The weekly digest landed overnight with kache 0.3.0 featured in tooling updates, while the crates ecosystem continues its steady expansion with new robotics and audio schema packages.

This Week in Rust Issue 652 published [1], delivering the community's curated roundup of the past seven days across language, tooling, and project updates. The digest now features kache 0.3.0 in its Project/Tooling Updates section [2], highlighting continued momentum in the ecosystem's supporting infrastructure. Across crates.io-index, five new and updated packages landed: weaveffi-gen-wasm and weaveffi-gen-node both pushed new versions [3] [4], while moosicbox_schema updated its audio processing components [5]. The registry also saw the inaugural publication of use-robotics [6], signaling fresh interest in Rust's robotics story. Behind the scenes, documentation links got tightened up with 301 redirect resolution [7], and the all-hands meeting documentation refreshed its README [8], keeping internal coordination tools current.
