New Firmware Update for Kindle Oasis Adds Hardened DRM

Amazon has released firmware update 5.18.2.1.1 for the Kindle Oasis 3, which appears to introduce hardened DRM protections. The update lacks new user-facing features, and Amazon's release notes are notably vague about what was changed.

Background

The Kindle Oasis 3 (10th gen, 2019) is Amazon's flagship e-reader. Amazon has a history of tightening DRM through firmware updates to protect content partnerships with publishers and rights holders.
