As long as you stick with the releases from the same uploader you should be fine with any future updates, though backup the save folder before updating just in case.I don't remember dogs, were they added after 0.95? Also is this worth playing right now or are updates still pending?
Mr Technician usually tests whether or not saves work in new patches for the release they share.
brt345678 doesn't do any save compatibility testing, but results should be identical to those of Mr Technician
Again, this is ONLY if you stick to updates from the same uploader. Do NOT switch or you will need to start fresh.
The project is complete so any future updates should just be bugfixes or other maintenance.
Also, for all releases, saves from before v1.00 are not compatible (Steam is an exception if the saves are also from the Steam pre-1.00 versions)
