This major release is pretty much a rewrite of the old version whilst retaining all old functionality. The original version of the plugin was contained within one file and used a single class with static methods. Following the separation of concerns principle, I’ve split certain functionality into its own classes and files and generate instances of classes rather than using static methods. This was mainly for testing, performance and scalability.

Most users will be able to upgrade to v2 without a hitch, however if you used the old version and used the static methods in your theme code like

PostLockdown::is_post_locked($post_id)

then you’ll need to update that code to the following to use v2:

$GLOBALS['postlockdown']->is_post_locked($post_id);

If you’re going to use the instance more than once then it’d make sense to declare the global like global $postlockdown so you don’t need to use the $GLOBALS array:

<?php
global $postlockdown;

$postlockdown->is_post_locked($post_id);
$postlockdown->is_post_protected($post_id);
