 * Hi [@slavikcz](https://wordpress.org/support/users/slavikcz/), thanks for the
   message!
 * There is nothing to worry about. This log is not about a critical error. It’s
   just a warning that in future versions of PHP, there will be changes that we 
   will have to take into account.
 * We are aware of this and will address it, before it becomes a real issue, in 
   future releases.
 * If you have other questions, please let us know, we will be happy to help.
 * Best regards,
    Tomek

 * Hi [@tograczyk](https://wordpress.org/support/users/tograczyk/), I hope you’re
   not waiting for PHP 9.0 to be released to fix this.
 * It’s not urgent, but you are professionals so it would be good to do it now 🙂
