I've just released a new version with a re-written backend and FBInk integration. Notable changes include device rotation detection, faster page turns, a new screenshot feature, and simpler setup. More changes are listed in the notes on the
download page. The new version is larger - it'll take up ~5MB of the rootfs. This shouldn't be a problem, but I might look into running it off the onboard storage in the future.
Have tested it pretty thoroughly on my Sage and Glo, but would be grateful for any testing/feedback! Might be a couple of minor bugs where screenshots and logging will stop working after the server has been running for an extended period, but hopefully I managed to fix those. Shouldn't be anything that affects the core usability.
