As a JavaScript implementor, one of the main reasons I refer to MDN is to find out in which version of ECMAscript a particular feature was defined, and in which other versions that definition changed.
MDN used to be excellent for this: the Specifications section would list all the relevant spec versions. But at some point fairly recently (i.e., last year or two) that changed, and the Specifications section seems just to list " ECMAScript (ECMA-262)".
The previous table of versions was extraordinarily useful; the new one is totally useless.
Is there any hope that we can get the former back?
