+breaking:
+  title: Change most Elasticsearch timeouts to 429 response instead of 5xx
+  area: REST API
+  details: When a timeout occurs in most REST requests, whether via a per-request timeout, or a system default, the
+    request would return a 5xx response code. The response code from those APIs when a timeout occurs is now 429.
+  impact: Adjust any code relying on retrying on 5xx responses for timeouts to look for a 429 response code and
+    inspect the response to determine whether a timeout occured.
+  notable: false

-An alias is a secondary name for a group of data streams or indices. Most {es}
+An alias points to one or more indices or data streams. Most {es}
 APIs accept an alias in place of a data stream or index name.
 
-You can change the data streams or indices of an alias at any time. If you use
-aliases in your application's {es} requests, you can reindex data with no
-downtime or changes to your app's code.
+Aliases enable you to:

+* Query multiple indices/data streams together with a single name
+* Change which indices/data streams your application uses in real time
+* <<docs-reindex,Reindex>> data without downtime
