OpenESL v0.9.1 (retracted)

A patch release for the tags. Tag firmware 0.9.0 could draw a grey, half-finished image with the old one showing through, while it told the AP the image was shown; 0.9.1 waits awake through the display refresh again, as 0.8.2 did (#283). Every tag on 0.9.0 should get it. The AP and the C6 radios have not changed.

Upgrading from 0.9.0 to 0.9.1

Order: only the tags. Every tag on 0.9.0 firmware should get the tag image of 0.9.1, one of each model first as usual (section 3). Nothing the AP or either C6 radio does has changed, so neither needs an update: their images say 0.9.1 only because the AP builds some of the tag's source files too (tools/fw_version.py), and the file that changed (tag/src/epd.c) is not one of them. Updating the AP anyway does no harm. Nothing is one-way: a tag on 0.9.1 talks to the AP as a 0.9.0 tag does, keeps its settings, radio key and channel, and takes older firmware as before.

All details, and what going back costs: docs/release.md. From an older release: upgrading over more than one release.
