CONNECT-RUST 0.4.0 SHIPS WITH BUFFA 0.5.0 SYNC AND COMPANION FILES

Connect-rust v0.4.0 lands major codegen overhaul with file-per-package layout and companion file support, syncing the entire Protobuf stack for cleaner builds.

The connect-rust team shipped v0.4.0 [1] with three critical codegen improvements that reshape how Rust services are generated. The release bumps buffa to 0.5.0 [2], adopting companion file emission (`<stem>.__connect.rs`) [2] and the new `file_per_package` output layout [3] that collapses per-proto splits into a single dotted-package file with all service stubs inlined—a direct win for BSR cargo SDK generation and tonic-style integrations. Graceful shutdown now matches Go's net/http.Server.Shutdown behavior [1], fixing a long-standing async cleanup gap. Python SDK parity is closing fast: `include_hook_events` [5] now surfaces PreToolUse, PostToolUse, and Stop events as HookEventMessage, the Python agent SDK added xhigh effort support [6] to match Opus 4.7's capability ceiling, and defer-round-trip support [4] brings the Python SDK into sync with TypeScript for permissioned tool execution. The cwc-makers plugin shipped zero-install onboarding [7] for Cardputer flashing events, with a curl+tar fallback [8] that kills the git dependency entirely on every OS. Claude Code and Agent SDK both bumped to 2.1.129 and 0.2.129 [9] across the action suite.
