Heads up, I noticed the latest firmware (I downloaded it today but it appears to be from august) added Dark Mode! Nice.
My reader is a frankenvivlio (maybe that's why it didn't find the update by itself).
Version number is 6.8.2102. All in all, quite a lot of changes but nothing else that I'd personally notice.
