CHANGELOG.md

 ## [unreleased][]
 
 ### Added
+-   Added new build system (pythonnet.15.sln) based on dotnetcore-sdk/xplat(crossplatform msbuild).
+    Currently there two side-by-side build systems that produces the same output (net40) from the same sources.
+    After a some transition time, current (mono/ msbuild 14.0) build system will be removed.
+-   NUnit upgraded to 3.7 (eliminates travis-ci random bug)
 -   Added `clr.GetClrType` (#432, #433)
 -   Allowed passing `None` for nullable args (#460)
 -   Added keyword arguments based on C# syntax for calling CPython methods (#461)
