I was curious when various Perl variables showed up, so I started diving through perlvar and perl*delta. Ignoring those that were already there in Perl 4, I have so a draft list. It's a bit dodgy because some of the variables existed before they were documented, but I'm really interested in the point where they became supported variables (so, I also don't care about blead versions):

Does anyone have any corrections or predictions for 5.14? :)
