Autoptimize

3.1.11

• code quality improvements see the GitHub commit log.
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.10

• improvement: with “don’t aggregate but defer” and “also defer inline JS” on, also defer JS that had the async flag to avoid the (previously) asynced JS from executing before the inline JS has ran.
• improvement: show option to disable the default on “compatibility logic”.
• fix for regression in 3.1.9 which caused JetPack Image optimization not working even if image optimization was off in AO.
• API: some extra hooks in critical CSS to enable others (and AOPro) to act on changes in critical CSS rules
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.9

• improvement: activate JS, CSS & HTML optimization upon plugin activation (hat tip to Adam Silverstein (developer relations engineer at Google))
• improvement: also defer asynced JS (to ensure execution order remains intact; asynced JS should not execute before deferred inline JS which it might depend upon)
• improvement: exclude images from being lazyloaded if they have fetchpriority attribute set to high (as done by WordPress core since 6.3)
• bugfix: disable spellcheck on CSS textarea’s (above the fold CSS/ critical CSS) which in some cases caused browser issues
• add tab to explain Autoptimize Pro.
• confirmed working with WordPress 6.4 (beta 3)
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.8.1

• urgent fix for PHP error, sorry about that!

3.1.8

• Images: improve optmization logic for background images
• Critical CSS: don’t trigger custom_post rule if not is_singular + adding debug logging for rule selection
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.7

• security: improve validation (import) and sanitization (output) of critical CSS rules, to fix a medium severity Admin+ Stored Cross-Site Scripting vulnerability as reported by WP Scan Security.

3.1.6

• CSS: removing trailing slashes in <link tags for more W3 HTML validation love
• Extra: also dequeue WooCommerce block CSS if “remove WordPress block CSS” option is active
• imgopt: also act on non-aggregated inline CSS
• imgopt: added logic to warn users if Shortpixel can’t reach their site
• backend: AO toolbar JS/ CSS is finally minified as well.
• explicitly disable optimization of login pages
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.5

• improvements to JSMin by Robert Ehrenleitner (big thanks Robert!).
• do not consider jquery.js as minified any more (WordPress now uses jquery.min.js by default and jquery.js is the unminified version).
• fix for “undefined array key” PHP errors in autoptimizeCriticalCSSCron.php
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.4

• Improvement: when all CSS is inlined, try doing so after SEO meta-tags (just before ld+json script tag which most SEO plugins add as last item on their list).
• Img opt: also optimize images set in data-background and data-retina attributes (+ filter to easily add other attributes)
• CSS opt: filter to enable AO to skip minification of calc formulas in CSS (as the CSS minifier on rare occasions breaks those)
• Multiple other filters added
• Some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.3

• Multiple fixes for metabox LCP image preloads (thanks Kishorchand for notifying & providing a staging environment to debug on).
• Fix in revslider compatibility (hat tip Waqar Ahmed for reporting & helping out ).
• No image optimization or criticalcss attempts on localhost installations any more + notification of that fact if localhost detected.
• Some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.2

• Google Fonts: some more removal logic
• fix for 404 fallback bug (hat tip to Asif for finding & reporting)
• Some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.1.1

• Quick workaround for an autoload conflict with JetFormBuilder (and maybe other Crocoblock plugins?) that causes a critical error on the AO settings page.

3.1.1

• images: when optimizing images and lazyloading is on, then by default do not set an LQIP (low quality image placeholder) any more (reason: it might look nice but it comes with a small-ish perf. penalty). This can be re-enabled by returning true to the autoptimize_filter_imgopt_lazyload_dolqip filter.
• security: further improvements to critical CSS settings page (again with the great assistance of WPScan Security).
• some other minor changes/ improvements/ filters, see the GitHub commit log.

3.1.0

• new HTML sub-option: “minify inline CSS/ JS” (off by default).
• new Misc option: permanently allow the “do not run compatibility logic” flag to be removed (which was set for users upgrading from AO 2.9.* to AO 3.0.* as the assumption was things were working anyway).
• security: improvements to the critical CSS settings page to fix authenticated cross site scripting issues as reported by WPScan Security.
• bugfix: “defer inline JS” of very large chunks of inline JS could cause server errors (PCRE crash actually) so not deferring if string is more then 200000 characters (filter available).
• some other minor changes/ improvements/ hooks, see the GitHub commit log

3.0.4

• fix for “undefined array key ao_post_preload” on post/ page edit screens
• fix for image optimization altering inline JS that contains an <img tag if lazyload is not active
• improvements to exit survey
• confirmed working with WordPress 6.0

3.0.3

• fix for images being preloaded without this being configured when lazyload is on and per page/post settings are off.
• ensure critical CSS schedule is always known.
• when deferring non-aggregated JS, make the optimatization exclusions take the full script-tag into account instead of just the src URL.

3.0.2

• rollback automatic “minify inline CSS/ JS” which broke more then expected, this will come back as a separate default off option later and can now be enabled with a simple filter: add_filter( 'autoptimize_html_minify_inline_js_css', '__return_true'); .
• fix for “Call to undefined method autoptimizeOptionWrapper::delete_option()” in autoptimizeVersionUpdatesHandler.php

3.0.1

• fix for minification of inline script with type text/template breaking the template (e.g. ninja forms), hat tip to @bobsled.
• fix for regression in import of CSS-files where e.g. fontawesome CSS was broken due to being escaped again with help of @bobsled, thanks man!

3.0.0

• fundamental change for new installations: by default Autoptimize will not aggregate JS/ CSS any more (HTTP/2 is ubiquitous and there are other advantages to not aggregating esp. re. inline JS/ CSS and dependancies)
• new: no API needed any more to create manual critical CSS rules.
• new: “Remove WordPress blocks CSS” option on the “Extra” tab to remove block- and global styles (and SVG).
• new: compatibility logic for “edit with elementor”, “revolution slider”, for non-aggregated inline JS requiring jQuery even if not excluded (= auto-exclude of jQuery) and JS-heavy WordPress blocks (Gutenberg)
• new: configure an image to be preloaded on a per page/ post basis for better LCP.
• improvement: defer inline now also allowed if inline JS contains nonce or post_id.
• improvement: settings export/ import on critical CSS tab now takes into account all Autoptimize settings, not just the critical CSS ones.
• technical improvement: all criticalCSS classes were refactored, removing use of global variables.
• technical improvement: automated unit tests on Travis-CI for PHP versions 7.2 to 8.1.
• fix: stop Divi from clearing Autoptimize’s cache which is pretty counter-productive.
• misc smaller fixes/ improvements, see the GitHub commit log
