+## MSVC/Clang-Cl Argument Changes/Cleanup
+
+* "Disable Debug" (`/Od`) is no longer manually specified for optimization levels {`0`,`g`} (it is already the default for MSVC).
+* "Run Time Checking" (`/RTC1`) removed from `debug` buildtype by default
+* Clang-CL `debug` buildtype arguments now match MSVC arguments
+* There is now no difference between `buildtype` flags and `debug` + `optimization` flags
+
+The /Od flag has been removed, as it is already the default in the MSVC compilers, and conflicts with other user options.
+
+/RTC1 conflicts with other RTC argument types as there are many different options, and has been removed by default.
+Run Time Checking can be enabled by manually adding `/RTC1` or other RTC flags of your choice.
+
+The `debug` buildtype for clang-cl added additional arguments compared to MSVC, which had more to do with optimization than debug. The arguments removed are `/Ob0`, `/Od`, `/RTC1`. (`/Zi` was also removed, but it is already added by default when debug is enabled.)
+
+If these are important issues for you and would like builtin toggle options, 
+please file an issue in the Meson bug tracker.
