 Known issues
 ------------
+* Compilation on XE6 and XE7 might fail spuriously. This seems to be related to some bug in the compiler with some non deterministic state.
+* One unit test on XE2 and XE3 fails on Win64 because passing a method parameter is not handled properly by dynamic invokation.
 * Some warnings when compiling for mobile compilers.
 * The deployment of the unit test project might fail for mobile compilers (iOS ARM and Android).
 * Compilation on some older versions for iOS and Android might fail due to compiler bugs.
