README

Invalidate the browser cache of CSS e JS files loaded via wp_enqueue_script and wp_enqueue_style.

The cache can be invalidated in one of two ways;

• statically, specifying a fixed value for the ver query parameter,
• dynamically, setting 'ver' with the timestamp of the last file change (uses filemtime()).

You need to choose the desired way at the asset level configuring the $this->assets array in the main class.
