<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Don't do a strict taxonomy check in `get_category_link()`.
Prior to version 4.9, a quirk in the implementation of `get_term()` caused
`get_category_link( 123 )` to fetch the taxonomy archive link for term 123
even if 123 is not in the 'category' taxonomy. The quirk was fixed in <a href="https://core.trac.wordpress.org/changeset/40979">[40979]</a>;
see <a href="https://core.trac.wordpress.org/ticket/40671">#40671</a>. This bugfix introduced a regression for theme authors who were
expecting the old behavior.
By lifting the 'category' restriction, we allow the template function to work
in the old way.

Fixes <a href="https://core.trac.wordpress.org/ticket/42717">#42717</a>. See <a href="https://core.trac.wordpress.org/ticket/42771">#42771</a>.</pre>
