Redis

Shipped Redis 8.10 GA with compact hashes, then landed a wave of client SDK releases adding hybrid caching, auto-pipelining, and cluster-aware routing.

Redis 8.10 went GA with compact hashes, multi-element list moves, and server-to-server TLS. Compact hashes store field names once per shared schema, reducing memory. New commands include HIMPORT for bulk compact hash insertion, LMOVEM/BLMOVEM for moving multiple list elements, SUNIONCARD/SDIFFCARD for set cardinality without materializing sets, and BACKUP for MP-AOF node-based backup and restore. XREAD/XREADGROUP gained MAXCOUNT and MAXSIZE reply caps. TLS peer certificate-based server-to-server authentication was added.

Security fixes shipped across all maintained branches (6.2–8.8) for RESTORE-based use-after-free and out-of-bounds writes. Crafted stream RESTORE payloads could cause use-after-free leading to remote code execution; RedisBloom and TDigest RESTORE payloads could trigger out-of-bounds writes. Fixed in 8.8.1, 8.6.5, 8.4.5, 8.2.8, 7.4.10, 7.2.15, and 6.2.23.

go-redis 9.22.0 shipped experimental client-side caching and automatic pipelining. The caching layer keeps hot keys local to the client; auto-pipelining groups queued commands. Default timeouts, retry backoff, and cluster-state reload intervals now align with a cross-SDK configuration proposal, and WaitAOF returns *IntSliceCmd — a one-line fix for callers.

node-redis 6.2.0 made cluster commands follow the server's routing policy. Multi-key commands like MGET, MSET, and DEL split across hash slots automatically, so cross-slot calls that previously failed with CROSSSLOT now work. Fan-out commands run across every shard with aggregated replies, SCAN walks the whole cluster, and replica read-scaling aligns with server flags.

redis-py 8.1.0 added async maintenance notifications and new command coverage. The asyncio client now handles server-pushed maintenance events for standalone and cluster setups, and added LMOVEM, BLMOVEM, SDIFFCARD, SUNIONCARD, and stream MAXCOUNT/MAXSIZE options.

RedisInsight 3.8.0 added full Array data-type support — create contiguous or sparse Arrays, edit elements inline or multiline, and run aggregations. A "What's New" popup highlights top features after upgrades with per-version browsing.
