There is no rule to if you need a Factory reset or not; depending on model and settings one may need it each time, other if jumped 3-x version, and for others it works after x dirty upgrades; no one can tell you!I would be surprised if I needed to iterate through each version in order to prevent bugs like this from occurring. Is there any documentation that mentions this? I think I was only a couple of releases behind. Also, everything seems fine after flashing the latest stable with no factory reset.
And yes it is mentioned here in forums many, many, many times. In read-me too I think.
