<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.
