* Raised the minimum required CMake version to 3.17 to fix Linux builds with libcurl v8.21.0 when linking static library dependencies.
* Metadata preclass scans now run before the final scan verdict.
* ClamOnAcc: Fixed errors when recursively excluded paths are children of an included path.
* ClamOnAcc: Fixed hash bucket list corruption when two watched paths collide in the same bucket.
Tenable has extracted the preceding description block directly from the SUSE security advisory.
