Lightbox 2.1 added a new HTML DOM parser. However due to a memory leak in PHP 5.1.x and 5.2.x and an improper use of the garbage collection routine a rather glaring bug was introduced in which all content was replaced by information about the programmatic object. Version 2.2 addresses this issue and correctly cleans up the memory and outputs the content as a result. The issue was partly my fault and partly PHP 5.1.x/5.2.x fault.
Version 2.2. also reintroduces PHP 4 functionality for those of you still stuck with PHP 4 which is long since (as of 8/8/8) unsupported by the PHP developers.
See after the jump for the change log details.
