+## 19.4.0 (2024-11-27)
+
+This is a minor release with bug fixes and test improvements.
+
+### Features
+
+ - Add support for new OEMCrypto_GetBCCSignatureType() API. This API is optional
+   and only used on devices that support Provisioning 4 with a Phase 3 DICE
+   chain.
+   - Add credential types to client identification protobuf
+   - Return BCC signature type into client identification protobuf
+ - BCC extraction tool updates and refactoring
+   - Rewrite BCC, DeviceInfo and CSR Payload validators to cover info parsing,
+     validating and updating unit tests
+   - Update error codes returned by cbor/provisioning 4.0 validators to be less
+     severe when possible
+   - Add a few required fields for test-generated BCC
+ - Include licensing files with this release and future CE CDM releases
+
+### Tests
+
+ - Update license release tests to accomodate differences in behavior for CE
+   CDM and Android
+ - Update some CAST tests to enforce format of the message signed by
+   OEMCrypto_GenerateRSASignature()
+ - Add tool to extract BCC and build info for BCC uploading test
+ - Skip usage table tests on devices that don't support usage tables
+ - Fix key type used in InstallOemPrivateKeyCanBeUsed test
+ - Re-enable OEMCrypto security tests
+ - Allow multiple callbacks in TestSleep class to prevent multiple classes
+   trying to register a callback
+ - Improve error logging for tests
+   - Add log statement on failure when device with a TEST_ONLY system ID cannot
+     play production content
+
+### Bug Fixes
+
+ - Fix HLS parsing of bad content IDs
+ - Revert change to limit output buffer size during decrypt fallback due to
+   failures seen in 19.3 because the output buffer was not big enough
+ - Update blank OEMCrypto devsite test pages
+ - Small fixes to reduce compiler warnings
