Redis

Three breaking changes: default read/write timeouts and retry backoff changed to cross-SDK-standard values, WaitAOF now returns *IntSliceCmd, and PubSub.Receive hang on short subscribe confirmations is fixed. Adds Redis 8.10 support with HIMPORT, LMOVEM/BLMOVEM, new time-series and search commands, plus a systematic data-race and parser-hardening sweep.

Async Redis clients now support server-pushed maintenance notifications, matching the sync client. New commands include LMOVEM/BLMOVEM for lists, SDIFFCARD/SUNIONCARD for sets, MAXCOUNT/MAXSIZE for XREAD/XREADGROUP, and multiple Timeseries and Search additions. Bug fixes address Sentinel pool capacity loss, RESP3 hiredis connection detection, and geo lat/lon swap.

New time-series commands (TS.NRANGE, TS.NREVRANGE, TS.READ, TS.QUERYLABELS, EXCLUDEEMPTY, multi-aggregator), RediSearch additions (FT.ALIASLIST, COLLECT reducer, HNSW RERANK, timeout warnings, stemmer languages), and core client commands (SUNIONCARD, SDIFFCARD, LMOVEM, BLMOVEM, ZREVRANK WITHSCORE, COMMAND DOCS, XREAD MAXCOUNT/MAXSIZE). A large batch of fixes ensures zero-valued optional arguments (LIMIT 0, DB 0, SAMPLES 0, etc.) are no longer dropped from the wire, plus cluster and sentinel connection-lifecycle fixes. The HIMPORT command family is experimental.

Compact hashes store field names once per schema, reducing memory for keys sharing a schema. Adds HIMPORT for high-throughput bulk insertion, BACKUP for node-side backup/restore, TLS peer certificate authentication, list move commands (LMOVEM, BLMOVEM), and cardinality commands (SUNIONCARD, SDIFFCARD). Stream fixes include a blocked-listener bug after SORT…STORE and a defragmentation division-by-zero fix.

Full support for the new Array data type in Redis 8.8 — create, browse, search, aggregate, and edit elements from Redis Insight. Also a What's New popup, IPv4/IPv6 connection choice, and editing host and port for existing connections.

Commands can now automatically prefix keys via a new keyPrefix option, and cluster clients can call getNodeClientForKey to target WATCH/MULTI/EXEC transactions to a specific node.

Redis 8.6 is now available on Redis Cloud Pro.

Internal fixes and improvements.

Improved proxy efficiency and fixed a bug where node join failures occurred due to misidentified IPv6 addresses. Also fixed -MOVED response metrics visibility.

Internal fixes and improvements.

Fixed several bugs including incomplete cleanup of stale Redis processes, LDAP certificate-based authentication blocking local user authentication, high CPU from excessive heartbeat logging, and -MOVED response metrics visibility. Also addressed internode encryption certificate issues.
