rustup 1.29.1 adds parallel updates and component installs, deprecates implicit toolchain installation

Rust Blog 3 weeks ago 2 min read ↗ Original

rustup 1.29.1 improves concurrency for updates and component additions, deprecates implicit toolchain installation, and adds a local HTTP server for documentation.

WHY IT MATTERS

Updating Rust toolchains and adding multiple components will be faster due to parallel execution. The deprecation of implicit toolchain installation means scripts relying on this behavior will now emit warnings and need updating eventually.

The three things worth knowing

`rustup update` and `rustup component add` now perform checks and installations in parallel.

Implicit installation of the active toolchain is deprecated and will produce a warning.

`rustup doc` supports a `--serve` flag to serve documentation over local HTTP for containerized setups.
