+[[lens-7.5]]
+=== Lens&mdash;a new way to create visualizations (beta)
+
+Lens is a simple, more intuitive way to visualize your data. Lens provides a 
+drag-and-drop experience that helps you get from your data to insights 
+in just a few clicks. If there is a better visualization for your data, 
+Lens makes smart visualization suggestions for you, which allows you to 
+quickly switch between visualization types. Want to use a different data set? 
+With Lens, you can simply choose a different index pattern right from the UI. 
+//Check out our documentation for full details.

+[[smart-query-cancellation-7.5]]
+=== Smart query cancellation
+
+Starting in 7.5, if you navigate to a different page or 
+update a query before getting the results, {kib} applies a smart cancellation policy,
+canceling the 
+{es} query.  Canceling unnecessary queries improves cluster performance 
+by reducing noise caused by queries that you no longer need.

+[[canvas-shareables-7.5]]
+=== Canvas workpads outside of Kibana
+
+Canvas introduces shareables, a new way to externally share information from 
+{kib}.  Shareables enables our community to share static Canvas workpads 
+using a code snippet. When the workpad is added to your website, 
+you can customize the workpad behavior to autoplay the pages.

+[[maps-7.5]]
+=== More Maps enhancements
+
+GeoJSON upload was released as Beta in 7.3, 
+and now it's production ready in 7.5.   
+GeoJSON upload makes it easier to add custom vector shapes to your map. 
+Check out the {kibana-ref}/indexing-geojson-data-tutorial.html[Indexing GeoJSON data tutorial].
+
+In 7.5, Maps also introduces these new features:
+
+* Styling by date and time field, which is good for tracking time 
+series data and for highlighting newer data over older records.
+* Document sorting to ensure that your most important data is on top of the map.
+* A new tooltip design with support for drag-drop field sorting and image embeds.

+[[api-keys-7.5]]
+=== A new UI for managing API Keys 
+
+Our new API keys UI allows cluster administrators to view and invalidate 
+all API keys, and users to view and invalidate their own keys. 
+API keys are is especially useful when working with automated scripts, 
+or workflow integration with other software. For example, you can use API 
+keys to automate the ingestion of new data from remote sources, 
+without live user interaction.  See {kibana-ref}/api-keys.html[the documentation] for more details.

+[[snapshot-retention-7.5]]
+=== Automatic deletion of snapshots
+
+When creating a snapshot lifecycle policy with our 
+*Snapshot and Restore* UI, you can now optionally configure a retention period. 
+This feature enables you to automate the deletion of your snapshots, 
+reducing the need for manual cleanup while allowing for retention of only the 
+most relevant and recent snapshots. For example, you might define a 
+policy that deletes snapshots older than thirty days, always keeps 
+the latest five snapshots, and deletes the oldest snapshot if more than 50 
+are present. See {ref}/slm-retention.html[Snapshot lifecycle management retention] 
+for the full documentation.
