The day combined a visible extension capability with protocol and marketplace changes. App-server consumers should pay particular attention to the renamed thread-items method.

Alpha release context: 5 official tags were published that UTC day (rust-v0.143.0-alpha.11, rust-v0.143.0-alpha.12, rust-v0.143.0-alpha.13, rust-v0.143.0-alpha.14, rust-v0.143.0-alpha.15). The full comparison contains 65 commits and at least 300 changed files.
