### Problem to solve
<!-- What problem do we solve? Try to define the who/what/why of the opportunity as a user story. For example, "As a (who), I want (what), so I can (why/value)." -->
As a user that uses the GitLab CLI in a custom script I have written, I now sometimes get an output like
```
What's new in glab v1.105.0
Run: glab whatsnew
```
in my scripts output when executing `glab repo clone`. This is unnecessary noise that I don't want in the output of my script. However, I can not just suppress the output of the command because that would also hide actually useful information.
### Proposal
<!-- How are we going to solve the problem? -->
I would like to have a config option and/or an environment variable that I can set to disable these "What's new" reminders.
### Further details
<!-- Include examples, use cases, benefits, goals, or any other details that will help us understand the problem better. -->
