 - Added a new `\Hyde\Framework\Actions\PreBuildTasks\TransferMediaAssets` build task handle media assets transfers for site builds.
+- The `\Hyde\Facades\Features` class is no longer marked as internal, and is now thus part of the public API.
 
 ### Changed
 - **Breaking:** The internals of the navigation system has been rewritten into a new Navigation API. This change is breaking for custom navigation implementations. For more information, see below.

+### Features class method renames
+
+The following methods in the `Features` class have been renamed to follow a more consistent naming convention:
+
+- `Features::enabled()` has been renamed to `Features::has()`
+- `Features::sitemap()` has been renamed to `Features::hasSitemap()`
+- `Features::rss()` has been renamed to `Features::hasRss()`
+
+Note that this class was previously marked as internal in v1, but the change is logged here in case it was used in configuration files or custom code.
