  3. ## Language
  5. - [Stabilize `if let` guards on match arms](https://github.com/rust-lang/rust/pull/141295)
  6. - [`irrefutable_let_patterns` lint no longer lints on let chains](https://github.com/rust-lang/rust/pull/146832)
  7. - [Support importing path-segment keywords with renaming](https://github.com/rust-lang/rust/pull/146972)

  91. ## Rustdoc
  93. - [In search results, rank unstable items lower](https://github.com/rust-lang/rust/pull/149460)
  94. - [Add new "hide deprecated items" setting in rustdoc](https://github.com/rust-lang/rust/pull/151091)
  96. <a id="1.95-Compatibility-Notes"></a>
  98. ## Compatibility Notes
  100. - [Array coercions may now result in less inference constraints than before](https://github.com/rust-lang/rust/pull/140283)
  101. - Importing `$crate` without renaming, i.e. `use $crate::{self};`, is now no longer permitted due to stricter error checking for `self` imports.
  102. - [const-eval: be more consistent in the behavior of padding during typed copies.](https://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`.
  103. - [A future-incompatibility warning lint `ambiguous_glob_imported_traits` is now reported when using an ambiguously glob imported trait](https://github.com/rust-lang/rust/pull/149058)
  104. - [Check lifetime bounds of types mentioning only type parameters](https://github.com/rust-lang/rust/pull/149389)
  105. - [Report more visibility-related ambiguous import errors](https://github.com/rust-lang/rust/pull/149596)
  106. - [Deprecate `Eq::assert_receiver_is_total_eq` and emit future compatibility warnings on manual impls](https://github.com/rust-lang/rust/pull/149978)
  107. - [powerpc64: Use the ELF ABI version set in target spec instead of guessing](https://github.com/rust-lang/rust/pull/150468) (fixes the ELF ABI used by the OpenBSD target)
  108. - Matching on a `#[non_exhaustive]` enum [now reads the discriminant, even if the enum has only one variant](https://github.com/rust-lang/rust/pull/150681). This can cause closures to capture values that they previously wouldn't.
  109. - `mut ref` and `mut ref mut` patterns, part of the unstable [Match Ergonomics 2024 RFC](https://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.
  110. - [Add future-compatibility warning for derive helper attributes which conflict with built-in attributes](https://github.com/rust-lang/rust/pull/151152)
  111. - [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 [\#150151](https://github.com/rust-lang/rust/pull/150151), [\#151534](https://github.com/rust-lang/rust/pull/150151), and [rust-lang/cargo\#16557](https://github.com/rust-lang/cargo/pull/16557).
  112. - [The arguments of `#[feature]` attributes on invalid targets are now checked](https://github.com/rust-lang/rust/issues/153764)
  114. <a id="1.95-Internal-Changes"></a>
  116. ## Internal Changes
  118. These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools.
  120. - [Update to LLVM 22](https://github.com/rust-lang/rust/pull/150722)
