Asset CleanUp: Page Speed Booster - Version 1.3.6.1

Version Description

• Increased the speed of unloading (dequeueing) styles & scripts by ~40ms (caching is used to avoid calling the same PHP code during several action hooks)
• Higher accuracy in stripping 'before' and 'after' associated inline SCRIPT after adding the content to the JS combined file
• When combining JS content, make sure to extract the right relative path to make it combinable if a local file is loaded and it starts with // in the "src" attribute
• Show confirmation message when unloading specific files that are very likely needed such as jQuery, Backbone & Underscore libraries
• Alert the admin when there are unload rules from inactive plugins on pages such as "Bulk Changes" & "Overview"
• Keep Dashicons loaded if the toolbar (top admin bar) is shown
• Prevent front-end optimisation code from triggering while the CSS/JS is fetched, thus saving resources and improving the speed of retrieving the assets
• Optimised the plugin to use less calls to MinifyCss & MinifyJs for hardcoded assets reducing considerably the resources used (sometimes timeout errors are generated in hosts with a lower resources allocated)
• When a plugin page (e.g. "Settings") is visited within the Dashboard, trigger a maintenance script that will remove inactive handle data information (from handles without any rule attached to it, often from deleted plugins no longer used) from the "wpassetcleanup_global_data" option value (from options table), thus making it lighter
• In many hosting environments, the total number of fields submitted is maximum 1000 (set by default in php.ini); The total number of fields that were sent have been reduced (e.g. hardcoded assets information) as they are only enabled via JavaScript whenever they are relevant to make sure there are less fields sent (to void partial submit and missing data as a result in case the admin has difficulties increase the default 1000 in php.ini)
• Do not automatically store hardcoded assets info when the CSS/JS manager list is loaded; Instead, store it IF there's a rule attached to it in order to make the contents of the "wpassetcleanup_global_data" option smaller in size (for a lighter database & faster MySQL queries)
• Clear plugin's cache via AJAX after "Settings" is updated within the Dashboard (this is more effective then clearing it when the page reloads as it could take some time to clear the cache if there are lots of files stored there)
• Whenever Asset CleanUp's caching is cleared, the Autoptimize (if enabled) caching is also cleared via AJAX (in an asynchronous way) to avoid any broken CSS/JS (rare cases) even for short time
• Trigger certain actions (to save database & disk space) when the plugin is deactivated: Clear all its transients from the database & Remove the caching directory if it doesn't have any more CSS/JS; If all the plugin's changes were cleared via "Tools" -> "Reset", then deactivating the plugin will completely clear any of its traces
• The plugin's own files that are needed for the plugin's functionality (they are only loading for the logged-in admin), are loaded asynchronously (CSS) and deferred (JS) to ensure the admin doesn't load them as render-blocking especially when managing the pages in the front-end view
• The combined CSS tags can now be altered for any reason via add_filter() through the 'wpacu_combined_css_tag' tag name, just like the combined JS tags are via 'wpacu_combined_js_tag'
• Fix: Remove request to non-existent CSS file within the Dashboard that generated a 404 Not Found error in the browser's console (harmless, but confusing)
