Release notes of Opera extension 1.39.3

Where are release notes of Opera extension 1.39.3? I could not find these even in GitHub nor in https://addons.opera.com/en-gb/extensions/details/bitwarden-free-password-manager/

If the release does not contain a file “dist-opera-2131.zip” but only files named “Source code”, is the change log still related to Opera version?
