Aimy Speed Optimization v13.0 includes a Czech translation, an updated version of [be]Lazy.js and handles cached images.
Czech Translation
A Czech translation has been contributed by Aqui - thanks!
Handling of Cached Images
Aimy Speed Optimization now handles cached images (those stored beneath the
/cache/ directory within a Joomla! website’s root directory) like the ones
stored in the /images/ directory.
As a result, cached images can now be lazy-loaded and loaded deferred.
Updated [be]Lazy.js
The [be]Lazy JavaScript library
(blazy.js) used by Aimy Speed Optimization to lazy-load images has been
updated to the current version (v1.8.2).
Workaround for Unsupported Module
A workaround has been added to handle the unsupported module “Horizontal scrolling slideshow joomla module” by Gopiplus: the JavaScript code of the module will be ignored when the “Eliminate Render Blocking” option of Aimy Speed Optimization is enabled.
Browser-Caching: Extended Set of MIME-Types
The MIME-Type “font/woff2” has been added to the set of resources that
should be cached by a browser if the “Enable Browser-Caching” option is
enabled.
Check for Mbstring PHP Extension
A check has been added to assure the “mbstring” PHP extension is available. The “HTML5-PHP” library used by Aimy Speed Optimization requries the library to be available (as well as the “Dom” extension). The user manual has been updated accordingly.
