Servebolt Optimizer v3.0.0 includes a total rebuild of the plugin, support for Accelerated Domains, improved cache purging and more.
Version 3.0.0 is a major rewrite of Servebolt Optimizer and we highly recommend you testing this update on staging before you update in on production.
- Rewritten codebase – The whole plugin code base is rewritten. This was done since the previous structure did not allow for automated testing (using PHP Unit) nor was it up to par with modern PHP. To achieve this the code base was rewritten to use PSR-4 autoloading as well as making the existing code testable. The code standard was also changed to PSR-1. The new required PHP version is 7.3 or higher.
- PHP Unit tests – PHP Unit tests have been added as an attempt to prevent errors, speed up the development process, and ensure better overall code quality.
- Accelerated Domains by Servebolt – The plugin has support for activating Accelerated Domains by Servebolt. The addition of this feature affects the cache purge system which previously only worked with Cloudflare, but now also supports Accelerated Domains and its cache feature. This can be controlled by selecting the cache provider in the cache purge settings.
- CLI-commands – JSON-support – The CLI-commands now has an optional JSON return format. This can be done by adding
–format=jsonto the command call. Note that the Full Page Cache-related commands do not have this support yet, but all other commands has.
- CLI-commands – Cloudflare CLI commands removed – Since the cache purge feature now works with both Cloudflare and Accelerated Domains then the feature is no longer only specific to Cloudflare. This lead to most of the Cloudflare-related commands being migrated to the
wp servebolt cache settings-namespace. The only remaining Cloudflare-related CLI command is
wp servebolt cf setupwhich works like before, but now also has JSON return format supported as mentioned earlier.
- Improved cache purging – The cache purge feature is improved and expanded. See below.
- Cache purging of old URLs – Whenever a post/term URL is changed then the system will purge the old URL. This is useful since otherwise you would possibly get conflicting URLs and/or duplicated content.
- WooCommerce compatibility – The cache will now be purged for a WooCommerce product whenever the stock amount/status changes, like during a checkout. This is necessary to keep the stock up to date for the visitors/customers, especially on high traffic sites. Cache purging will now also purge all URLs of a variable WooCommerce product.
- Improved exception handling – Whenever there is an error during a cache purge request the system now has an improved handling of exceptions being thrown.
- WP Rocket compatibility – WP Rocket’s cache feature was previously in conflict with Servebolt’s own cache feature. This should now be solved since WP Rocket’s cache feature is disabled as long as the Full Page Cache-feature is active in Servebolt Optimizer. This allow users to still use the other features of WP Rocket without conflicts.
- Improved queue handling when purging cache – In the cache purge feature there is an option to use a queue that will send the list URLs (that should be cached) in delayed chunks instead of sending them all immediately. These requests would typically originate from a post update, or whenever someone does a WooCommerce checkout and the product stock changes. This update improves the handling where the amount of URLs previously would have exceeded the allowed amount according to Cloudflare.
- Third party cache purge functions – Third party developers can now call publicly available cache purge functions. This allows for purging by post, term, URL or purge all.
- Single site plugin activation constraint – The plugin can now only be activated site-wide when used in a multisite network.
- Cloudflare Image Resizing removed from the GUI – The beta-feature “Cloudflare Image Resizing” has now been removed due to it not being tested properly. It is still available through the CLI, but not in the GUI.
- Removed network cache purge action – The feature to purge all cache for all sites in a multisite-network was removed due to lack of time to integrate this with Accelerated Domains and the improved queue system.
- Removed the cache purge queue GUI – The queue GUI (list) in the cache purge settings was removed due to lack of time to integrate this with Accelerated Domains and the improved queue system.
- Cache purge links in post/term list – It is now possible to trigger cache purge actions from the row actions of posts and terms in WP Admin.
- Added purge actions for terms in the WordPress Admin bar – When viewing a term – either in WP Admin or front-end – you can now purge the cache via the Admin bar.
- Added custom HTTP User Agent string to API requests – The outgoing requests from the plugin now uses a custom user agent string that will allow for easier identification of requests originating from the plugin.
- Log viewer GUI update – The log viewer GUI has gotten overhauled with better styling.
- Fixed bug – The form containing the cache purge configuration had autocompletion on. This lead to problems with information wrongfully being submitted. This is now fixed.
- Fixed bug – Host determination function failed when in CLI context. The function
isHostedAtServeboltreturned false regardless of hosting environment when running in CLI-context. This is fixed in this version.
- Fixed bug – Cache headers absent in archives. When using Full page caching and setting the post type to
allthen the archives got not cache headers. This version fixes that.
