Incident - Additional Fields Text Pick List Limit doubt

Incident - Additional Fields Text Pick List Limit doubt

Hello,
 
I have a little doubt about: additional fields for request templates.
 
If i create a text pick list additional field those this one have a certain limit¿?
 
For example we are planning a control of versions from a software and we want to specify in the request on wich version that software incident was. The thing version changes are getting more and more common, and if a pick list text field has a limit of items to be added would be a stopper for implementing this option for us in the future, and before i even try to implement this feature i wanted to know if i would find myself in this situation in the future.
 
Hope i made myself clear enough.
 
Best Regards,
