= 2.6.8 – 09.09.2026 =
* Added new Inline Excluded Stylesheets advanced option to automatically inline stylesheets excluded from Remove Unused CSS.
* Added new Safe Mode option to disable all Perfmatters performance optimizations sitewide without impacting security-related options or code snippets.
* Added new Load in Block Editor option for frontend CSS code snippets so those styles can also appear in the WordPress block editor canvas.
* Added new perfmatters_inline_scripts filter which allows you to inline specific local JavaScript files.
* Improved stylesheet inlining via the new perfmatters_inline_stylesheets filter (perfmatters_rucss_inline_stylesheets still supported), which can now run independently of Remove Unused CSS while still deferring to RUCSS for non-excluded stylesheets.
* Made some adjustments to code snippets UI visibility script.
* Moved Instant Page, Preconnect, and DNS Prefetch into the main Perfmatters queue so they respect the same request-level disable checks as other front-end optimizations.
* Removed redundant admin and ?perfmattersoff checks from FastClick output, which is already gated by the main Perfmatters queue.
