My Boox Page just received this firmware update today. It was on version 3.5 before. I don’t see any release notes on their website yet, but here’s a summary of what’s showing on my device:

System/Apps:

1. Support for importing system fonts
2. Support for customizing the navigation bar
3. Fixed input method covering input boxes in some apps
4. Support for using email or phone number to unbind other Onyx accounts

Library/Neoreader:

1. Fixed the issue of being unable to long-press to select words
2. Support for sharing directly after opening a document
3. Support for bulk OCR for PDF docs (Onyx account login required)

The update is 1.5GB.
