Here are some possible changes in the 5.16.21 firmware. As usual some of these features might not be fully implemented yet or may require remote enabling by Amazon.
- Mention of a new Kindle device "11th generation, 2024 Release" along with new Mediatek device drivers.
- Add the ability to encrypt the Kindle file system: "Your device content is not encrypted. Please update to the latest software version and factory reset your device. If you need further assistance, please contact customer service at www.amazon.com/devicesupport.", "Kindle encrypts the following data on this device to keep it secure:", "Your Kindle is encrypted", "To fully secure your device, we recommend setting a device PIN."
- Inclusion of code related to handwritten annotations in non-Scribe firmware. Might just be to simplify the code base.
- More work toward a new method of storing annotations on the device.
- Possible annotation types: highlight, outline, underline.
- Two column layout for the AA menu.
