Asset CleanUp: Page Speed Booster - Version 1.3.6.6

Version Description

• The caching of a file is re-built based on the filemtime() value as developers often forget to update the value of the "ver" (/?ver=) after updating a CSS/JS file's content
• When listing the loaded stylesheets (LINK tags), make sure to print the "media" attribute if it's different than "all" so the admin will be aware if that particular CSS is meant for mobile or other devices (e.g. to save time from going through the HTML source code and check it out there)
• Files loaded from "/wp-content/bs-booster-cache/" are not minified/combined (as they are already minified) to avoid getting a large caching directory (often having lots of GB)
• Prevent certain JavaScript code containing random strings such as nonces (e.g. CDATA one) from being added to the combined JS files to avoid the plugin generating lots of JS combined files that would increase the total disk space by writing to the caching directory
• New ways to sort the list of the CSS/JS files that are managed: "Grouped by their size (sorted in descending order)", "Grouped by having at least one rule & no rules", "All enqueues in one list"
• At least PHP 5.6 is now required (anything below that and the plugin won't activate). Official support for PHP 5.6 ended on December 31st, 2018. Unless you really have to use it (e.g. old code that won't work with never PHP version), it's strongly recommended that you update to PHP 7+ as it's much faster & uses less resources than older PHP versions, not to mention the improvement in terms of security vulnerabilities & bugs - Read more about unsupported PHP branches: https://www.php.net/eol.php
• Fix: "Combine CSS" was not working, unless "Combine JS" was also enabled
