8.5.1 release notes

Upgrading to Enterprise Search 8.5.1? See Upgrading and migrating.

Fixes a bug where a missing Github README could crash a Workplace Search Github content source sync job.

Elastic Cloud downscales Enterprise Search nodes on deployments that don’t use Enterprise Search. Due to a bug, this also occurs for deployments that do not use App Search engines or Workplace Search content sources.
- You may run into this issue if you only use the Elastic web crawler, native connectors, or existing indices, without creating a corresponding App Search engine.
- The workaround is to re-enable Enterprise Search from the Edit page of your Elastic Cloud deployment. Then, create a corresponding App Search engine for the index, or search-* index, to avoid hitting the bug again.
Deployments do not collect Enterprise Search logs when using Docker images. See known issues for logs and logging for details.
Deployments do not collect Enterprise Search logs when using Enterprise Search service account tokens. See known issues for logs and logging for details and workaround.
