+### Added
+
+- Added `py.typed` file to support PEP561 and silence Mypy.
+
+### Changed
+
+- Dropped support for Python 3.7.
+- Recompiled protobuffers for version 4.25.
+
+### Fixed
+
+- Missing `yaml` dependency as it was only installed alongside the `serve` extras group.
+- Duplicate Concatenated SignedMessages no longer throw a verification failure in `Cdm.set_service_certificate()`.
+  To ensure security of the messages, verification will still fail if any of the SignedMessages do not match each other.
