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). These contributors will...

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 since its initial relea...

What happened On 2026-08-20 at 7:15 UTC we got a report that the proc-macro1 crate was malicious. The Rust Security Response Team verified this to be the case: the crate had a build script that was downloading a malicious payload. This crate proc-macro1 and others like it (proc-macro-en, aovine, aro...

The Rust team is happy to announce a new version of Rust, 1.98.0. 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 1.98.0 with: $ rustup update stable If you don't have it already, yo...

TL;DR We are enabling the next iteration of the borrow checker (coined Polonius Alpha) on nightly in preparation for stabilization in the next few months. Whaaaaaat? Yes! You heard it right! The next iteration of the Rust borrow checker is coming! Rust's first borrow checker ("AST borrowck") was ver...

The Rust team has published a new point release of Rust, 1.97.1. 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 1.97.1 is as easy as: rustup update stable If you don't have...

Another six months have passed since our last development update, and the crates.io team has been busy. Here's a summary of the most notable changes and improvements made to crates.io since then. Source Code Viewer Crate pages now have a "Code" tab that lets you browse the contents of published crat...

This is another post in our series covering what we learned through the Vision Doc process. We previously described the overall approach and what we learned about doing user research, we explored what people love about Rust, dug into what it takes to ship safety-crticial Rust, and described some of ...

If you want to financially support the development of Rust, please consider donating to the Rust Foundation Maintainers Fund. A few months ago, the Rust Foundation announced the Rust Foundation Maintainers Fund (RFMF). Since then, the Rust Project has been closely cooperating with the Rust Foundatio...

The Rust Security Response Team was notified that Cargo incorrectly handled symlinks inside of crate tarballs downloaded from third-party registries, allowing a malicious crate to override the source code of another crate from the same registry. This vulnerability is tracked as CVE-2026-5223. The se...

The Rust Security Response Team was notified that Cargo incorrectly normalized the URLs of third-party registries using the sparse index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within the same domain, an attacker able to publish crates in a regis...

The 2025H2 Project Goal period has now concluded. Over these months, the Rust Project pursued 41 Project Goals, 13 of which were designated as Flagship Goals. This post contains curated updates on our progress since the last post and the final status for each of the goals (many of which continue as ...

The Rust Project has been building up a good history of participating in various open-source mentorship programs, including Google Summer of Code for three years (including this year) and previously OSPP. We're happy to announce that this year we are also participating in Outreachy starting in the M...

The nvptx64-nvidia-cuda target is a compilation target for NVIDIA GPUs. When using this target, the final output is PTX. Two version choices shape that output: a GPU architecture (for example, sm_70, sm_80, …), which determines which GPUs can run the PTX, and a PTX ISA version, which determines whic...

As previously announced, the Rust Project is participating in Google Summer of Code (GSoC) 2026. GSoC is a global program organized by Google that is designed to bring new contributors to the world of open source. A few months ago, we published a list of GSoC project ideas, and started discussing th...

The Rust team is happy to announce a new version of Rust, 1.95.0. 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 1.95.0 with: $ rustup update stable If you don't have it already, yo...

Building fewer targets by default On 2026-05-01, docs.rs will make a breaking change to its build behavior. Today, if a crate does not define a targets list in its docs.rs metadata, docs.rs builds documentation for a default list of five targets. Starting on 2026-05-01, docs.rs will instead build do...

Rust's WebAssembly targets are soon going to experience a change which has a risk of breaking existing projects, and this post is intended to notify users of this upcoming change, explain what it is, and how to handle it. Specifically, all WebAssembly targets in Rust have been linked using the --all...

The Rust team has published a new point release of Rust, 1.94.1. 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 1.94.1 is as easy as: rustup update stable If you don't have...

The Rust Security Response Team was notified of a vulnerability in the third-party crate tar, used by Cargo to extract packages during a build. The vulnerability, tracked as CVE-2026-33056, allows a malicious crate to change the permissions on arbitrary directories on the filesystem when Cargo extra...

When we set out to understand Rust's challenges, we expected to hear about the borrow checker learning curve and maybe some ecosystem gaps. Of course, we did. A lot. But, of course, it's more nuanced. The conventional wisdom is that Rust has a steep learning curve, but once you "get it," smooth sail...

We would welcome people to try and report issues with the nightly-only cargo -Zbuild-dir-new-layout. While the layout of the build dir is internal-only, many projects need to rely on the unspecified details due to missing features within Cargo. While we've performed a crater run, that won't cover ev...

The rustup team is happy to announce the release of rustup version 1.29.0.
