v5.2.10Latest
August 11, 2026414.3 KBScanned
Other
  • Note: this release detects stylesheets which were skipped before, so optionally run Save & Optimize once after updating to add them to your cache. Nothing breaks if you don't.
  • couldn't match the hyphen separating the subset from the font-weight (e.g., source-sans-pro-normal-latin-400.woff2), so no rule ever matched. The subset is now matched against the @font-face rule's
  • unicode-range, and only falls back to the filename for rules which don't define one.
Fixed
  • Optimize Local/External Stylesheets skipped any link element written over multiple lines (or with a line break inside its href attribute), while browsers load those just fine. The pattern used to find them couldn't match line breaks, but could run past the > which ends an element. Both are fixed, and line breaks are now stripped from the URL before it's requested, just like browsers do.
  • @import statements spread over multiple lines weren't detected. CSS allows whitespace (incl. line breaks) after @import and inside url(), and a backslash followed by a line break is a line continuation inside a string, but none of those were matched. A raw line break inside the URL is still ignored, because that's an unterminated string, which browsers don't load either.
  • Smart Optimize (Unused Fonts) could return a blank page when an inline @import statement was fully unloaded. The pattern used to remove that statement removed everything between the first @import and the last occurrence of the stylesheet's URL, and exceeded PCRE's runtime limits on documents larger than ~100KB, in which case the entire document was replaced with nothing (accompanied by a 'preg_replace_callback(): Passing null to parameter #3 ($subject)' deprecation notice). Matching is now confined to a single @import statement, and a failed search/replace leaves the document untouched.
  • Smart Optimize (Unused Fonts) didn't remove any @font-face rules from stylesheets whose fonts are split into subsets. The subset was matched against the font file's URL using a pattern which
  • Smart Optimize (Unused Fonts) now removes a stylesheet's link element from the HTML entirely when all of its @font-face rules are unloaded, instead of leaving behind a request for an empty stylesheet. Generated stylesheets always start with a header comment, which meant they were never detected as empty. This also fixes the deregistration of fully unloaded Async Stylesheets.
  • an unused Material Icons stylesheet wasn't removed from the HTML. Its cached URL was looked up in the wrong list, so it was never recognized, and clearing the link element's href attribute left behind a request for the page itself. Its link element is now removed entirely.
Improved
  • the classes which collect @import statements (and the one which adds the Material Icons subset) registered their filters once per instance, while they're constructed on every processing run. Because nothing ever removed those filters, they stacked up within a single request, which meant the same @import could be optimized several times over, and the Material Icons subset could be added to the subset list more than once.
v5.2.9
August 4, 2026408.0 KBScanned
Fixed
  • with Magic Fallbacks enabled, the first click on a Replace checkbox checked all corresponding "Don't Load" checkboxes, but left the Replace checkbox itself unchecked.
  • with Magic Fallbacks enabled, a Replace checkbox stayed disabled after unchecking the Preload checkbox(es) of the corresponding font family.
  • A corrupted (non-array) Fallback Font Stack option no longer causes a fatal error ('Cannot access offset of type string on string') when opening the Optimize Fonts settings screen.
  • Magic Fallback aliases were incorrectly stored as font families during Save & Optimize, causing a 'could not find a matching fallback font' notice.
  • Magic Fallbacks no longer tries to find a fallback for icon fonts (e.g., Material Icons/Symbols) and no longer shows a 'could not find a matching fallback font' notice for them.
  • Smart Optimize now purges the page cache on taxonomy archives, the homepage and WooCommerce product pages by switching supported caching plugins (LiteSpeed, W3 Total Cache, WP-Optimize, WP Rocket, WP Super Cache) to URL-based purging, so the detection script no longer re-runs on every page load for URLs without a single post-ID.
