   * GitHub Actions CI build added for our Python code (#165)
   * VS2017 Debug x64 build of ApprovalTests.cpp.StarterProject gave "C1128: number of sections exceeded object file
     format limit: compile with
     /bigobj" ([ApprovalTests.cpp.StarterProject#16](https://github.com/approvals/ApprovalTests.cpp.StarterProject/issues/16))
+  * Removed undocumented ability to verify `std::wstring` and `wchar_t*`. This gave compiler warnings on C++17 and above, and did not work on Visual Studio. (#154, which contains the deleted code for future reference)
