For executable parts of QGIS, the application and the ~/.qgis2 folder are all there is. There are Python modules (matplotlib, etc.), but those are separate from QGIS, and both versions of QGIS use the same versions of those Python modules.
The readme does say it's best to delete any existing QGIS app before installing another. But nothing about deleting old QGIS plugin junk in .qgis2 (I thought I had something in the readme about this, maybe I did once), it can be tricky for the average user to manage (I have a standing request to move this folder to users' Application Support on OS X). There are preferences in ~/Library/Preferences (org.qgis.something.plist), this is probably where the history of what algorithms were used is stored, but would have nothing to do with what algorithms are currently installed, it's just a record of the past.
