* I have assumed the 1994 APL2 manual has no primitive differences from 1984 ("Summary of Changes" there backs this up) and that all the primitives there but not in earlier APLs were introduced by APL2. As I don't know when Dyalog implemented Find or Depth it's possible it implemented these first. | * I have assumed the 1994 APL2 manual has no primitive differences from 1984 ("Summary of Changes" there backs this up) and that all the primitives there but not in earlier APLs were introduced by APL2.

* NARS2000 dates come from its wiki revision history. It's possible some primitives were implemented substantially before they were documented, but because the wiki was updated continuously I think it probably kept track. | * NARS2000 dates come from its wiki revision history.
