Changelog do Asset CleanUp: Page Speed Booster PRO

Melhoria

• Separate effective asset unloads from rules that had no effect on the current page, with inactive rules grouped by asset type.
• Rule Management: "Overview" is now the recommended place to review and manage bulk rules, including dormant rules left behind by deleted pages or deactivated plugins. Removed "Bulk Changes" from the top navigation, WordPress sidebar, and Admin Bar. The legacy page remains accessible through its direct URL and existing bookmarks: /wp-admin/admin.php?page=wpassetcleanup_bulk_unloads
• The "CSS/JS Manager" and Admin Bar now explain when "Page Options" disable optimizations, including CSS/JS unload rules. Admin Bar warnings identify disabled features, while clearer descriptions, dimmed overridden options, and quick links make these settings easier to understand.
• Debugging "/?wpacu_debug": Added temporary "Page Options" overrides without changing saved settings. Debugging controls now update their availability and distinguish global restrictions, Page Options overrides, and missing rules.
• Debugging "/?wpacu_debug": Added per-file CSS/JS optimization details explaining content changes, unchanged results, exclusions, failures, and cache decisions. Multiple optimization reasons can be shown for the same file.
• Overview: Added navigation entries for "Page Options" and "Special Settings", clarified page overrides, and dimmed redundant options.

Melhoria

• Reduced Google Fonts browser discovery traffic by running the collector for approximately 2% of public browsers while preserving duplicate protection for known configurations.
• Made the Google Fonts discovery REST endpoint compatible with sites where WordPress pretty permalinks or REST rewrite rules are unavailable.

Melhoria

• Live Debugging: Redesigned the frontend Live Debugging interface (/?wpacu_debug) with theme-independent styling, clearer temporary controls, searchable plugin selection, expandable request and performance details, unavailable-option indicators, and a responsive floating action bar.
• Data Compatibility: Hardened handling of legacy or unexpectedly formatted stored plugin data, preventing warnings or failures when settings and rules are already stored as arrays instead of JSON strings.
• Import/Export: Added stricter structural validation before importing settings and rules, preventing malformed configuration data from being partially imported.
• Plugin Icons: Improved WordPress.org plugin icon fetching and cache recovery so missing icons can be downloaded again instead of remaining permanently replaced by the default icon.
• Access Control: Access-control settings are now hidden from delegated plugin managers who are not permitted to manage plugin access.
• PHP 8.5: Avoided the deprecated curl_close call on modern PHP versions.
• Removed legacy CSS and obsolete browser-specific declarations and performed related internal cleanup.

Melhoria

• JavaScript Optimization: Improved handling of modern JavaScript, including module/nomodule scripts and scripts using integrity, nonce, crossorigin or referrerpolicy attributes, preventing unsafe combine, inline or Match Media transformations.
• Resource Loading: Hardened image attribute and lazy-loading rule validation, improved compatibility with rules saved by older versions and fixed edge cases where attributes such as src could be confused with data-src.
• CSS/JS Manager Settings: Redesigned the manager preferences area with clearer navigation and explanations, better-organized controls for management locations, access, list appearance and optimized-file cache settings.
• Settings and CSS/JS Manager: Added unsaved-change counters and persistent save areas, making modified settings and asset rules easier to review before saving.
• Dashboard Reliability: Improved AJAX validation, authorization and failure recovery across several Dashboard actions, including safer handling of invalid, expired or interrupted requests.
• Tools / Storage: Added a detailed overview of generated CSS/JavaScript storage, including directory paths, file counts, disk usage, write status and filtering between optimized assets and supporting files.
• Tools / Debugging: Redesigned the troubleshooting area with clearer diagnostic modes, copyable test URLs and protected PHP error-log downloads.
• Tools / Reset: Added more granular reset options for Critical CSS and front-end or Dashboard Plugins Manager rules, with clearer confirmation, deletion summaries and partial-failure reporting.
• Tools / Uninstall: Cleanup results are shown on the Plugins page and partial filesystem failures are reported instead of returning a false success. Plugin settings are not recreated after cleanup.
• Multisite Uninstall: Network-shared user access data and the Pro MU-plugin loader are preserved while Asset CleanUp Pro remains active on another site in the network.
• Privacy, Dashboard Announcements: Remote announcements are now disabled by default and require an explicit administrator opt-in.

Melhoria

• Plugins Manager: Improved settings reliability and group expand/collapse controls, including clearer state handling and recovery when an AJAX request fails.
• Dashboard CSS/JS Manager: When a selected URL redirects to another allowed internal URL, explicit confirmation is required before loading assets from the final destination. The redirected URL remains visible after loading. Redirects from non-homepage contexts to the homepage remain blocked.
• Admin Experience: Major UI/UX refresh across Settings, Help, Getting Started, Critical CSS and multiple vertical/horizontal tab sections, including clearer layouts, spacing, typography, accessibility and content organization.
• Interface Controls: Added a choice between the enhanced WPACU controls and standard browser-native form controls across supported admin areas.
• Reduced expensive processing during updates and moved stale hardcoded-asset information cleanup to a scheduled maintenance task, particularly benefiting multilingual sites and installations with many saved rules.
• Reorganized Critical CSS and Plugins Manager styles.

Melhoria

• Plugins Manager: Hierarchical child pages, such as /parent/child/, are now correctly detected by unload rules and load exceptions.
• Plugins Manager: Added a notice when rules are preserved for inactive or not-installed plugins, with direct access to review them in the Overview.
• WPML: Exact singular-page unload rules and load exceptions now match translated permalinks at the early MU-plugin stage, including translated slugs, language directories, query-string languages, and separate language domains. The stored URL map is refreshed when relevant slugs, parent paths, permalink settings, or WPML URL settings change.
• Critical CSS: Critical CSS can now be managed with the same granular page-type coverage as the CSS/JS Manager, including individual posts, pages, custom posts, taxonomy terms, author archives, date archives, search results, 404 pages, and custom post type archives.
• CSS/JS Manager: Assets for virtually any supported page type can now be managed directly from the WordPress Dashboard, including archive pages that previously required front-end management.
• Overview: Added quick section navigation, an optional sticky navigation bar, and back-to-top links.

Melhoria

• Overview: Made managing and cleaning existing rules significantly easier, particularly on sites with many optimization changes accumulated over time.
• Admin bar: Added hover details for unloaded CSS/JS assets and plugins, showing the matched unload rule and its relevant value when available.
• Reworked internal RegEx handling and replaced the previous third-party RegEx library with a dedicated lightweight class. This reduces the plugin package size while retaining support for plain-text rules, RegEx rules, and existing legacy patterns.

Melhoria

• Resource Loading: Improved the image-attributes data structure. If you upgrade and later downgrade to an earlier plugin version, image-attribute rules might need to be configured again.
• Resource Loading: Improved how the fetchpriority, loading, and decoding attributes are added to images. Location: "Settings" -> "Resource Loading" -> "Image Attributes". Read more
• Admin bar: Refined hover behavior for nested "Asset CleanUp Pro" submenus to reduce accidental menu closing.
• Refined admin CSS to remain consistent with WordPress 7.0 layout changes.

Melhoria

• Improved asset minification stability (library update)
• "Plugin Announcement" area: Make sure it slides up when it's closed; The font-size has been increased; Fix: "Uncaught TypeError: usort: Argument #1 ($array) must be of type array, string given in [...]/classes/Admin/PluginAnnouncements.php:492"
• "License" area fix: "Uncaught Error: Call to a member function get_error_message on array in [...]/pro/classes/Admin/LicensePro.php:95"

Melhoria

• "License" page: Improved the speed of license verification to prevent timeout errors and avoid confusing the admin into thinking there was an issue with the license.

Melhoria

• "Plugins Manager" Fix: Unload and load exception via user role stopped working if the WordPress version is 6.8 or higher

Melhoria

• Multisite extra compatibility: The structure of the caching directory has been updated, and now each site has its own directory. When the cache is cleared, it will only scan the cached CSS/JS files belonging to the current website, thus saving resources and not affecting in any way the files belonging to other websites. If a switch is made from a single site to a multisite, the structure will be updated and all cache files will be re-created, while the older ones will be cleared after 30 days…
• Hardcoded assets: Highlight the ones belonging to the 'Slider Revolution' plugin to make them easier to identify.

Melhoria

• Optimize JS: If a JS file is loading based on the media query set (e.g. only on mobile view), make sure that any associated inline JS that is printed "after" the main JS file, is triggered only after the main JS file is loading (if the media query matches), and never immediately to avoid JS "undefined" errors in the console and even broken functionality
• Optimize JS: When the WordPress core file "wp-i18n" is unloaded, the SCRIPT tag is replaced with another tag (much ligther) keeping "setLocaleData" and other functions active to avoid JS errors being shown in the console (ideal for websites with just one language)
• Optimize JS: When a JS asset is unloaded and the option 'Ignore dependency rule and keep the "children" loaded' is used, make sure the inline JS associated with the asset is also cleared to avoid any JS errors in the console or even broken page functionality
• Detect an attribute found in a tag without using RegEx (for faster PHP processing)

Melhoria

• WPML compatibility (it works with other similar plugins as well): Make sure that whenever CSS/JS manager is used in the Dashboard, if the domain/subdomain is different (e.g. es.domain.com instead de.domain.com), the assets will be fetched without getting blocked by the browser's CORS policy
• Improvement for plugin's JavaScript files: The main "script" file was split into two files, one containing the most common code that clears the caching and it's used in many pages (e.g. when clicking the clear caching link from the top admin bar), which weights around 6% in comparison with the other files; This way, on many pages, fewer JavaScript code is loaded, thus reducing bandwidth for admin visits, and eliminating any potential conflicts with other JS files belonging to other plugins
• Improvement (admin area): Prevent SweetAlert and extra CSS to load if there's no CSS/JS manager loaded (e.g. edit post area)
• Google Fonts Combine Fix: W3C Validator / 'Error: Bad value for attribute href on element link: Illegal character in query: | is not allowed.' - The character '|' is replaced with '%7C'

Melhoria

• Make sure plugin generated STYLE/SCRIPT inline tags (e.g. from features such as "Inline CSS/JS") have the "type" attribute (unless the theme supports HTML5) / read more:
• Moved "CSS/JS Cache" tab into the "CSS/JS Manager" one and grouped options within the 'CSS/JS Manager' (for better readability)

Melhoria

• Plugin Updater / When using /?wpacu_force_plugin_updater in the Dashboard (e.g. in the "Plugins" page), the cache related to the latest detected version is cleared (e.g. in case the admin has problems updating the plugin, the query string can be used, before re-trying the plugin update)
• "Plugins Manager" - Added the "currency" query string to the list of common strings that are ignored when an early detection is made for the homepage (e.g. www.yoursite.com/?currency=EUR is considered the homepage)

Melhoria

• Updated the external links to the help pages

Melhoria

• Reduce the total number of SQL queries used to obtain information
• Stop triggering PHP code and SQL queries on pages where they are not relevant
• Cache SQL queries that are time consuming, which is ideal for websites with a very large database (e.g. tens / hundred of thousands of users)

Melhoria

• "wpacu_access_role" filter is no longer active (related to the option mentioned above), as it wasn't 100% effective into changing who accesses the Asset CleanUp Pro area
• "Nextend Social Login and Register" plugin compatibility / Make sure the homepage is still detected if the following query string is in the URI: "nsl_bypass_cache"

Melhoria

• When using specific themes, the navigation sub-tabs from the "CSS & JS Manager" were overwritten by the theme's style (added unique references to the HTML classes)
• Clear cache after "Plugin Manager" form is submitted (some plugins might load specific assets, and a cache clearing is recommended)

Melhoria

• Make sure the red background is kept whenever a load exception is unchecked if there was already an unloading rule set (this is more for aesthetics reasons)
• Prevent possible is_file errors whenever minify CSS/JS is enabled
• Whenever the following option is enabled, the META generator tags are stripped faster after being cached: 'HTML Source CleanUp' -- 'Remove All "generator" meta tags?'
• If the menu from the sidebar is not showing up, make sure that "Asset CleanUp Pro" from "Settings" (Dashboard sidebar) is always highlighted, whenever a plugin page is visited
• Change the way the plugin submenu is created to avoid, in some environments, errors such as the following one: "NOTICE: PHP message: PHP Warning: Undefined array key 2 in /wordpress/wp-admin/includes/plugin.php on line 2012"
• Hardcoded assets: When altering any hardcoded asset, make sure that prior to this, only the assets that are needed are fetched to save resources (e.g. if only LINK tags have to be altered, do not fetch at all any SCRIPT tags)

Melhoria

• CSS Minifier Improvement: Specific "var " statements were minified incorrectly in Bootstrap / more:

Melhoria

• Backend Speed Improvement: The plugin processes its PHP code faster, thus reducing the total processing time by ~40 milliseconds for non-cached pages (e.g. backend speed testing plugins such as "Query Monitor" and "Code Profiler" were used to optimize the PHP code)
• "Overview" area: Added the option to clear any rules set for plugins that are deactivated / deleted

Melhoria

• "Plugins Manager": Allow the option to unload a plugin depending on the logged-in user role (e.g. for a "subscriber" that has access to the Dashboard, specific plugins that you know are useless for this type of user, could be unloaded to make the Dashboard load faster)
• CSS/JS manager: When the "src" of a SCRIPT tag or "href" of a LINK tag starts with "data:text/javascript;base64," and "data:text/css;base64," respectively, a note will be shown with the option to view the decoded CSS/JS code
• Added the option to change the way the assets are retrieved ("Direct" as if the admin is visiting the page / "WP Remote POST" as if a guest is visiting the page) from the CSS & JS manager within the Dashboard (for convenience, to avoid going through the "Settings" as it was the case so far)

Melhoria

• Apply "font-display:" CSS property for Google Fonts when they are loaded via Web Font Loader (source:
• Plugin's "License" page: When the information is fetched, make sure the AJAX call is never cached to make sure the latest information is always shown
• Higher accuracy in detecting the "type" and "data-alt-type" attribute before determining if an inline SCRIPT tag has to be minified

Melhoria

• Rank Math & other SEO plugins compatibility: Prevent Asset CleanUp Pro from triggering, thus saving extra resources, whenever URIs such as /sitemap_index.xml are loaded to avoid altering the XML structure or generate 404 not found errors
• Plugins Manager: Make sure the user roles from "If the logged-in user has any of these roles:" are translated into the language chosen for the current admin to avoid any confusion (e.g. if the language chosen in the admin's profile is German, then show "Abonnent" instead of "Subscriber")
• CSS/JS Minifier: Prevent calling @is_file when it's not the case to avoid on specific environments errors such as: "is_file: open_basedir restriction in effect"

Melhoria

• Preload CSS feature: When a .css file is preloaded (Basic), the "media" attribute is preserved if it's not missing and different than "all"
• "Rank Math SEO" & "Premmerce" plugin compatibility: Prevent Asset CleanUp Pro's "Plugins Manager" rules from triggering when the permalinks are updated
• Combine CSS Fix / The preload and stylesheet LINK tags had the same "id" attribute which shouldn't be like that as the "id" should be unique for each HTML element

Melhoria

• Hardcoded assets: When an asset was moved from HEAD to BODY or vice-versa, make sure a notice is placed there in the hardcoded row (when managing the assets) that it had its position changed just like it's done for the enqueued assets
• Removed unused PHP code from specific files

Melhoria

• Hardcoded assets: They can be moved from to and vice-versa just like the enqueued assets
• Hardcoded assets: Can be preloaded, loaded based on the media query, deferred/asynched just like the enqueued assets (for tags with the "src" attribute & tags with the "href" attribute)
• Hardcoded assets' sorting: The assets are now sorted based on the option chosen in "Assets List Layout:" (e.g. if you sort them by their size, you can view the hardcoded assets from the largest one to the the smallest)
• Styling Improvement: Anything from "Settings" related to removal of something (e.g. Google Fonts) has a new style of the switcher (the styled checkbox), now showing a dark red background; This looks the same as the one from the CSS/JS manager for "Unload on this page".
