 ### New features
 
 * You can now specify CVar overrides via environment variable with the `ROBUST_CVAR_*` prefix. For example `ROBUST_CVAR_game__hostname=foobar` would set the appropriate CVar. Double underscores in the environment variable name are replaced with ".".
+* Added non-generic variant of `GetCVar` to `IConfigurationManager`.
