<a id="1.95-Compatibility-Notes"></a>

## Compatibility Notes

- [Array coercions may now result in less inference constraints than
before](https://redirect.github.com/rust-lang/rust/pull/140283)
- Importing `$crate` without renaming, i.e. `use $crate::{self};`, is
now no longer permitted due to stricter error checking for `self`
imports.
- [const-eval: be more consistent in the behavior of padding during
typed copies.](https://redirect.github.com/rust-lang/rust/pull/148967)
In very rare cases, this may cause compilation errors due to bytes from
parts of a pointer ending up in the padding bytes of a `const` or
`static`.
- [A future-incompatibility warning lint
`ambiguous_glob_imported_traits` is now reported when using an
ambiguously glob imported
trait](https://redirect.github.com/rust-lang/rust/pull/149058)
- [Check lifetime bounds of types mentioning only type
parameters](https://redirect.github.com/rust-lang/rust/pull/149389)
- [Report more visibility-related ambiguous import
errors](https://redirect.github.com/rust-lang/rust/pull/149596)
- [Deprecate `Eq::assert_receiver_is_total_eq` and emit future
compatibility warnings on manual
impls](https://redirect.github.com/rust-lang/rust/pull/149978)
- [powerpc64: Use the ELF ABI version set in target spec instead of
guessing](https://redirect.github.com/rust-lang/rust/pull/150468) (fixes
the ELF ABI used by the OpenBSD target)
- Matching on a `#[non_exhaustive]` enum [now reads the discriminant,
even if the enum has only one
variant](https://redirect.github.com/rust-lang/rust/pull/150681). This
can cause closures to capture values that they previously wouldn't.
- `mut ref` and `mut ref mut` patterns, part of the unstable [Match
Ergonomics 2024
RFC](https://redirect.github.com/rust-lang/rust/issues/123076), were
accidentally allowed on stable within struct pattern field shorthand.
These patterns are now correctly feature-gated as unstable in this
position.
- [Add future-compatibility warning for derive helper attributes which
conflict with built-in
attributes](https://redirect.github.com/rust-lang/rust/pull/151152)
- [JSON target
specs](https://doc.rust-lang.org/rustc/targets/custom.html) have been
destabilized and now require `-Z unstable-options` to use. Previously,
they could not be used without the standard library, which has no stable
build mechanism. In preparation for the `build-std` project adding that
support, JSON target specs are being proactively gated to ensure they
remain unstable even if `build-std` is stabilized. Cargo now includes
the `-Z json-target-spec` CLI flag to automatically pass `-Z
unstable-options` to the compiler when needed. See
[#&#8203;150151](https://redirect.github.com/rust-lang/rust/pull/150151),
[#&#8203;151534](https://redirect.github.com/rust-lang/rust/pull/150151),
and
[rust-lang/cargo#16557](https://redirect.github.com/rust-lang/cargo/pull/16557).

checked](https://redirect.github.com/rust-lang/rust/issues/153764)
