+## [Version 19.1][v19.1]
+
+This is a minor release that includes a few security fixes and bug fixes.
+
+General
+
+- Change OEMCrypto_FreeSecureBuffer() |output_descriptor| parameter to be
+[in,out] type.
+- Use strlen() instead of sizeof() to get the length of BUILD_INFO.
+- Add OEMCrypto_GetEmbeddedDrmCertificate() definition to OPK, with
+OEMCrypto_ERROR_NOT_IMPLEMENTED.
+- Remove default.h include file from wtpi_config, which was causing a mismatch
+between reported config values and actual config values.
+- Remove extra is_debug field and trailing comma from BuildInformation.
+- Reduce trusted clock skew on restarts in wtpi_reference implementation.
+- Remove -Wno-unused-parameter cflag.
+- Increase transport buffer size from 32K to 34K to accommodate larger buffer
+requirements from OEMCrypto_LoadProvisioning
+- Fix BCC payload item count in wtpi_reference
+- Add WTPI_DeriveNewAsymmetricKeyHandle() and
+WTPI_CreateUDSDerivedAsymmetricKeyHandle() to wtpi_provisioning_4_interface.h.
+These implementations are only required if you are using
+wtpi_reference/wtpi_provisioning_4.c.
+
+OPK serialization layer
+
+- Avoid writing any value to output parameters if the OEMCryptoResult is not
+OEMCrypto_SUCCESS. (Applies to [out] type only. Not [in] or [in,out]). This
+avoids subtle bugs where the serialization logic may unexpectedly modify (eg
+set to 0) an output parameter on failure.
+- Initialize pointers in a few corner cases.
+
+Tests
+
+- Fix default cipher mode for CAS unit test.
+- Skip entitlement session tests that are only supported on CAS devices.
+- Don't force decrypt count to increase in unit tests.
+- Skip some cast tests if not supported.
+
+OP-TEE port changes
+
+- Fix memory leaks on failure cases in AES decrypt, RSA key creation, and ECC
+key creation.
+- Check incoming message size from REE to avoid OOB.
+- Generate ECC keypair and zero pad appropriately.
+- Add file existence check in RPMB impl.
+- Cleanup keybox and key handles consistently after use.
