Weaviate v1.37.3: cluster steadiness and async replication improvements
Action Required
Upgrading to v1.37.3 will improve cluster stability and async replication reliability for Weaviate deployments using hnsw or MMR indexes, reducing downtime during rebalances and node failures.
AI Impact Summary
Weaviate v1.37.3 delivers stability improvements for cluster coordination and asynchronous replication. It addresses flaky RAFT-related tests and snapshot/restore workflows, hardens startup paths for compactv2 migrations, and optimizes hashtree comparisons for multi-node scenarios, plus a new async replication scheduler. These changes reduce downtime during rebalances and node outages and improve operational reliability across index types like hnsw and MMR. The ChangeType.DEPRECATION tag suggests some older paths may be sunset in future releases, so plan validation and migration tests accordingly.
