OpenESL v0.8.2

Upgrading from 0.8.1 to 0.8.2

Order: the AP, then, only with an S3 and a C6 on a cable, the C6 if you want to update it over the cable from now on. The tag firmware has not changed (the tag image of this release is 0.6.0), and neither has the C6 over WiFi (netradio). Nothing the AP stores changes: an AP that goes back to 0.8.1 keeps its data, its layout files and its name.

The S3 with a C6 on a cable can update its C6 radio over the cable (#240): the release has openesl-ap-radio-esp32c6-<version>-ota.bin (and -lcd-), sent like AP firmware with esl-client ota ... --wait or from the dashboard, which shows the radio under Firmware. This needs the radio on 0.8.2 once, over USB: a C6 flashed before 0.8.2 has one app slot and link v1 (radio.ota false in GET /api/ota). It keeps working with a 0.8.2 S3, so this flash can wait. The Flash AP tab erases the radio's flash anyway; pick the -lcd image for a radio with the screen. One-way for the radio only (#240: a new partition table and link v2): going back to an older radio image means the Flash AP tab, since older releases have no radio -ota.bin. Host and radio of link v1 and v2 work together in both directions. The S3 + plain C6 on a cable is supported now (tried on hardware on 2026-10-26); the C6 with screen as the radio is still experimental.

seen_s_ago in GET /api/tags and /api/health no longer shows a huge number (an unsigned wrap of about 2^64 ms) when a tag polls while the AP builds the reply (#244). The same wrap could flag such a tag silent and show it as long gone in the dashboard. Clients that turned it into a date (Prisjakt did) got a year far in the past.

From an older release: upgrading over more than one release. Every detail: docs/release.md.
