With the release of PEx v10.4 update 1, the release notes say in Section H:
Vybrid limitations:.....Derivatives with security features (MVFxxNSxxx) are not included. They are supported by a
separate service pack
The release notes for PEx have had this since the 10.3 release.
Is the service pack for the Vybrid security features (e.g. CAAM) available yet? How can I get it?
