Redis 8: vector sets, AGPL returns, Stack in core

Redis 8 folds Search/JSON/TimeSeries/Bloom into core under AGPL, adds Vector Sets for AI workloads, and deprecates the standalone Stack distribution.

Redis 8.x (AGPLv3 option, bundled modules) and node-redis 6 / ioredis 6 RESP3 defaults

Redis 8

As of: 2026-06

What's in 8.x

  • Vector Sets (beta in 8.0, stabilised later) — native ANN similarity search for AI/RAG workloads without a separate vector DB.
  • AGPLv3 returns alongside RSALv2/SSPL — self-hosters regain OSI "open source" status.
  • Search/JSON/TimeSeries/Bloom ship in core — no separate Stack distribution.
  • New commands: EXPIRETIME precision, CLIENT KILL MAXAGE, improved INFO sections.
  • Multi-threaded core improvements; query-latency gains in Search.

Upgrade notes

  • 8.0 deprecates standalone Redis Stack — migrate module configs to core equivalents.
  • 8.8 (mid-2026) added async replication improvements — read the changelog if you run replicas.
  • JSON/Search active by default changes maxmemory planning on small boxes.
