rclnodejs v2.1.1 (2026-07-22)

Adds Server-Sent Events (SSE) subscribe support to the rclnodejs/web HTTP transport (#1537), so browsers and other HTTP clients can stream live ROS 2 topic data over plain HTTP — no WebSocket, no SDK. Enable it with sse: true (or --http-sse on the CLI); cors is also now supported (--http-cors <origin>).

const es = new EventSource('http://localhost:9001/capability/subscribe/scan');
es.addEventListener('message', (e) => console.log(JSON.parse(e.data)));

Also in this release: node-gyp pinned to ^12.2.0 (13.x dropped Node 20 support, breaking the arm64 CI leg), c8 bumped to ^12.0.0 (#1560), and the JSDoc site now rebuilds from git tags instead of gh-pages branch state (#1553).
