I'm waiting a couple of months, the last two upgrades broke certain things on my dev environment, it killed maven and I had to switch to homebrew's maven and one of the other upgrades did something strange to Java which meant I had to spend time getting JDK to work properly again - both times were during busy times when time-wise I couldn't really afford to spend time on those kind of things. If you don't have any giant projects that will be affected if your dev environment stops working, go for it!
