= 5.0.0 =
Release date June 14th, 2022

We hope today is a lucky day because SPIO 5 is super cool, excellent, and faster. Now, bug-free! Just kidding :-) read on for the changelog and be kind to us in reporting issues. The dev team will be eternally grateful!
* New: this is a major rewrite of the plugin, where all the processing engine has been completely changed, as well as other major parts of the plugin;
* New: the optimization information is moved to custom tables in the database in order to avoid the situation when re-optimization occurs because ShortPixel optimization data was wiped;
* New: the whole bulk processing has been reworked and streamlined into a very nice 4 steps process, with more details and clarity about what is going to be processed;
* New: the JavaScript processor that is in charge of processing everything that needs to be optimized has been completely rewritten, adding more clarity and details;
* New: added WP-CLI support for most of the operations that can be performed with the plugin; please check the knowledge base for more details;
* New: due to the new bulk and JS processor, WebP and/or AVIF files can be generated without the need to re-optimize the whole Media Library;
* New: added more features for Custom Media, such as Cloudflare integration, displaying the internal ID for easier tracking, checks for permissions when adding new folders, and other smaller fixes;
* New: the settings were reorganized and refreshed, a Tools tab was added and tooltips are now available for an easier understanding of the functionalities;
* New: Breaking Change! regex exclusions are now moved to their own type `regex-name` and `regex-path`; if you are using regex exclusions please check them in detail and adjust as necessary;
* New: added the possibility for double AVIF extension that works in a similar manner to the double WebP extension;
* Tweak: removed `Process in the front-end` option due to performance issues; the same effect can now be achieved with WP-CLI commands;
* Tweak: Breaking Change! due to the code changes, some of the filters in version 4 are now deprecated; please check again your integrations if you used a filter in version 4;
* Tweak: removed the integration with Cloudflare Global API Key for security reasons, please use the Cloudflare Token instead;
* Fix: the image size is now updated correctly in the database (following the change in WordPress 6.0);
* Fix: in some cases, when running out of credits, the PDF upload wasn't possible;
* Fix: the optimized/unoptimized filter in Media Library works correctly now;
* Fix: a confirmation message shows up again when saving settings;
* Language: pretty much all strings were either added, updated, fuzzed, or obsoleted, therefore we didn't lose time in counting them; we hope you will understand.
