Issue 670’s most notable bits: sysknife has contributor tasks for fixing rollback status reporting, preserving other servers when uninstalling its MCP configuration, and handling unsalted hashes of unredacted request parameters. The Rust project merged 618 PRs, including Polonius performance work, Dir::try_clone, const iteration for ranges, and stabilization of trim_prefix/trim_suffix and CommandExt::show_window. No Rust/Cargo/Rustup calls for testing this week; crate of the week is fastlogging-rs.
