Advice for Update cms

Hello,
I am using cms version 2.3.5
with xibo client r252-5. Everything works as I want.
do I have to update the cms version, or can I still work with this function, I’m afraid to update and encounter a potential problem thanks

Hello,
Ultimately it is your decision but by not upgrading you wont benefit from bug fixes and security patches in later releases.

thank you for your reply
