Default is 'relative'.\n\t\t\t\t\t\t This improves compatibility with CDNs, 3rd party CSS optimizers\/minimizers, and some \n\t\t\t\t\t\t polyfills.\n\t\t\t\t\t\t- Implemented QueryMonitor timing\n\t\t\t\t\t\t- Added \"Core Framework\" to incompatibilities if installed together with Oxygen Builder\n2024-03-15\t3.4.2\t\tFixes:\n\t\t\t\t\t\t- Fixed PHP warning in admin_init() line 818: $_REQUEST['page'] might not be defined \n\t\t\t\t\t\t when using Bricks.\n2024-03-04\t3.4.1\t\tChanges:\n\t\t\t\t\t\t- Builder fonts in Gutenberg: Call of Oxygen function ct_get_global_settings embedded\n\t\t\t\t\t\t in call_user_func() to avoid being marked as unknown in Bricks setups.\n\t\t\t\t\t\tFixes:\n\t\t\t\t\t\t- Fixed PHP warning in admin_init(): Variable $builder_fonts_to_gutenberg definition \n\t\t\t\t\t\t was inside of Oxygen block, hence undefined in Bricks block.\n2024-02-25\t3.4.0\t\tReorganization of code base.\n\t\t\t\t\t\tNew Features:\n\t\t\t\t\t\t- Support for assigning fonts in Gutenberg. \n\t\t\t\t\t\t Can be disabled by setting $gutenberg_font_family_select = false;\n\t\t\t\t\t\t- Oxygen Builder: Hide \"Top 20\" Google Fonts if Google Fonts are disabled.\n\t\t\t\t\t\t- Added filter for excluding ma-customfonts.css from FlyingPress CSS minimizer\n\t\t\t\t\t\t which causes issues with already minimized CSS containing @font-face rules.\n\t\t\t\t\t\tChanges:\n\t\t\t\t\t\t- Changed CSS file name from ma_customfonts.css to ma-customfonts.css\n\t\t\t\t\t\t- Changed test page slug from ma_customfonts to ma-customfonts\n\t\t\t\t\t\t- Removed setting $recursive for font file scan. Always scan recursive.\n\t\t\t\t\t\t- Added compatibility check for \"Oxy Font Manager\"\n\t\t\t\t\t\t- Oxygen Builder font lists now show \"Custom\" badge for injected fonts\n\t\t\t\t\t\t- Custom Fonts Test now loads CSS using URL parameter ver= to assure proper refresh.\n\t\t\t\t\t\t- Setting $fonts_in_gutenberg changed to $builder_fonts_in_gutenberg (Bricks, Oxygen)\n\t\t\t\t\t\t- Setting renamed: \n\t\t\t\t\t\t $cssoutput to $css_output, $cssminimize to $css_minimize, $fontdisplay to $font_display\n\t\t\t\t\t\t- $timing now allows levels 0\/false (off), 1\/true (basic), 2 (extended)\n\t\t\t\t\t\t- $timing now also calculates memory usage. Please note that memory usage won't simply \n\t\t\t\t\t\t be cummulated. Methods use memory temporarily but also free memory after use.\n2022-10-17\t3.3.1\t\tChanges:\n\t\t\t\t\t\t- Migrated JavaScript from jQuery to vanilla JS (ES6) to eliminate jQuery dependency.\n\t\t\t\t\t\t- Modernized initialization to avoid errors with WPCodeBox:\n\t\t\t\t\t\t Replaced @ error control operator with ?? null coalescing operator\n\t\t\t\t\t\t (Thanks to Alexander van Aken for reporting)\n2022-09-26\t3.3.0\t\tNew Features:\n\t\t\t\t\t\t- Custom Fonts are now also available in Bricks Builder.

Only custom fonts are now assigned.\n\t\t\t\t\t\t (Thanks to Kamil Alhaijali for reporting) \n2022-09-19\t3.2.7\t\tCompatibility Fix:\n\t\t\t\t\t\t- In Oxygen 4.0.4, Pro Menu calls ECF_Plugin::get_font_families() as Ajax call. \n\t\t\t\t\t\t For performance reasons, MA Custom Fonts doesn't get initialized for Ajax calls and \n\t\t\t\t\t\t doesn't have the base font directory set, which causes an error. We now just return \n\t\t\t\t\t\t an empty custom fonts list to prevent this error. That doesn't impact the Pro Menu \n\t\t\t\t\t\t functionality. \n\t\t\t\t\t\t (Many thanks to Kevin Pudlo from the Oxygen development team for reporting, support \n\t\t\t\t\t\t and testing concerning

also WOFF files to support \n\t\t\t\t\t\t ancient browsers before 2016 like Internet Explorer, or Safari on older Apple devices.\n\t\t\t\t\t\t The new default setting is to NOT provide old style WOFF files for ancient browsers.\n\t\t\t\t\t\t Set this option to true if you still need to support old browsers before 2016.\n\t\t\t\t\t\t (Many thanks to Sunny Trochaniak and Yan Kiara for reporting issues and supporting \n\t\t\t\t\t\t investigations with unexpected WOFF loading when using symbols\/emoji)\n\t\t\t\t\t\t- Added display of timing details at end of page Appearance > MA Custom

https:\/\/developer.mozilla.org\/en-US\/docs\/Web\/CSS\/@font-face\/font-weight#values\n\t\t\t\t\t\t (Thanks to Paul Batey for reporting)\n\t\t\t\t\t\t- Completely re-built custom font test screen (WP
