Need advice: 1.2.7 to 1.2.13 version upgrade

Hello, everyone.
I need some advice. Is it worth upgrading from 1.2.7 to 1.2.13, when using just SIP. What pitfalls I will possibly run into.
In a while I will visit an installation, where they have asterisk 1.2.7 in production. And there has been no problem with it. So I’m wondering is it worth a risk to upgrade to 1.2.13 and possibly get new problems/bugs or perhaps should I leave it as it is (and possibly one day run into a problem/bug that has been fixed in 1.2.13)?
Thanks in advance for you answers.


Your first port of call is the changelog and it will tell you what has been fixed and as such what bugs.
