There have been two hotfix releases after the initial 17.1. One yesterday, one today, hence the new update installs. That should be it for now unless someone discovers another semi-severe issue.
Better preservation of settings during updates will be looked into sometime this year. Up until now everything VR related (including vorpX) was so much in flux that settings were overwritten on purpose.
If you have games that you invested a lot of time in settings wise, you can make backups of your settings in the config app. Either in the cloud if you want to share them or locally as settings files.
