The Rust Security Response Team was notified that Miri stores all environment variables to target/, allowing secrets to persist in caches. While not necessary a vulnerability in and of itself, when paired with GitHub Actions caching behavior, it is possible for this to expose…
We believe that there is an ongoing campaign targeting rust-lang members and owners of popular crates that is attempting to compromise devices and accounts in order to use them to publish malware. What we've seen A video call is set up for something positive — maybe for a job…
After nearly 4 years of active development, the next-generation trait solver is close to stabilization. We are enabling it by default on nightly to surface any remaining issues and plan to stabilize it in the next months. This is the largest single change to the Rust compiler…
Rust BlogWith Rust 1.100.0, the following changes to 32-bit Windows targets will happen: i686-pc-windows-msvc Tier 1 with host tools target will be demoted to Tier 1 without host tools. i686-pc-windows-gnu Tier 2 with host tools target will be demoted to Tier 2 without host tools. Builds…
Language - Add allow-by-default raw_borrows_via_references lint that checks for references that decay immediately into raw borrows - Extend unconditional_panic lint to function calls that panic when the chunks/windows size is zero - Stabilize C-variadic function definitions…
The Rust team is happy to announce a new version of Rust, 1.99.0. Rust is a programming language empowering everyone to build reliable and efficient software. If you have a previous version of Rust installed via rustup, you can get 1.99.0 with: $ rustup update stable If you don't…
At the end of August, we announced our first Maintainers in Residence, Rust Project contributors who are funded for their upstream contributions and maintenance work from the Rust Foundation Maintainers Fund (RFMF). Since then, the Rust Leadership Council has dedicated more funds…
One of the biggest challenges Rust developers report in our annual surveys is a subpar debugging experience. So, back in February, we ran our first Rust Debugging Survey, in the hopes of identifying how Rust developers are using debuggers and what problems they are facing when…
- rustc: fix miscompilation in generating vtables
The Rust team has published a new point release of Rust, 1.98.1. Rust is a programming language that is empowering everyone to build reliable and efficient software. If you have a previous version of Rust installed via rustup, getting Rust 1.98.1 is as easy as: rustup update…
The rustup team is happy to announce the release of rustup version 1.29.1. Rustup is the recommended tool to install Rust, a programming language that empowers everyone to build reliable and efficient software. What's new in rustup 1.29.1 The headlines of this release are…
We are very happy to announce the Rust Project's first round of Maintainers in Residence: Gen Li (@rami3l), Chris Denton (@ChrisDenton), Alejandra González (@blyxyas), León Liehr (@fmease), and Maintainer Grant recipients: Jason Newcomb (@Jarcho) and Jonas Böttiger (@joboet).…
Language - Allow shortening lifetime of &mut when unsize-coercing, even in an invariant position. For example, you can now coerce a Cell to a Cell . Such shortenings were already previously allowed when coercing a &mut to a &, or coercing a & to a &. - Add deny-by-default…
- rustc: Fix miscompilation in LLVM optimization This backports an LLVM submodule bump to include the LLVM-side fix and a revert of the rustc change that is one known trigger for the bug. The rustc side revert should not be strictly necessary but is done out of abundance of…
Language - Consider Result and ControlFlow to be equivalent to T for must use lint - Add allow-by-default dead_code_pub_in_binary lint for unused pub items in binary crates - Stabilize the div32, lam-bh, lamcas, ld-seq-sa and scq target features - Stabilize…
- Cargo: fix timeout/retry behavior - Cargo: apply patches for CVE-2025-15661, CVE-2026-55199, and CVE-2026-55200 to libssh2 - rustc: fix miscompilation in MIR optimization
Language - Allow passing expr metavariable to cfg - Always coerce never types in tuple expressions - Avoid incorrect inference guidance of function arguments in rare cases - Support s390x vector registers in inline assembly - Allow using constants of type ManuallyDrop as patterns…
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…
- 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…
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…
