v1.95.0

Compare Source

===========================

Language

• Stabilize if let guards on match arms
• irrefutable_let_patterns lint no longer lints on let chains
• Support importing path-segment keywords with renaming
• Stabilize inline assembly for PowerPC and PowerPC64
• const-eval: be more consistent in the behavior of padding during typed copies

• Make operational semantics of pattern matching independent of crate and module

Compiler

• Stabilize --remap-path-scope for controlling the scoping of how paths get remapped in the resulting binary

• ControlFlow::is_continue

Rustdoc

• In search results, rank unstable items lower
• Add new "hide deprecated items" setting in rustdoc

Compatibility Notes

• Array coercions may now result in less inference constraints than before
• 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.
  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
• Check lifetime bounds of types mentioning only type parameters
• Report more visibility-related ambiguous import errors
• Deprecate Eq::assert_receiver_is_total_eq and emit future compatibility warnings on manual impls
• powerpc64: Use the ELF ABI version set in target spec instead of guessing (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. 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, 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
• JSON target specs 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, #​151534, and rust-lang/cargo#16557.
• The arguments of #[feature] attributes on invalid targets are now checked

Internal Changes

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.

• Update to LLVM 22

v1.94.1

Compare Source

===========================

• Fix std::thread::spawn on wasm32-wasip1-threads
• Remove new methods added to std::os::windows::fs::OpenOptionsExt
  The new methods were unstable, but the trait itself is not sealed and so
  cannot be extended with non-default methods.
• Clippy: fix ICE in match_same_arms
• Cargo: update tar to 0.4.45
  This resolves CVE-2026-33055 and CVE-2026-33056. Users of crates.io are not affected.
  See blog for more details.

v1.94.0

Compare Source

==========================

Language

• Impls and impl items inherit dead_code lint level of the corresponding traits and trait items
• Stabilize additional 29 RISC-V target features including large portions of the RVA22U64 / RVA23U64 profiles
• Add warn-by-default unused_visibilities lint for visibility on const _ declarations
• Update to Unicode 17
• Avoid incorrect lifetime errors for closures

Platform Support

• Add riscv64im-unknown-none-elf as a tier 3 target

• <[T]>::array_windows
• <[T]>::element_offset
• LazyCell::get
• LazyCell::get_mut
• LazyCell::force_mut
• LazyLock::get

  (excluding those that depend directly on the unstable f16 type)
• f32::consts::EULER_GAMMA
• f64::consts::EULER_GAMMA
• f32::consts::GOLDEN_RATIO
• f64::consts::GOLDEN_RATIO

These previously stable APIs are now stable in const contexts:

• f32::mul_add
• f64::mul_add

Cargo

• Stabilize the config include key. The top-level include config key allows loading additional config files, enabling better organization, sharing, and management of Cargo configurations across projects and environments. docs #​16284
• Stabilize the pubtime field in registry index. This records when a crate version was published and enables time-based dependency resolution in the future. Note that crates.io will gradually backfill existing packages when a new version is published. Not all crates have pubtime yet. #​16369 #​16372
• Cargo now parses TOML v1.1 for manifests and configuration files. Note that using these features in Cargo.toml will raise your development MSRV, but the published manifest remains compatible with older parsers. #​16415
• Make CARGO_BIN_EXE_<crate> available at runtime

Compatibility Notes

• Forbid freely casting lifetime bounds of dyn-types
• Make closure capturing have consistent and correct behaviour around patterns
  Some finer details of how precise closure captures get affected by pattern matching have been changed. In some cases, this can cause a non-move closure that was previously capturing an entire variable by move, to now capture only part of that variable by move, and other parts by borrow. This can cause the borrow checker to complain where it previously didn't, or cause Drop to run at a different point in time.
• Standard library macros are now imported via prelude, not via injected #[macro_use]
  This will raise an error if macros of the same name are glob imported.
  For example if a crate defines their own matches macro and then glob imports that,
  it's now ambiguous whether the custom or standard library matches is meant and
  an explicit import of the name is required to resolve the ambiguity.
  One exception is core::panic and std::panic, if their import is ambiguous
  a new warning (ambiguous_panic_imports) is raised.
  This may raise a new warning (ambiguous_panic_imports) on #![no_std] code glob importing the std crate.
  Both core::panic! and std::panic! are then in scope and which is used is ambiguous.
• Don't strip shebang in expression-context include!(…)s
  This can cause previously working includes to no longer compile if they included files which started with a shebang.
• Ambiguous glob reexports are now also visible cross-crate
  This unifies behavior between local and cross-crate errors on these exports, which may introduce new ambiguity errors.
• Don't normalize where-clauses before checking well-formedness
• Introduce a future compatibility warning on codegen attributes on body-free trait methods
  These attributes currently have no effect in this position.
• On Windows std::time::SystemTime::checked_sub_duration will return None for times before the Windows epoch (1/1/1601)
• Lifetime identifiers such as 'a are now NFC normalized.
• Overhaul filename handling for cross-compiler consistency
  Any paths emitted by compiler now always respect the relative-ness of the paths and --remap-path-prefix given originally.
  One side-effect of this change is that paths emitted for local crates in Cargo (path dependencies and workspace members) are no longer absolute but relative when emitted as part of a diagnostic in a downstream crate.

Internal Changes

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.

• Switch to annotate-snippets for error emission
  This should preserve mostly the same outputs in rustc error messages.
