+- `moq-dev-rs` client: `builds/moq-dev-rs/Cargo.lock` resolves `moq-tokio`
+  0.19.28 and `moq-net` 0.3.15, whose tagged `rs/moq-net/src/version.rs`
+  defines `ALPN_20`. The client parses `MOQ_CLIENT_VERSION` with
+  `moq_net::Version`'s `FromStr`, so no client code changes.
+- `moq-dev-js` client: the published `@moq/net` 0.4.7 tarball offers
+  `Ietf.ALPN.DRAFT_20` in `connection/connect.js`.
+- Relay: the adapter wraps `docker.io/moqdev/moq-relay:latest`, the same
+  digest as `0.17.10`, built from `moq-relay-v0.17.10`.
+
+This README's remaining work: open a PR on `englishm/moq-interop-runner`
+that adds `draft-20` to the `moq-dev-rs` and `moq-dev-js` entries in
+`implementations.json`, rewrites both notes (they call 18 and 22 the only
+versions main retains), and fixes the two moq-dev rows in its `README.md`
+table, which still say drafts 14-17. No pin bump is needed. The maintainer
 approved posting there on 2026-10-24.
