+## [1.3.1] - 2022-08-04
+
+### Added
+
+- Cdm and RemoteCdm can now be supplied a string value for `device_type` for scenarios where providing it as a string
+  is more convenient (e.g., from Config files).
+
+### Fixed
+
+- The `force_privacy_mode` key no longer needs to be defined at all in the configuration file. This was previously
+  crashing serve APIs if it wasn't set before starting.
+- RemoteCdm's Server version check will no longer fail under certain serving conditions e.g., Caddy prepending `Caddy`
+  to the Server header value. It also fixes case sensitivity and removed the full url from the header.
