We use React Router on our project. Looks like 4.0 does break pretty much everything.

My thoughts on the upgrade are pretty much:

- Do we actually need to upgrade? Old react router works fine.

- If we do need to upgrade - how long will it take? If it's just a few hours to shift some code around, maybe it's not that bad. Especially if it's moving to a cleaner more "react" API.

At the end of the day, we could write our own routing class, or another. We'll probably stick with react-router though - but save the upgrade for a day where we've got nothing else to do, or if an engineer has some free time.

Or when you stumble on a show-stopping bug right before a deadline, that is only fixed in supported newer versions.

Is that more or less likely with an older version of something like React Router, or a fairly new release?

This can happen with any release of any open source project. The only surefire way of dealing with it is diving into the source and fixing it yourself.
