-### 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.
