 * Hi Dan,
 * The Cookiebot plugin uses an older version of the php-di dependency in order 
   to support older versions of PHP.
 * Can you please elaborate on which WordPress functions you’ve been having issues
   with? Usually a deprecation message won’t cause any problems.
 * Kind Regards,
 * Team AppSaloon

 * I am sorry for the late reply. I will appreciate if you can provide php 8 compatibility
   as many other developers have done and are doing. If someone is using a very 
   old php version it is their problem, not yours.

 * Hi Dan14
 * I just got word from Cookiebot that the issue should be resolved in the future
   Cookiebot release version 3.11.0
 * I hope this also solves your problem.
 * Kind regards

 * Hi Dan,
 * This issue was resolved with release 3.11.0 on 23 Jul, 2021.
    [https://github.com/CybotAS/CookiebotWP/releases/tag/v.3.11.0](https://github.com/CybotAS/CookiebotWP/releases/tag/v.3.11.0)
 * We removed the PHP-DI dependency because we had to use an outdated version to
   maintain compatibility with older PHP versions. This caused some issues with 
   PHP 8 instead. So we replaced the entire thing with a custom lightweight class
   to handle dependency injection across the plugin code.
 * With the removal of PHP-DI, the Cookiebot plugin no longer contains any Composer
   dependencies.
 * Kind regards,
 * Team AppSaloon
