Can it break my build?

The release lists these compatibility notes. Most only affect rare code, but read them before you raise your toolchain in CI:

Use it

rustup update stable        # get the newest release
rustup install 1.10          # or exactly this one
rustup override set 1.10     # pin a project to it

To require at least this version from users of your crate, set rust-version = "1.10" under [package] in Cargo.toml. Cargo then refuses to build it on older compilers with a clear message, and with resolver 3 (the default on the 2024 edition, Rust 1.85+) it also prefers dependency versions that support it.
