 ## [unreleased][]
 
 ### Added
+-   Added support for embedding python into dotnet core 2.0 (NetStandard 2.0)
 -   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.
