Not attempting to give misinformation but even large updates using the same rom it has been suggested on this very forum to at the very least wipe the cache partition and others recommend doing a factory reset to prevent bugs.
I've been an Android user since 2009 and while I occasionally will do a factory reset I seldom do it when flashing an upgrade to the OS. Even back in the crazy days when I flashed nightlies for a period of 2 years I seldom did a factory reset. Only when I changed to a different person's build.
If I encounter any problems I will do a factory reset but not until then. It doesn't make sense to be so disruptive unless it's necessary.
