Seven patch releases — versions 7.2.17, 7.4.12, 8.2.11, 8.4.8, 8.6.8, 8.8.4 and 8.10.3 — all fix the same high-risk issue: a heap buffer overflow when propagating a publish or sharded publish message larger than four gigabytes over the cluster bus. Oversized messages in…

Second, data model expansion. Pull request 15938 adds per-member expiration to sets, mirroring hash field expiration. New commands include Sadd Ex, expire and persist variants, and time-to-live queries, with lazy and active expiration, new persistence types, and full replication support. For operators, that means…
