+**1.5.1**
+- Increase serialize version of AssetToFileDependencyCache because of dependency order change
+- Fixed possible StackOverflowException with very huge dependency trees and ShowAdditionalInformation option being enabled
+
 **1.5.0**
 - AssetDependencyCache update is now a lot faster due to improved reflection code
 - "Calculating all node sizes" step is now faster since it now only calculates reachable nodes
