95.3 fixes a memory leak in our in-memory compute implementation, reported by our customers. By default, Kpow runs its compute using Kafka Streams, which is unaffected.

Symptoms of the memory leak include degraded UI performance and deployment restarts after 24+ hours of uptime. This issue has been observed in larger Kpow installations with many clusters, tenants, and resources configured.

Upgrade to 95.3 if you:

  • Use Kpow with PERSISTENCE_MODE=audit or PERSISTENCE_MODE=none
  • Are a Flex enterprise customer
  • Use Kpow Community or Flex Community
