 ### 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
+ - Updated `HasRootOfTrustBeenRenewed()` to detect Drm Reprovisioning
+ - Updated CE BCC extraction tool:
+   - Added a Makefile to `wv_factory_extractor` tool
+   - Added an option to run BCC validator with the tool
+ - Refactored `ProvisioningHolder` to separate generate, fetch, and load
+   operations
 
 ### 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
+ - Ignored certain errors during `RemoveOfflineLicense()` for apps which have
+   been unprovisioned
+ - Allowed `key_session` to be equal to `oec_session` when removing entitled
+   key sessions
+
+### Tests
+
+ - Added test `PrintClientAndServerVersionNumber` that prints the core message
+   info for both provisioning and license request/response
+ - Updated provisioning server version test to accommodate v16 responses
+ - Relaxed BCC validation test requirements, downgrading non-critical errors
+   to warnings and improving output clarity
+ - Added integration test to verify that renewal is not needed before renewal
+   delay seconds
+ - Added check to verify that renewals include client ID when "always includes
+   client ID" is true
+ - Updated `CdmUseCase_LicenseWithRenewal` test to verify that request has
+   correct info for persistent license
+ - Added a test to verify PST with length 127 succeeds
+ - Added new duration tests:
+   - A test for loading licenses unrelated to the content being played back
+   - Tests for the `30sSoftRental_UnlimitedPlayback` scenario
+   - Tests with past and future license start time policies
+   - Tests for short playback timers with unlimited rental duration
+
+### Dependency Updates

+ - Updated BoringSSL to latest (e4b6d4f7)
