 ## Performance improvements
 
 Performance was improved by replacing internal data structures with base .NET types, such as <xref:System.Collections.ObjectModel.ReadOnlyCollection`1>. This minimized allocations in UI automation and file dialogs, and speeding up pixel format conversions.
 
+Enhanced performance by optimizing cache operations, array handling, and migrating font collection loader to managed code.
