My experience is mostly that you either upgrade because it has a feature you need (then you try it out fast), if it has some performance or other nice thing (then you go for the .1) or you don't really care then you upgrade when your current version goes EOL or if you upgrade your underlying server OS (if we assume something like Ubuntu LTS, and they'd go with 14 instead of 12 or something).

When a new version reaches RDS we start planning for the upgrade. We like the new features so we try to stay as current as we can.
