Upstream ships one hard-coded firmware source, and its two catalogues disagree by a whole release. Here the source is a setting, and every candidate arrives with its checksum.

Firmware sources, opened from the Firmware page: this fork, the SD card and upstream's two catalogues.

The argument

Versions are compared numerically, so 2.10 is not older than 2.9 -- which a string comparison says and which upstream's own updater believes. A source that publishes no checksum is labelled TLS only rather than treated as verified, because trusting a transport is not the same as verifying bytes.
