scirpting/include/amxmodx_version.inc:
Code:
#define AMXX_VERSION_NUM 190
It doesn't make sense if it says something else for you if you updated correctly. Even if the compiler isn't updated, it should still output 190 because it reads from the include files. The version is not built in the compiler itself.
I think you're compiling in a completely different folder from the one you downloaded.
