AI Summary

This release focuses on optimizing knowledge indexing and file search performance, along with database tuning and CI improvements. Key updates include stopping probe operations when probes saturate and recovering vector candidates discarded by HNSW post-filtering.

Key Highlights

  • Optimized knowledge indexing by stopping probe operations once overview probes saturate.
  • Recovered vector candidates that were being discarded by HNSW post-filtering.
  • Tuned document autovacuum to handle connector sync churn more efficiently.
  • Increased memory for file-search indexing workers.
  • Restricted CLI telemetry token usage to build and publish steps.

New Features

  • Stop consuming access batches once overview probes saturate
  • Stop re-probing known indexing providers per access batch
  • Store connector sync schedules at millisecond precision
