Changelog

Bug fixes

• [LOW] WEBP and responsive images were not loaded over CDN.

Miscellaneous changes

• Added support for resizing WEBP images to create responsive images
• Background images that are LCP with responsive images generated can now be appropriately preloaded with high priority

Release notes

What's new

This release introduces a major new feature, Responsive Images, to further reduce LCP, especially on mobile.

This works for both HTML images and for background images in CSS files. For HTML images, a srcset attribute is added to the element containing the different sized images to load for different media sizes. For CSS images, the plugin will add additional CSS wrapped in media queries to load the different sized images at different viewport sizes.

You must optimize the images first to generate the different sizes. If images were optimized before, you may want to temporarily disable the 'Ignore optimized images' setting to facilitate a re-optimization.

Other minor improvement and bug fixes, please see CHANGELOG.

Release notes

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.

Changelog

New features

• Add Custom CSS feature to reduce CLS
• Add HTML sections setting to Reduce DOM feature
• Add feature to preload LCP images with high fetch priority

Release notes

What's new

JCH Optimize will delete cache files when they have expired. Sometimes, if you're using another page cache plugin then it's possible that a cached page can be loaded with links to orphaned files, leaving the site without CSS and JavaScript. To mitigate this we recommend setting the cache lifetime in JCH Optimize much higher than your page cache lifetime. However, in this version we've added a setting to disable to deletion of cache files to avoid this altogether. You may just have to watch if you're building up an excess amount of cache. Better still, we recommend using the JCH Optimize Page Cache plugin and keep cache expiry deletion enabled. You'll also benefit from the HTTP Request feature that serves cached pages without calling PHP, significantly reducing initial server response. A few bug fixes since the last stable release is also included. Please see CHANGELOG for details.

Changelog

New features

• Added setting to optionally disable deletion of cached files when expired.

Bug fixes

• [MEDIUM] Imported Google fonts were not being handled properly.
• [MEDIUM] Reduce Unused JavaScript wasn't working properly on some sites.
• [MEDIUM] Some external domains were not being preconnected when Optimize Fonts is enabled.

Miscellaneous changes

• Added support for inline modules.
• Further improvements in compatibility with MightySites.

• Optimize Images tab using modals for improved aesthetics.

Release notes

What's new

Several new enhancements were developed to better optimize sites. Of special note, The Optimize Google Fonts feature was expanded to include all fonts and provision for special handling of other font files ig required. The Reduce Unused JavaScript feature was further enhanced to include modules, but also to exclude modules that are dependent on critical files/script. For most users this change should go smoothly, all the ones we've tested did but a few sites may need to reconfigure this feature to get the best results from this change. Please see CHANGELOG for details.

Changelog

New features

• Added setting to Lazy-load background images defined in the CSS files to the Lazy-Load feature.

What's new

Several bug fixes and improvements. Please see CHANGELOG for details.

Changelog

New features

Bug fixes

• [HIGH] Fixed conflict with Cache Cleaner causing settings not to be saved in component.
• [LOW] CDN feature broke processing same images used multiple times in srcset.
• [LOW] Optimize Image didn't work with file paths that include spaces.
• [MEDIUM] Fix resizing images not working with Manual Option on some servers.
• [MEDIUM] Google fonts that were imported in CSS files weren't being optimized and loaded.

Release notes

What's new

We've made some more improvements to more aggressively delete expired cache but without deleting any files whose URLs are still cached on any pages to prevent pages being orphaned without CSS/JS files that were expired and deleted. Testing has proved this to be effective in stabilizing cache growth on even very volatile sites. If you've been affected by this issue please update.

Before introducing our own page cache plugin in 7.2.0 we had a Page Cache Integration cache feature that allowed users to integrate the page cache they're using with the JCH Optimize and could disable/enable page caching when the component is put in Development/Production mode respectively. Since we now have our own page cache plugin this feature was removed, and we recommend using the JCH Optimize Page Cache plugin for best compatibility, especially in light of the likely issue of having CSS/js files that have been expired and deleted still being cached on the page.

You can still use a different cache plugin if you prefer. If you do then you should set the lifetime setting in your page cache application to less than the lifetime configured on the General tab in the JCH Optimize Options page. We recommend JCH Optimize lifetime being at least twice that of page cache. Doing this will mitigate the likelihood of this happening, but we can't guarantee it won't happen unless you use our page cache plugin.

Changelog

Removed features

• Removed setting to integrate third party page cache plugin with the component

Changes

• Further improvement in cache management to reduce cache build up on some sites

Bug fixes

• [MEDIUM] Fixed preloading duplicated google fonts.

Release notes

What's new

The previous release contained some changes in the codes we used in the .htaccess files to leverage browser caching, and it was causing 500 Internal Server errors on sites running older versions of Apache. Some statements contained a space at the end which worked ok with all our dev servers and the sites we tested on, so we didn't detect an issue before release. This release corrects that, please update if you were affected by this issue.

Changelog

• Fix issue with .htaccess codes causing 500 errors on older versions of Apache

Release notes

What's new

As of this release, JCH Optimize no longer uses the FOF framework developed by Akeeba Ltd since development of that library has been discontinued. We have opted though not to automatically uninstall FOF as was previously planned and announced, but will leave this to the user to do instead. This is because some other third party software that have not properly registered their dependence on FOF may be installed on the website. It is however recommended to uninstall the library if you are sure you are not using any other extension that is dependent on FOF.

This version uses a different caching system than Joomla! in order to take advantages of some features that are currently absent, so it may show that there are 0 cache files for com_jchoptimize when you visit the Cache Manager in Joomla!. The files can still be deleted but if you want to see the amount of cache generated you'll need to go to the Dashboard in JCH Optimize.

There is a new page cache plugin included in the package with a new page in Administration and tab in the Settings related to the features of this page cache. Most prominently the ability to ship static caches of the page without calling PHP that significantly improves initial render time. Additionally, there is a new feature to assist with the issue raised on PageSpeed regarding 'Remove Unused Javascript' that if configured properly, can provide improved page performance. The descriptions in the settings are information, but I will be spending the next few days to update the documentation to cover these new features in more detail. In the meantime if you need assistance feel free to contact us.

Changelog

Release notes

What's new

Please note that JCH Optimize uses the FOF4 library developed by Akeeba.com. They have announced that they will discontinue development of this library and in fact have Joomla 4 native version of all their extensions. Consequently, we are actively developing a version of JCH Optimize that doesn't use FOF which is planned for 7.2.0. In the meantime please do not uninstall FOF4 if you're using JCH Optimize, it will be uninstalled when you install 7.2.0 or if you uninstall JCH Optimize if you're not using any other extensions that uses FOF4. This version provides support for Joomla 4.1.* and allows you to install the package which includes FOF4 on your site.

Please see CHANGELOG for further details of other changes.

What's new

This is a major upgrade from the last version. This version also now supports Joomla! 4. The settings are normally accessed in the plugin under Plugin Manager but now JCH Optimize is a package containing an administrator component, module (in the pro version) and plugin, so the settings are moved to the component. You'll now also find an entry for JCH Optimize in the component's menu in the administrator section.

This installation is now actually a new entry in Joomla!'s extension database so the settings will be imported from the previous installation and the old installation deleted. Please note, it's not possible to downgrade to previous versions, you'll need to uninstall this version first otherwise you'll end up with two installations of JCH Optimize on your site.
