No, this has always been the rule.  However, the rule used to have one 
exception, namely that at the end of a word and before a consonant you 
could only have ß, even if the vowel was short.  It is only this 
exception (which was based on long ſ in blackletter and therefore quite 
obsolete) that was abolished in the 1998 spelling reform.

Best wishes,
