+
+- [tile mode][static mode] Clear render data for the new still image request ([#16318](https://github.com/mapbox/mapbox-gl-native/pull/16318))
+
+  The new `keepRenderData` map options flag is added to control whether render data shall be kept between `renderStill()` calls.
+
+### 🐞 Bug fixes
+
+- [tile mode][static mode] Clear render data for the new still image request ([#16318](https://github.com/mapbox/mapbox-gl-native/pull/16318))
+
+  If the `keepRenderData` map options flag is unset all render data is cleared between `renderStill()` calls, thus stale tiles from the previous `renderStill()` call are never shown.
+
+### 🏁 Performance improvements
+
+- [tile mode][static mode] Clear render data for the new still image request ([#16318](https://github.com/mapbox/mapbox-gl-native/pull/16318))
+
+  If the `keepRenderData` map options flag is unset all render data is cleared between `renderStill()` calls, thus saving memory being used.
