PHP code still works; regardless of whether the plugin has been added to. It’s passed compatibility with PHP 7.2 and works with WP in May 2018, so no reason to stop using it, unless it no longer works with your other plugins or some major change to WP.
You can test it with the BETA of Gutenberg by installing the Gutenberg beta plugin, if that is a concern.
We’ll keep using it here, or roll it into our own plugin for future use.
The ‘code’ will work as long as WP utilizes the elements being over-ridden. ??
Again, for anybody worried – it works with PHP 7.2 latest version as of May 2018.
I am still using another plugin from 2010, long abandoned, which we added a single line fix for PHP 7; still works flawlessly. (Most plugins are simple functions to over-ride something in WP which should be a built-in feature to begin with, as this one does.)
Awesome plugin. Hope it keeps working with WP 5.0 !!!
