-See also <<breaking-changes>> and <<release-notes-6.3.0>>.
+Each release of {kib} brings new features and product improvements.
+Here are the highlights of the features that were added in 6.3 and
+how the user experience improved.
+
+Refer to the <<release-notes-6.3.0,6.3.0 Release Notes>> for a list bug
+fixes and other changes.
+

+=== License management and {xpack} code
+
+Starting with version 6.3, all of the free {xpack} features, such
+as monitoring, tile maps, Grok Debugger, and Search Profiler,
+ship with the default distribution of {kib}.  When you install {kib},
+it generates a Basic license with no expiration date.
+
+You can view the status of your license, install a new license,
+or start a 30-day trial of https://www.elastic.co/subscriptions[Platinum features]
+in *Management > License Management*.
+The trial enables you to try out features such as
+security, machine learning, alerting,
+graph capabilities,
+and more.
+
+At the end of the trial period, your license reverts to a Basic license.
+To continue using the Platinum features, you can purchase a
+https://www.elastic.co/subscriptions[subscription] and update
+you license.

+=== Autocomplete and simple syntax
+
+{kib}'s experimental autocomplete and simple syntax features
+can help you create queries. To turn on these features,
+click *Options* on the right of the query bar
+and opt in.
+
+Once enabled, just start typing in the query bar,
+and you'll get suggestions for fields,
+values for keyword fields, and query operators.
+For information on the simplified, easier-to-use syntax, see
+<<kuery-query, {kib} Query Language Enhancements>>.
+
+
+
+[float]
+=== Return to recently viewed content
+
+{kib} now keeps track of your recently viewed
+items so that you can easily get back to them.  Here's how:
+
+* Your last five recently viewed items are listed
+at the top of the Home page. A dropdown menu
+provides access to views further back in
+history.
+
+* Your recently selected time ranges are listed
+in the Recent tab in the time picker.
+
+
+[float]
+=== Smaller grid dimensions for dashboards
+
+{kib} 6.3 gives you more control over panel sizes when
+creating a dashboard.  This gives you better control over
+the layout.  Here are the changes:
+
+* The grid height of the dashboard was decreased from 100 pixels to 20
+pixels.
+
+* The number of columns in the grid was increased from 12 pixels to
+48 pixels.
+
+
+[float]
+=== Chained Input Controls
+
+The <<controls,Controls>> visualization now enables you to chain dropdown menus.
+When chained, the value selected in the first menu
+filters the terms in the second menu. A chained menu
+is only enabled when its ancestor controls have values.
+
+[float]
+=== Index Management UI
+
+The new <<managing-indices,Index management>> UI enables you to view index settings, mappings,
+and statistics and perform management operations. These include refreshing,
+flushing, clearing the cache, merging segments, and closing or deleting indices.
+The UI provides a convenient way to perform bulk operations on multiple indices.

+=== Interactive map support in Vega
+
+You can now use the <<vega-graph, Vega visualization plugin>> to overlay
+a geographic data visualization on a map.  To start a Vega visualization,
+open the Visualization application and click the *+* button. Scroll to the
+*Others* section and select *Vega*.
+
+[float]
+=== Easily enable monitoring from the UI
+
+In 6.3, the first time you open {kib} monitoring, data collection is disabled,
+and you'll be prompted to turn it on. If you have permission to turn
+on data collection, and there is data in the cluster, {kib} displays the
+monitoring dashboards. If {kib} can't activate monitoring, you'll get a message
+with suggestions to try.
+
+[float]
+=== Enhancements to the console
+
+The autocomplete function in the Dev tools console
+is now expanded to use {kib} and Basic {xpack} APIs.
+This ensures that autocomplete covers the same use cases as the query bar
+and other areas of {kib}.
+
+[float]
+=== APM Watcher Assistant
+
+The new *Watcher assistant* UI enables
+you to easily generate watches that alert you to errors in
+your APM data. You can specify an error group occurrence threshold
+and a trigger schedule. At a fixed interval (minutes/hours/daily),
+you will get an email or slack notification if
+an error group has more than the specified number of occurrences.
