It's Tuesday, October 6th, 2026, and this is Frigate NVR Updates.
The headline is reliability at scale: a fix for MQTT disconnects on busy systems, alongside a cleanup of tracking code and smaller interface improvements.
First, connection stability. PR 24573 resolves a reconnect loop reported in issue 24010. On a 16-camera system, the main process exceeded 2,100 open descriptors. The broker accepted each connection, but the MQTT client loop returned error 7 because the underlying select call cannot handle file descriptors above…
Second, a simpler, cheaper tracking pipeline. PR 24559, landed as commit 9ab52c2, simplifies the ONVIF controller and auto tracker. The controller no longer keeps a separate copy of camera configuration, cached service requests are replaced with plain requests at the call site, and the separate tracker thread class…
Finally, usability. PR 24543, landed as commit dab0d85, adds an overflow menu to system tabs on mobile. Open PR 24570 covers improved Reolink detection in the camera setup wizard, while PR 24567 collects limited-detail fixes on the 0.18 branch around media handling and the camera info dialog.
What's next: verify the MQTT fix under high descriptor…
