REDIS-8.4.7 release notes and known issues

Summary

Update urgency: SECURITY : There are security fixes in the release. Security fixes #15673 Commands queued in a transaction could still access keys whose ACL permissions were revoked before the transaction was executed #15722 The cluster bus protocol has no authentication of its own unless tls-cluster is enabled, so any host able to reach a node's bus port could join the cluster and threaten it. A cluster node now warns at startup when its bus port is left unauthenticated, and the new cluster-bus-port-protected-mode option (default no ) makes refusing to run in that state an explicit choice: set it to yes and the node starts only when tls-cluster authenticates the bus TimeSeries: Prevented Redis from crashing when adding samples to a compressed Time Series key restored from a malformed RDB payload Vector Sets: Deeply nested JSON used in Vector Set queries could cause the server to crash
