Some rustdoc news:

* When you use search and filter on `import`, it will now also include reexported extern (PR: github.com/rust-lang/ru...)

In rustdoc search, when using `macro` filter, it will now include attribute and derive macros as well.

PR: github.com/rust-lang/ru...

[rustdoc] Include attribute and derive macros when filtering on "macros" by GuillaumeGomez · Pull Request #148176 · rust-lang/rust

As discussed here, some filters should have been "grouped". This PR allows attribute and derive macros to match the macro filter. I'll wait for #148005 to add more tests as it would r...

After next docs.rs server update, you will be able to use `additional-targets` in your Cargo.toml docs.rs metadata. That will allow you to not have to re-declare the whole default list target but instead to just add more platforms as you see fit

Should simplify things :)

I'm excited to share what I've been working on with @erikjee.bsky.social: RustNL's #rustlang Maintainers Fund!

Many people and companies contributing to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that.

We are setting out to employ 6 full-time maintainers and 6 interns in 2026 to make sure #rustlang is well maintained and bugs and contributions get the attention they need.

The Rust GCC backend is now tested as part of the Rust merge CI process. \o/

We should now hopefully spend a lot less time on syncs and focus on increase the support for the GCC backend.

Love the logic! That also explains why I'm never able to understand the syntax whenever I stop reading/writing Makefiles for a few days.

Well, yes. I like to have text copyable and I just need to connect printer USB to my computer. So very low effort. :)

Just published the `0.37.2` version of the Rust sysinfo crate.

It improves some docs, fixes `System::uptime` on Android and improved how modified/removed processes exe paths are handled.
