TL;DR
- Amazon has begun rolling out software update 5.19.3 to supported Kindles.
- USB-transferred PDFs now support highlights, notes, and improved navigation.
- Kindle Scribe adds direct writing on sideloaded PDFs
Amazon is rolling out a new software update to its Kindle devices, though as always, users should temper expectations. These updates are typically incremental, and while 5.19.3 introduces some new PDF-centered improvements, it also comes with its own risks of breaking features or introducing changes you’d rather roll back.
