Apache Druid
Druid 38 drops Java 17, recommends Java 25 and took longer to arrive than its predecessors
A side-by-side editorial comparison of Scalar and Tasmota — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Tasmota 16 adds optional MQTT 5.0 and DALI-2 commissioning for lighting control.
v16.0.0 Theo landed in mid-October. It adds optional MQTT 5.0 focused on request and response, initial ESP32-S31 and ESP32-C61 support, and DALI-2 device commissioning, input events and push-button bindings. HVAC work is also heavy, with a MiELHVAC web panel, Modbus RTU slave and Home Assistant discovery.

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.
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.

HVAC work is also heavy, with a MiELHVAC web panel, Modbus RTU slave and Home Assistant discovery.
The major number doesn't change the release's character: breadth remains the product. Two threads stand out from the driver list. Building-automation protocols are getting deeper support, with DALI-2, Modbus and OpenTherm's second heating circuit, and MQTT 5.0 updates the core messaging layer for the first time in these entries.
Expect the next release in about two months with further DALI-2 and Berry work, and fuller ESP32-S31 support, since the current support is labeled initial.
