Been procrastinating on updating from PHP 7.3 to 7.4. How some very complicated (developed over 7 years) PHP code and I subscribe to the saying "if it's not broke, don't try to fix it." Going to PHP 8 is going to be folded into going from Centos 7 to Almalinux 8 as that will be a major endeavor that will take days of testing. But in the meantime, I was thinking of at least going to PHP 7.4. Wondering if there are any gotcha's to watch out for such as functions that were deprecated in 7.3 and then don't work in 7.4?
