The same files are included between patches, so if you got version 0.43.0 you could patch straight to 0.43.6 without any issues, no need to get 0.43.5, ect. If you are updating between full releases, you will need to get the newer base version of the game first and then copy your save folder over to there. So you can't use a patch to go from version 0.42.3 to 0.43.0, for example.
