Asset CleanUp Pro Performance WordPress Plugin 1.2.5.9

* 'Remove All "generator" meta tags?' improvement: Higher accuracy in removing meta tags with various custom attributes within them
* If 'Remove "REST API" link tag?' is enabled, the /wp-json/ reference is also removed from the "Response headers" when accessing the page via remove_action()
* Compatibility with "X" theme & "PRO" website creator (Theme.co): whenever the editor is ON, no unloads or any other changes to the HTML source (including minification) are performed to make sure the editor is loading its files and works smoothly
* Compatibility with "Redis Object Cache" plugin: The global variable $wp_object_cache is no longer used and it's replaced with a custom solution
* Compatibility with "404page – your smart custom 404 error page" plugin and similar plugins that are making pages as 404 customizable ones
* For debugging purposes, the admin can use /?wpacu_no_cache to view how the website would load without the CSS/JS cache applied
* Fix: Avoid deprecated error notice when a non-static function was called as being static
* Fix: Avoid "Warning: DOMDocument::loadHTML(): Empty string supplied as input" in some situations when the HTML source is parsed
* Fix: "style>" was showing up at the top of the page when Inline CSS was enabled when the fetched file (for inlining) was empty or only had comments in it

* For maximum compatibility, any inline CSS/JS code associated with a handle (e.g. added via wp_add_inline_style() & wp_add_inline_script()) is automatically appended to any file that is added to a combined CSS/JS file
* Added more elements to the debug area (accessed via /?wpacu_debug to show how much time it takes to load them); Also, the time calculating to dequeue CSS/JS handles wasn't accurate, this has been fixed
* Prevent certain DOMDocument calls (which can be slow on large HTML documents) when they are not necessary (e.g. when preloading CSS stylesheets and the RegEx which is faster can do the same task with the same accuracy)
* If Minify STYLE/SCRIPT (inline) tags are enabled, then make that content larger than 40KB are cached as so far the minify was done on every page load and for very large inline tags, it would have used more resources and time to render the HTML output
* In some cases, the PHP function strtr() has proven to be faster than str_replace() to make replacements, thus it has been applied to some methods that are dealing with the alteration of the HTML source
* Fix: In some situations, the fetching of the CSS/JS list got stuck without loading anything due to a fetching speed filter that disabled all other plugins apart from Asset CleanUp Pro to load on the last AJAX call

* Added contract / expand asset row for hardcoded assets so the admin can contract them if they take too much space and some of them will likely never be unloaded in any page
* 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)
* 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'
* While the CSS/JS assets are fetched prevent extra performance plugins from triggering their optimisation for CSS/JS/HTML as the action is irrelevant and uses resources during the fetching of the assets for the admin
