+## 19.1.0 (2024-03-28)
+
+Note: Release v19.0 was skipped so that this release's version number matches
+the OEMCrypto version.
+
+CE CDM v19.1.0 includes all changes from CE CDM v18.5.0.
+
+## Features
+
+  - Supports up to OEMCrypto v19.1, including new OEMCrypto tests introduced
+    since OEMCrypto v18.
+  - Added support for License Protocol v2.2, which uses SHA256-signed license
+    requests.
+  - Raised the minimum required version of C++ to C++17.
+  - Added a new error code, `kDeviceRevoked`, which requires special handling.
+    - `kDeviceRevoked` may be returned from any method that processes a service
+      response. It indicates that the device's root of trust has been revoked
+      and is no longer trusted.
+    - All service interactions will fail after this, even after a device reboot
+      or factory reset. Apps may want to handle this error by using a different
+      DRM system, if supported.
+    - Devices that support renewal can escape this condition by renewing their
+      root of trust. Root of trust renewal is outside the scope of CE CDM.
+      You'll need to work directly with your Widevine contact.
+  - Improved code performance slightly by reducing copy operations.
+  - Added additional tests to check for problems when moving usage entries.
+
+## Bug Fixes
+
+  - Fixed a potential out-of-bounds read in the logging code for certain
+    invalid severity level values.
+  - Fixed many minor issues identified via static analysis.
