Change log Retention time

Hi, is there any time limit set for change log retention? (something similar is already available for process log). 

 Or do I need to manually clear the change log every time? I know there is a business process called "Clear Change Log", which I could use to automate this.  I wanted to check if there is already an out-of-the-box feature available for this before beginning development.

I also noticed that even when a particular record is deleted, its change log remains in Creatio. I understand this is intended behavior to track changes, which is good, but we don’t want it to stay forever.

Thanks
