To factory reset, or not, after OS update.

[rp115640]

Is it neccessary to perform a factory reset after updating the Android OS?
I've been seeing a lot of mix comments about this in other forums. Some claims that it is a must to perform a factory reset after the update. Some argue that it is only neccessary after a major update, eg. updating from A9 to A10. Then there are others who suggest that only clearing the cache is suffice. But there are also those who says that these are only required should the user experience problems after the update.
Well, which is the truth? Thanks in advance.

The wipe cache partition option is not available in recovery mode ,so reset is the only way sadly. Otherwise wipe cache partition is enough after update.

Yeah i don't know why it's not in recovery mode? And it's very useful in major updates. I also don't want to factory reset
