No, my copy was published in 1992 and is the first edition. https://en.wikipedia.org/wiki/ Structure_and_Interpretation_of_Computer_Programs lists Chapter 4: Metalinguistic Abstraction 4.1 The Metacircular Evaluator 4.2 Variations on a Scheme – Lazy Evaluation 4.3 Variations on a Scheme – Nondeterministic Computing 4.4 Logic Programming mine has Chapter 4: Metalinguistic Abstraction 4.1 The Metacircular Evaluator 4.2 Variations on a Scheme – Lazy Evaluation 4.3 Packages 4.4 Logic Programming 4.5 Implementing the Query System Chapter 2 drops the Symbolic Data section. Chapter 5 is reordered but I think all the discussion is there. The only index hit on continuation is a half page on 'continuator descriptors', 'next', 'return' and a jump to a named entry point like a goto in C. After doing the exercises that winter I had no reason to follow the development of Scheme so I don't know if 'call-with-current-continuation' was added or if the authors didn't think it important. It isn't in the index either.
