What is changing with docs.rs targets in 2026?

Only one default target built unless you specify more in Cargo.toml. Affects new releases and rebuilds.

How do I add multiple targets to docs.rs?

In Cargo.toml: [package.metadata.docs.rs] targets = ["x86_64-unknown-linux-gnu", "x86_64-apple-darwin"] — list exactly what you need.

Will docs.rs still support all Rust targets?

Yes, any from the toolchain. Just not by default.
