rust-lang/rust (rust-lang/rust)

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

Refer to Rust's platform support page
for more information on Rust's tiered platform support.

Libraries

• Relax T: Ord bound for some BinaryHeap<T> methods.

Stabilized APIs

• <[T]>::array_windows
• <[T]>::element_offset
• LazyCell::get
• LazyCell::get_mut
• LazyCell::force_mut
• LazyLock::get
• LazyLock::get_mut
• LazyLock::force_mut
• impl TryFrom<char> for usize
• std::iter::Peekable::next_if_map
• std::iter::Peekable::next_if_map_mut
• x86 avx512fp16 intrinsics
  (excluding those that depend directly on the unstable f16 type)
• AArch64 NEON fp16 intrinsics
  (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.

v1.93.1

Compare Source

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

• Don't try to recover keyword as non-keyword identifier, fixing an ICE that especially affected rustfmt.
• Fix clippy::panicking_unwrap false-positive on field access with implicit deref.
• Revert "Update wasm-related dependencies in CI", fixing file descriptor leaks on the wasm32-wasip2 target.

v1.93.0

Compare Source

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

Language

• Stabilize several s390x vector-related target features and the is_s390x_feature_detected! macro
• Stabilize declaration of C-style variadic functions for the system ABI
• Emit error when using some keyword as a cfg predicate
• Stabilize asm_cfg
• During const-evaluation, support copying pointers byte-by-byte
• LUB coercions now correctly handle function item types, and functions with differing safeties
• Allow const items that contain mutable references to static (which is very unsafe, but not always UB)
• Add warn-by-default const_item_interior_mutations lint to warn against calls which mutate interior mutable const items
• Add warn-by-default function_casts_as_integer lint

Compiler

• Stabilize -Cjump-tables=bool. The flag was previously called -Zno-jump-tables.

Platform Support

• Promote riscv64a23-unknown-linux-gnu to Tier 2 (without host tools)

Refer to Rust's platform support page
for more information on Rust's tiered platform support.

Libraries

• Stop internally using specialization on the Copy trait as it is unsound in the presence of lifetime dependent Copy implementations. This may result in some performance regressions as some standard library APIs may now call Clone::clone instead of performing bitwise copies
• Allow the global allocator to use thread-local storage and std::thread::current()
• Make BTree::append not update existing keys when appending an entry which already exists
• Don't require T: RefUnwindSafe for vec::IntoIter<T>: UnwindSafe

Stabilized APIs

• <[MaybeUninit<T>]>::assume_init_drop
• <[MaybeUninit<T>]>::assume_init_ref
• <[MaybeUninit<T>]>::assume_init_mut
• <[MaybeUninit<T>]>::write_copy_of_slice
• <[MaybeUninit<T>]>::write_clone_of_slice
• String::into_raw_parts
• Vec::into_raw_parts
• <iN>::unchecked_neg
• <iN>::unchecked_shl
• <iN>::unchecked_shr
• <uN>::unchecked_shl
• <uN>::unchecked_shr
• <[T]>::as_array
• <[T]>::as_mut_array
• <*const [T]>::as_array
• <*mut [T]>::as_mut_array
• VecDeque::pop_front_if
• VecDeque::pop_back_if
• Duration::from_nanos_u128
• char::MAX_LEN_UTF8
• char::MAX_LEN_UTF16
• std::fmt::from_fn
• std::fmt::FromFn

Cargo

• Enable CARGO_CFG_DEBUG_ASSERTIONS in build scripts based on profile
• In cargo tree, support long forms for --format variables
• Add --workspace to cargo clean

Rustdoc

• Remove #![doc(document_private_items)]
• Include attribute and derive macros in search filters for "macros"
• Include extern crates in search filters for import
• Validate usage of crate-level doc attributes. This means if any of html_favicon_url, html_logo_url, html_playground_url, issue_tracker_base_url, or html_no_source either has a missing value, an unexpected value, or a value of the wrong type, rustdoc will emit the deny-by-default lint rustdoc::invalid_doc_attributes.

Compatibility Notes

• Introduce pin_v2 into the builtin attributes namespace
• Update bundled musl to 1.2.5
• On Emscripten, the unwinding ABI used when compiling with panic=unwind was changed from the JS exception handling ABI to the wasm exception handling ABI. If linking C/C++ object files with Rust objects, -fwasm-exceptions must be passed to the linker now.
