What is Node-RED?

Node-RED 5.0.9 lets users drag-order flows in the explorer and adds error badges to tabs.

Node-RED maintains two lines. 5.0.9 is a larger-than-usual maintenance release: flows can be drag-ordered in the Explorer sidebar, tabs and the explorer show error badges, HTML script and style blocks get JavaScript and CSS support, Monaco moves to 0.57, and CSV, Range, RBE, Filter and MQTT nodes get fixes. 4.1.17 backports only the merge-conflict resolution fixes.

What is Scalar?

Scalar is testing demand for hosting from inside localhost

The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.

Node-RED 5.0.9 lets users drag-order flows in the explorer and adds error badges to tabs.

◆ Current state

Node-RED maintains two lines. 5.0.9 is a larger-than-usual maintenance release: flows can be drag-ordered in the Explorer sidebar, tabs and the explorer show error badges, HTML script and style blocks get JavaScript and CSS support, Monaco moves to 0.57, and CSV, Range, RBE, Filter and MQTT nodes get fixes. 4.1.17 backports only the merge-conflict resolution fixes.

◆ Where it's heading

The 5.x line is now taking editor usability work from a wider set of contributors, with six first-time contributors in 5.0.9. The 4.1.x branch stays on backports only. The feed shows no 5.1 or new major feature yet.

◆ Prediction

Expect more 5.0.x releases with editor improvements; the entries don't show when a 5.1 with larger features will arrive.

Scalar is testing demand for hosting from inside localhost

◆ Current state

The October 1.76 run put a sticky developer toolbar above the API reference on localhost, with Configure, Share, Deploy and Generate SDK tools in a side panel. The Deploy tool now shows a waitlist for API hosting on Scalar, and 1.76.4 records the server framework with each sign-up. AsyncAPI rendering kept improving, with binding schemas shown as structured properties. In another package line, 0.20.0 moved to Undici 8 with HTTP/2 on by default and raised the minimum Node.js version to 22.19.0.

◆ Where it's heading

The reference is becoming a dev-time workbench, not only a published page. Tools that sat in dropdowns moved to a persistent panel, and SDK generation was consolidated there. The hosting waitlist is the commercial signal: Scalar is collecting framework data from developers at the moment they run their API locally, which gives it a demand measure before committing to a deployment flow. AsyncAPI work remains the other steady investment.

◆ Prediction

Expect the waitlist to turn into a hosting beta, with the first supported frameworks chosen from the data 1.76.4 collects; FastAPI, Hono and Express are already named for detection. The monorepo's patch cadence should otherwise continue daily or near it.
