Hmm. Good call out. It was a poor practice on my part to use link there since it’s a built-in. CGI has been a moving target for awhile which I actually dislike… but, active maintenance is better than bit rot even when one disagrees on code direction.

# CGI -> 3.63
perl -MCGI=link -le 'print link({-href=>"/",-rel=>"stylesheet"})'
<link href="/" rel="stylesheet" />

# CGI -> 4.28
perl -MCGI=Link -le 'print Link({-href=>"/",-rel=>"stylesheet"})'
<link href="/" rel="stylesheet" />

Changes file says it was “various beta versions” / 2.37 when it was changed, but it wasn’t really in until some point between the two above.
