No probs here... go for it! 
I think as with software for a recording studio, if you have critical gigs - sometimes it's a good idea to wait for a bit.
That said, I think usually any bugs found after the release stage are relatively minor.
You could always read up on how you downgrade the OS, and keep a USB stick with your current version in your equipment bag - just in case 
I think most people use the newest release without any issues or concerns.
Welcome, Barry!
By all accounts the latest release is stable.
A stable release is a stable release.
If you are really worried, upgrade to 4 at least....
