What's new

This release is a major upgrade with many new changes, primary of which is compatibility with Joomla 5. Consequently, we no longer support 3.10 since we maintain only one installation package for the different platforms but the code bases were just too different. Minimum PHP version is also now 8.0

Most of the changes are concerned with the Preload tab on the Options page, where we rearrange settings in different features to make it more intuitive and introduced a feature to load Largest Contentful Paint images using the new fetchpriority attribute to improve performance on PageSpeed.

There's also an additional feature on the CSS tab to include CSS declarations to improve Cumulative Layout Shift. When helping other to optimize their site, I often have this need so this makes it easy to insert simple CSS declarations for mobile or desktop to manage shifting while rendering, without worrying about media queries as these will be automatically generated for you.

Additionally, we've rewritten the Optimize Images script to make it more efficient and faster, including some options to modify concurrency or file pack sizes based on your server capabilities to further increase speed or limit output based on server capabilities. See CHANGELOG for additional details.

Developed and tested on up to PHP 8.2.11 and Joomla! 4.4.0|5.0.0
