Changelog
= 0.8.3-beta.rc – 2026-01-14 =
IMPROVED: In the CSS Optimization section, the optimization type is now correctly labeled as CSS Loading Method.
IMPROVED: In the Critical CSS Generation section, a new option allows choosing between Inline CSS and File-based delivery. Each method has its own advantages and disadvantages. Critical CSS accuracy ranges between 30–70%.
IMPROVED: In the Image Optimization section, the logic for Priority Hints has been refined.
IMPROVED: In the Font Optimization section, added the ability to define custom URLs for font preload. Note that this applies only to locally hosted fonts.
IMPROVED: In the Image Converter section, the logic for converting images to AVIF and WebP has been refined.
IMPROVED: In the Object Cache section, added support for connecting to Redis using ACL authentication (username + password), allowing the use of Redis with ACL (thanks for the suggestion, @Vincent Chan).
FIXED: In the Image Optimization section, the exclusion logic for lazy loading has been corrected for both desktop and mobile versions.
FIXED: Reworked Font Optimization logic for collecting critical fonts to ensure correct preloading.
FIXED: Corrected the loading order of ZiziCache scripts used for collecting CWV metrics.
FIXED: Removed unnecessary autoload entries in the wp_options table during font statistics collection (thanks for the suggestion, @Jakub Schnicel Rezníček).
ADDED: In the Remove Redundancy section, 14 new features have been added with the ability to disable them individually.
EXPERIMENTAL: Added an option to preload jquery.min.js in Optimization > JavaScript Optimization. This may be useful but it occupies an HTTP/2 connection slot.
= 0.8.2-beta.rc – 2026-01-09 =
FIXED: Adjusted autoload values used by the plugin, which previously overfilled the wp_options table. Only essential items are now autoloaded.
FIXED: Compatibility issue on some hosting environments where mod_access_compat was not enabled.
IMPROVED: Complete overhaul of the CSS optimization section, specifically delivery methods (On Interaction, DOMContentLoaded Event, and Async).
IMPROVED: Critical CSS delivery method now allows choosing between inline insertion or file-based insertion for overall reduction. This is an optimization improvement, not a precise per-page Critical CSS generator. Accuracy is approximate, but performance gains are significant.
FIXED: Exclude and preload functionality for above-the-fold images corrected for both mobile and desktop versions.
BUGFIX: Purge All now correctly removes all CSS.
BUGFIX: Migration from older plugin versions could break the Font Detector; logic has been fixed.
FIXED: Dependency chain for LCP, TTFB, and Metrics files corrected.

* FIX: Ensure page-cache enable/disable toggles correctly and dependent optimizations respect cache state and configuration dependencies.
* FIX: Fix Redis connection handling and Unix-socket support (on OpenLiteSpeed servers) — avoid attempting connections with an empty host (php_network_getaddresses error), correctly detect and use Unix socket paths, and prevent undefined “host”/”port” errors in the generated object-cache.php.
* FIX: Reduce verbose debug logging and stop spurious DB/JSON errors by adding Action Scheduler table-existence checks.
* FIX: Suppressing noisy BFCache/Image/Font/SysConfig debug output, replacing direct error_log() calls with CacheSys::writeError().
