     <PackageReleaseNotes># 2.0.2
-* Fixed calling convention related execution engine exception for the Windows platform.
+* Fixed calling convention of unmanaged function pointers. (Thanks NogginBops!)
+* Allocating a GC handle to StbiStreamWrapper class and passing it as userdata into stbi in order to prevent
+  the object from being prematurely collected by the garbage collector when optimizations are enabled in Release mode.
 
 # 2.0.1
 * Enabled optimizations across the board for native and managed assemblies.
