Support for vCenter/ESXi 7 Update 3

Does the latest version of vRanger 7.8.3 NOT support vCenter/ESXi 7 U3? vRanger hasn't had an update in over a year.  With the NUMEROUS security issues popping up with VMware where the remediation requires updating to the latest version, where does this leave us?  We can't update VMware beyond version 7 U2 if we want to continue using vRanger to back up.  So is it time to move on from vRanger which has been rock solid for over a decade?  This is very disappointing.
