Release notes

9.4.4
====================================================================================================
9.4.3
====================================================================================================
[MEDIUM] Fix Cloudflare's whole cache being cleared each time JCH Optimize removed expired files from its cache, with Enable Cloudflare Purge (Pro) on. Only the pages removed from the Page Cache, including pages that used an expired combined file, are cleared at Cloudflare now, sent in batches Cloudflare accepts. Deleting pages on the Page Cache page with none that are still cached no longer clears Cloudflare's whole cache either.
[MEDIUM] Fix pages showing an error page when the Sprite Generator is on and the combined CSS has background images for a sprite.
[MEDIUM] Fix visitors who logged in on the site with Exclude form users on being kept out of the Page Cache after logging out, until the end of the Page Cache's lifetime. The login form is a posted form, and the cookie it set stayed after logout. The User - JCH Optimize User State plugin now removes it when the user logs out, and is included in the free version too.
[LOW] Fix PHP warnings and notices being shown in the responses to the component's admin requests on sites that display PHP errors, which could stop the admin pages working.
[LOW] Fix the Exclude images from sprite and Include additional images in sprite settings failing to list the sprite's images.
[LOW] Fix Add Image Attributes showing an error page on pages with an image button ().
[LOW] Fix Load responsive images (Pro) leaving a broken style attribute on an element above the fold with several background images in its style attribute. All of them are moved to the style element now.
[LOW] Optimize Images (Pro) adds each image to its list of optimized images once. An image optimized again was added again, so the list kept growing.
9.4.2
====================================================================================================
^ Lower the default Concurrency for Recache from 10 to 5, so a recache leaves PHP workers free for visitors. Recache from a web request and the command line used 20 when the setting was never saved.
[HIGH] Fix Redis connections through a Unix socket failing since 9.4.0, so JCH Optimize fell back to filesystem storage. Hosts written as unix:///path, or any absolute path, are now also recognized as sockets.
[HIGH] Fix CSS and JavaScript files outside the site root being readable through encoded slashes (..%2F) in their URLs when files are combined.
[HIGH] Fix tag pages showing an error page after the content for guests when Page Cache is on, and not being cached, since 9.4.0. Tag pages pass their tags as a list, which the Page Cache hit counter didn't accept. It now counts the hit on the first tag, as Joomla does. An error while storing a page in the Page Cache now skips caching it instead of being added to the page.
[MEDIUM] Fix cross-site scripting in the Critical JavaScript Configure Helper, which showed script URLs from the site's pages without escaping them.
[MEDIUM] Fix Save Changes in the Critical JavaScript Configure Helper failing with a server error since 9.4.0, so the selected files weren't saved.
[MEDIUM] Page Cache no longer stores pages left unoptimized for a single request, such as pages loaded in an iframe, requested with jchnooptimize, or where optimization failed, which served the unoptimized page to every visitor.
[MEDIUM] Combining files no longer fetches files from private network addresses, or follows redirects to them.
[MEDIUM] Page Cache's cookies follow the Cookie Path, Cookie Domain and Force HTTPS settings in Global Configuration, and cover the whole site when Cookie Path is empty. The cookie that keeps visitors who posted a form out of the Page Cache only covered the form's folder, and logged-in users could be served captured guest pages in other folders.
[MEDIUM] Settings exports no longer include the Download ID, and the Optimize Images page only includes it for users who can optimize images.
[MEDIUM] The request that starts a Recache can only be used once, and only one Recache runs at a time.
[MEDIUM] After an update, the .htaccess changes and plugin ordering wait for an administrator who can install extensions and reorder plugins, instead of running on a visitor's request or the command line. Caches are still cleared on the next request.
[MEDIUM] Fix the Export, Reset and Import buttons in the dashboard's bulk settings dialog not working.
[MEDIUM] Fix Recache caching no pages when the server can't start PHP from the command line, such as when open_basedir hides the PHP binary. Recaching within a web request logged "Recache failed: Call to a member function get() on null", or stopped with a fatal error after the response was sent that left nothing in the log. Such errors are now logged. The Console - JCH Optimize plugin's recache command and the scheduled task weren't affected.
[MEDIUM] Fix upgrading from the free version to Pro leaving the Console - JCH Optimize, Task - JCH Optimize and User - JCH Optimize User State plugins disabled. An update now enables the plugins it adds, and the plugins already installed keep their state.
[MEDIUM] Fix new installs skipping the post-install tasks, so system plugins weren't put in the order JCH Optimize needs and the Nginx include wasn't filled in.
[MEDIUM] Fix sites collecting several JCH Optimize update sites, including ones left by older versions, which didn't all have the Download ID. After an update, JCH Optimize keeps one update site with the Download ID and removes the rest.
[MEDIUM] Fix Recache failing when the cache storage adapter is unavailable, such as APCu on the command line.
[MEDIUM] Recache from the command line no longer cleans the cache when the selected cache storage can't be reached from the command line, such as APCu, which left cached pages missing from the Page Cache list. It now shows a warning instead.
[MEDIUM] With Optimize CSS Delivery on, Optimize Fonts keeps the @font-face rules used above the fold in the critical CSS. It moved them to a separate stylesheet that loaded after the page, which delayed the fonts.
[MEDIUM] Fix stylesheets listed in Optimize Fonts' "Optimize these files" being removed from the page while Optimize Fonts is off. They are combined as usual.
[LOW] Fix browsers autofilling the administrator login password into the Redis password field.
[LOW] Fix links being injectable into the error message on the Optimize Images page.
[LOW] The Page Cache hit counter ignores scheduled and expired items, and gives the same response whether or not a hit was recorded.
[LOW] Fix a duplicated @import being combined again when Resolve @imports is on.
[LOW] Uninstalling removes all of JCH Optimize's media and language files, the dashboard module's asset and menu assignment, the empty plugin folders it leaves, and its log file.
[LOW] Removing JCH Optimize's section from .htaccess leaves the rest of the file as it was. It left blank lines behind and collapsed every run of blank lines in the file.
[LOW] Fix an "Undefined array key 0" notice when the JCH Optimize Mode Switcher module was installed for the first time.
[LOW] Composer's list of installed packages no longer includes packages that aren't shipped.
9.4.1
====================================================================================================
[HIGH] Fix a fatal error on sites using the Redis or APCu cache storage, caused by classes missing from the bundled Laminas cache library in 9.4.0.

[HIGH] Remove the jchbackend URL parameter that disabled optimization for any visitor.

[MEDIUM] Reject malformed host names in Page Cache and Capture Cache keys, and unsafe characters and path segments in Capture Cache file paths.

====================================================================================================
9.4.3
====================================================================================================
[MEDIUM] Fix Cloudflare's whole cache being cleared each time JCH Optimize removed expired files from its cache, with Enable Cloudflare Purge (Pro) on.

[LOW] Fix Load responsive images (Pro) leaving a broken style attribute on an element above the fold with several background images in its style attribute. All of them are moved to the style element now.
[LOW] Optimize Images (Pro) adds each image to its list of optimized images once. An image optimized again was added again, so the list kept growing.
9.4.2
====================================================================================================
^ Lower the default Concurrency for Recache from 10 to 5, so a recache leaves PHP workers free for visitors. Recache from a web request and the command line used 20 when the setting was never saved.
[HIGH] Fix Redis connections through a Unix socket failing since 9.4.0, so JCH Optimize fell back to filesystem storage. Hosts written as unix:///path, or any absolute path, are now also recognized as sockets.
[HIGH] Fix CSS and JavaScript files outside the site root being readable through encoded slashes (..%2F) in their URLs when files are combined.
[HIGH] Fix tag pages showing an error page after the content for guests when Page Cache is on, and not being cached, since 9.4.0. Tag pages pass their tags as a list, which the Page Cache hit counter didn't accept. It now counts the hit on the first tag, as Joomla does. An error while storing a page in the Page Cache now skips caching it instead of being added to the page.
[MEDIUM] Fix cross-site scripting in the Critical JavaScript Configure Helper, which showed script URLs from the site's pages without escaping them.
[MEDIUM] Fix Save Changes in the Critical JavaScript Configure Helper failing with a server error since 9.4.0, so the selected files weren't saved.
[MEDIUM] Page Cache no longer stores pages left unoptimized for a single request, such as pages loaded in an iframe, requested with jchnooptimize, or where optimization failed, which served the unoptimized page to every visitor.
[MEDIUM] Combining files no longer fetches files from private network addresses, or follows redirects to them.
[MEDIUM] Page Cache's cookies follow the Cookie Path, Cookie Domain and Force HTTPS settings in Global Configuration, and cover the whole site when Cookie Path is empty. The cookie that keeps visitors who posted a form out of the Page Cache only covered the form's folder, and logged-in users could be served captured guest pages in other folders.
[MEDIUM] Settings exports no longer include the Download ID, and the Optimize Images page only includes it for users who can optimize images.
[MEDIUM] The request that starts a Recache can only be used once, and only one Recache runs at a time.
[MEDIUM] After an update, the .htaccess changes and plugin ordering wait for an administrator who can install extensions and reorder plugins, instead of running on a visitor's request or the command line. Caches are still cleared on the next request.
[MEDIUM] Fix the Export, Reset and Import buttons in the dashboard's bulk settings dialog not working.
[MEDIUM] Fix Recache caching no pages when the server can't start PHP from the command line, such as when open_basedir hides the PHP binary. Recaching within a web request logged "Recache failed: Call to a member function get() on null", or stopped with a fatal error after the response was sent that left nothing in the log. Such errors are now logged. The Console - JCH Optimize plugin's recache command and the scheduled task weren't affected.
[MEDIUM] Fix upgrading from the free version to Pro leaving the Console - JCH Optimize, Task - JCH Optimize and User - JCH Optimize User State plugins disabled. An update now enables the plugins it adds, and the plugins already installed keep their state.
[MEDIUM] Fix new installs skipping the post-install tasks, so system plugins weren't put in the order JCH Optimize needs and the Nginx include wasn't filled in.
[MEDIUM] Fix sites collecting several JCH Optimize update sites, including ones left by older versions, which didn't all have the Download ID. After an update, JCH Optimize keeps one update site with the Download ID and removes the rest.
[MEDIUM] Fix Recache failing when the cache storage adapter is unavailable, such as APCu on the command line.
[MEDIUM] Recache from the command line no longer cleans the cache when the selected cache storage can't be reached from the command line, such as APCu, which left cached pages missing from the Page Cache list. It now shows a warning instead.
[MEDIUM] With Optimize CSS Delivery on, Optimize Fonts keeps the @font-face rules used above the fold in the critical CSS. It moved them to a separate stylesheet that loaded after the page, which delayed the fonts.
[MEDIUM] Fix stylesheets listed in Optimize Fonts' "Optimize these files" being removed from the page while Optimize Fonts is off. They are combined as usual.
[LOW] Fix browsers autofilling the administrator login password into the Redis password field.
[LOW] Fix links being injectable into the error message on the Optimize Images page.
[LOW] The Page Cache hit counter ignores scheduled and expired items, and gives the same response whether or not a hit was recorded.
[LOW] Fix a duplicated @import being combined again when Resolve @imports is on.
[LOW] Uninstalling removes all of JCH Optimize's media and language files, the dashboard module's asset and menu assignment, the empty plugin folders it leaves, and its log file.
[LOW] Removing JCH Optimize's section from .htaccess leaves the rest of the file as it was. It left blank lines behind and collapsed every run of blank lines in the file.
[LOW] Fix an "Undefined array key 0" notice when the JCH Optimize Mode Switcher module was installed for the first time.
[LOW] Composer's list of installed packages no longer includes packages that aren't shipped.
9.4.1
====================================================================================================

[HIGH] Remove the jchbackend URL parameter that disabled optimization for any visitor.
