Asset CleanUp Pro history.

* **Improvement:** Reduced Google Fonts browser discovery traffic by running the collector for approximately 2% of public browsers while preserving duplicate protection for known configurations. * **Improvement:** Made the Google Fonts discovery REST endpoint compatible with sites where WordPress pretty permalinks or REST rewrite rules are unavailable. * **Fixed:** Browser discovery is now disabled by default, preventing discovery REST traffic on new or previously unsaved configurations until the feature is enabled.

* **Added — Google Fonts:** Added local hosting for Google Fonts, allowing detected stylesheets and font files to be downloaded, validated and served from the local cache. * **Added — Google Fonts:** Added granular font removal, allowing specific Google Font families, weights and styles to be removed while keeping the remaining fonts unchanged.

* **Added — Font Preload Audit:** Added a browser-assisted audit for manually preloaded Local and Google Fonts. The audit checks representative pages in desktop and mobile viewports, identifies duplicate, invalid or unnecessary site-wide preloads and provides conservative cleanup recommendations without removing the fonts themselves. * **Added — Critical CSS:** Added a global control directly in the Critical CSS Manager to temporarily pause or resume all Critical CSS output while preserving the existing rules. * **Added — Tools / Storage:** Added a read-only Database Map showing where Asset CleanUp stores settings, optimization rules, metadata, transients and Pro-specific data. * **Added — Tools / Uninstall:** Added a dedicated, explicitly confirmed action for removing all Asset CleanUp data before uninstalling the plugin, including settings, optimization rules, metadata, transients, license data and generated cache files. * **Improved — 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. * **Improved — 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`. * **Improved — 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. * **Improved — Settings and CSS/JS Manager:** Added unsaved-change counters and persistent save areas, making modified settings and asset rules easier to review before saving. * **Improved — Dashboard Reliability:** Improved AJAX validation, authorization and failure recovery across several Dashboard actions, including safer handling of invalid, expired or interrupted requests. * **Improved — 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. * **Improved — Tools / Debugging:** Redesigned the troubleshooting area with clearer diagnostic modes, copyable test URLs and protected PHP error-log downloads. * **Improved — 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. * **Improved — 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. * **Improved — 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. * **Fixed — Plugin Rules:** Fixed request-context detection on sites using plain permalinks, preventing homepage, search, author, date and taxonomy requests from being incorrectly treated as the same context. * **Fixed — Multisite Plugins Manager:** Improved detection and handling of network-active plugins across Plugins Manager rules and WPACU internal requests. * **Fixed — Dashboard CSS/JS Manager:** No longer reports a false external redirect or fails to fetch assets when WordPress runs on a non-standard port (e.g. localhost:8888) * **Fixed — Usage Data Settings:** Fixed an undefined variable warning in the usage-data disclosure panel. * **Fixed — CSS and JavaScript:**: Combining now works when minification is disabled. * **Fixed — Upgrade Compatibility:** Recently introduced access-control settings now receive their correct disabled or empty-list defaults when upgrading from older versions, preventing blank fields or unexpectedly enabled checkboxes. * **Privacy — Dashboard Announcements:** Remote announcements are now disabled by default and require an explicit administrator opt-in. * **Security — Remote Asset Handling:** Further hardened remote asset retrieval and redirect validation, including safer handling of dynamically loaded resources and restricted redirect behavior. * **Security — License Administration:** Removed an unsafe legacy GET-based license-status workaround and retained the protected POST-based recovery action. * **Security — Plugin Updater:** Replaced remote PHP deserialization with native JSON collection validation. * **Security — License Server Output:** Added strict allowlist sanitization for promotional HTML returned by the license server.
