+## 2.6.0
+
+* Updates the minimum allowed verison of the Google Maps SDK to 8.4, for privacy
+  manifest support.
+    * This means that applications using this package can no longer support
+      iOS 13 or 14, as the versions of the Google Maps SDK that support those
+      versions do not have privacy manifests, so cannot be used in published
+      applications once the new App Store enforcement of manifests takes effect.
+* Includes the Google Maps SDK's [GoogleMapsPrivacy bundle](https://developers.google.com/maps/documentation/ios-sdk/config#add-apple-privacy-manifest-file)
+  manifest entries direct in the plugin, so that package clients do not need to
+  manually add that privacy bundle to the application build.

 ## 2.5.2
 
 * Fixes the tile overlay not correctly displaying on physical ios devices.
