Calls to Markup() or Markup_e() are the case here. :-)

They configure patterns and replacement text or replacement functions to 
be called by PmWiki later, at specific moments of the markup processing.

Here is how it works:

1. Regular expressions with the "/e" pattern modifier are "too old" 
because they have been deprecated in PHP 5.5, and removed in PHP 7.0.

2. Calls to Markup_e(), PCCF(), PPRE(), PPRA() are "too old" when they 
call create_function() which has been deprecated in PHP 7.2 and removed 
in PHP 8.0.

If you run a PHP version that doesn't allow the configuration requested 
by the recipe, in many cases now PmWiki considers that the markup rule 
is "too old" and disables it with the appropriate notification, rather 
than leaving a PHP warning or a crash.

If you run an older PHP version, even recent PmWiki versions should 
work, with older configuration recipes.

As I wrote in my previous email, I have updated the Video5 recipe today. 
The new version should work with PHP up to 8.2.

Feel free to take over the maintenance of this recipe if its authors 
cannot support it and you want to support it. The GNU GPL license chosen
