The versions with caveats should all be enumerated in https://github.com/apache/cassandra/blob/cassandra-3.0/NEWS.txt
The biggest caveat was 3.0.14 (which had the fix for cassandra-13004), which you're already on. Personally, I'd qualify exactly one upgrade, and rather than doing 3 different upgrades, just do exactly one and spend 3 times as long proving it's safe in non-production.
