Which Files Need to be manually overwritten between 2.9.1 and 2.9.2 to upgrade?

I am running 2.9.1 and have a few themes, plug-ins, etc installed. I would rather not mess any of these things up by overwriting the ENTIRE 2.9.1 set of folders with the 2.9.2.

Can anyone tell me which are the files that changed between these two versions so I can only copy those? I read in another thread that there are 10 of these.

Thanks in advance!
