The first real update was released at the end of Feb 2023 – you can read about it here.
It seems that Amazon have quietly updated the eraser tool on their Kindle Scribe.
I believe that when I first received my Kindle Scribe, the erase tool was very basic, however when I used the device today, I noticed that there are now additional options to erase a selection (by drawing a ring around it) and to erase an entire page.
According to the device info, I am still running firmware version 5.16.1 (the same version as when it was shipped); however, I’m almost certain that these options were not previously available – if anyone can confirm or deny this, I’d be very grateful!
