Did php 8.1 under Beanstalk intentionally drop pcntl support?

I use some pcntl functions in a couple php cli apps. I have been using Beanstalk and php for years. I am in production on 8.0 and these functions work fine. I just tried upgrading to php 8.1 but pcntl is not compiled into the php module in Beanstalk. I understand that is necessary to use these functions.

It is easy to verify. This command shows pcntl is enabled on 8.0 but shows nothing in 8.1

php -i | grep pcntl

The specific functions I use are: pcntl_sigprocmask pcntl_sigtimedwait
