What is the extended symbolic math toolbox?

In a previous question on this site, when I was typing in the product 'Symbolic Math Toolbox' in that user form, the phrase 'Extended Symbolic Math Toolbox" popped up as a completion suggestion. I googled it but there were no results. So was this just a spurious pop up on the part of Google and/or MathWorks? Or is there an Extended Symbolic Math Toolbox that I need to buy?

It was a product that extended Symbolic Math Toolbox functionality. Many years ago (I don't remember the release offhand) the functionality it provided was either rendered moot or was incorporated into Symbolic Math Toolbox proper. It is neither necessary nor available for recent (relatively speaking; this was a number of years ago) releases.
