It would be nice if the documentation for parameters include a new field for the version the parameter was first introduced.
Sometimes, support or forum users suggest using a parameter to solve an issue or gather more info but that parameter may not exists in the old version of SM/SMAX that a user is using. If this info is easily found in the online help, that would be very useful.
It may be hard to go through current parameters to check their date of introduction. As a suggestion, start including this “introduced in version” field only for the next set of new parameters.
