interfaces of Rust, but they representsignificant improvements to the performance or internals of rustc and relatedtools.- [Correctly un-remap compiler sources paths with the `rustc-dev` component]  (rust-lang/rust#142377)
