Changes

This is the first major release of node-redis since 5.x. The headline change is RESP3 by default, alongside broader Redis 8.8 command coverage, pubsub/cluster reliability fixes, and a bumped minimum Node.js version.

Key changes

• RESP3 is the default protocol — opt back into RESP2 explicitly if you need the old wire format
• Node.js 20 is the new minimum supported runtime
• Redis 8.8 coverage — new array commands, INCREX / INCREXBYFLOAT, ZINTER/ZUNION COUNT aggregator, XNACK, CLIENT UNBLOCK
• Sentinel & cluster pubsub fixes for failover-moved connections and sharded topology recovery
• Stack modules exposed on pool type and the core client classes are now publicly re-exported
