 ==== Change to synthetic `_source` licensing
 
-Starting with this release, the <<synthetic-source,synthetic `_source`>> feature is available exclusively with the Enterprise subscription. Synthetic `_source` is used in logs data streams (`logsdb` index mode), time series data streams (TSDS, using `time_series` index mode), application performance monitoring (APM), and Universal Profiling.

-If you are using these capabilities and are not on an Enterprise license, the change will result in increased storage requirements for new data, as the synthetic `_source` setting will be ignored. Existing indices that used synthetic `_source` will remain seamlessly accessible.
