This page contains firmware files for RUTM16 devices. Look to the table below or the changelog to find download links.

Stable firmware - this version has been tested through both internal QA processes and large-scale user deployments. All known issues have been resolved based on user reports and testing feedback. Stable firmware is currently used as the default for updates and is also deployed in mass production. To upgrade firmware using WebUI, follow the instructions in RUTM16 Firmware.
Latest firmware - this is the most recent firmware release, featuring the latest updates, features, and fixes. While it has passed internal testing, it has not yet undergone widespread deployment or user validation. It may still contain undiscovered issues. We recommend testing on a small number of devices before considering broader updates.

Note: packages for Package Manager are independent from firmware and can be downloaded in the Package Downloads page.
