For information about the Kibana 8.15.0 release, review the following information.

The 8.15.0 release includes the following known issues.

Known issues

edit
Kibana fails to start when processing YAML configuration keys that contain dotted notation in objects in arrays

Details
In 8.15.1, We fixed a bug when processing YAML configuration keys that contain dotted notation in objects in arrays. This can manifest as a validation error causing Kibana to not start.

For more information, refer to #190590.

Connectors require update due to Microsoft Teams product retirement

Details
The original method for configuring incoming webhooks in Microsoft Teams is being retired. Refer to Retirement of Office 365 connectors within Microsoft Teams and #187823.

Impact
If you used the Incoming Webhook app in Microsoft Teams to generate a webhook URL for a Microsoft Teams connector, it will stop working in December 2024.

Workaround
Use the Workflows app in Microsoft Teams to create a new webhook URL, as described in Configure Microsoft Teams. Update your Microsoft Teams connector to use the new URL before the end of December 2024.

Incorrect index errors related to inference endpoints

Details
In 8.15.1, we fixed a UI bug where an index error about the semantic_text field would be incorrectly displayed when the inference endpoint was configured and available.

You can ignore this error if you’ve confirmed that the inference endpoint is configured and the model is deployed.

This bug is fixed in #189283.

Deprecations

edit

The following functionality is deprecated in 8.15.0, and will be removed in 9.0.0. Deprecated functionality does not have an immediate impact on your application, but we strongly recommend you make the necessary updates after you upgrade to 8.15.0.

Uptime is deprecated in 8.15.0 and will be removed in a future version.

Details
The Uptime app is already hidden from Kibana when there is no recent Heartbeat data, and will be completely removed in early 2026. You should migrate to Synthetics as an alternative. For more details, refer to the Uptime documentation.

Search sessions are deprecated in 8.15.0 and will be removed in a future version.

Details
Search sessions are now deprecated and will be removed in a future version. By default, queries that take longer than 10 minutes (the default for the advanced setting search:timeout) will be canceled. To allow queries to run longer, consider increasing search:timeout or setting it to 0 which will allow queries to continue running as long as a user is waiting on-screen for results.

Breaking changes

edit

Breaking changes can prevent your application from optimal operation and performance. Before you upgrade to 8.15.0, review the breaking changes, then mitigate the impact to your application.

Adds rate limiting to install by upload endpoint.

Details
Rate limiting was added to the upload api/fleet/epm/packages endpoint. For more information, refer to #184036.

Impact
If you do two or more requests in less than 10 seconds, the subsequent requests fail with 429 Too Many Requests. Wait 10 seconds before uploading again. This change could potentially break automations for users that rely on frequent package uploads.
