-Date: Thu, 13 Apr 2017 15:02:53 +0200
-Subject: [PATCH] Add Node 7.x aka V8 5.2+ support
-
-* Use WeakCallbackInfo instead of WeakCallbackData
-* Use GetPrivate instead of GetHiddenValue
-* Adopted new signature for SetWeak to support destructor calling
-* SetAccessor deprecation fixed
-* Proper version checks where applicable
-
-Upstream-Status: Submitted [https://github.com/swig/swig/pull/968]
