of offline packs.
While this method does not limit the space available to offline packs,
data in offline packs count towards this limit. If the maximum ambient
cache size is set to 30 MB and 20 MB of offline packs are downloaded,
there may be only 10 MB reserved for the ambient cache.
This method does not limit the space available to offline packs, and data in
offline packs does not count towards this limit. If you set the maximum ambient
cache size to 30 MB then download 20 MB of offline packs, 30 MB will remain
available for the ambient cache.
This method should be called before the map and map style have been loaded.

* Fixed an issue where an `MGLSymbolStyleLayer.lineDashPattern` value of `{1, 0}` resulted in hairline gaps. ([#16202](https://github.com/mapbox/mapbox-gl-native/pull/16202))
* Improved the performance of loading a style that has many style images. ([#16187](https://github.com/mapbox/mapbox-gl-native/pull/16187))
### Networking and storage
* Downloaded offline packs no longer reduce the storage space available for ambient caching of tiles and other resources. ([#15622](https://github.com/mapbox/mapbox-gl-native/pull/15622))
* Fixed issues where an offline pack would stop downloading before completion. ([#16230](https://github.com/mapbox/mapbox-gl-native/pull/16230), [#16240](https://github.com/mapbox/mapbox-gl-native/pull/16240))
* When an offline pack encounters an HTTP 404 error, the `MGLOfflinePackUserInfoKeyError` user info key of the `MGLOfflinePackErrorNotification` now indicates the resource that could not be downloaded. ([#16240](https://github.com/mapbox/mapbox-gl-native/pull/16240))
### Other changes
* Added the `MGLMapView.minimumPitch` and `MGLMapView.maximumPitch` properties to further limit how much the user or your code can tilt the map. ([#208](https://github.com/mapbox/mapbox-gl-native-ios/pull/208))
* Fixed issues where an offline pack would stop downloading before completion. ([#16230](https://github.com/mapbox/mapbox-gl-native/pull/16230), [#16240](https://github.com/mapbox/mapbox-gl-native/pull/16240))

* The `-[MGLMapSnapshotter cancel]` method no longer calls the completion handler passed into `-[MGLMapSnapshotter startWithCompletionHandler:]`. ([#209](https://github.com/mapbox/mapbox-gl-native-ios/pull/210))
* Fixed an issue where the `MGLMapSnapshotter.loading` property always returned `NO`, even while loading a snapshot. ([#209](https://github.com/mapbox/mapbox-gl-native-ios/pull/210))
* Improved performance when continuously animating a tilted map. ([#16287](https://github.com/mapbox/mapbox-gl-native/pull/16287))
* Fixed a memory leak when zooming with any options enabled in the `MGLMapView.debugMask` property. ([#15179](https://github.com/mapbox/mapbox-gl-native/issues/15179))
* Added the `-[MGLOfflineStorage preloadData:forURL:modificationDate:expirationDate:eTag:mustRevalidate:completionHandler:]` method for determining when the data is ready to retrieve from the cache. ([#188](https://github.com/mapbox/mapbox-gl-native-ios/pull/188))

* Ideographic glyphs from Chinese, Japanese, and Korean are no longer downloaded by default as part of offline packs; they are instead rendered on-device, saving bandwidth and storage while improving performance. ([#14176](https://github.com/mapbox/mapbox-gl-native/pull/14176))
