"Huihun yo"? Um, what?
TaUTwo, not officially. Eccma said this in the announcement for 0.7.2.0:
**TON OF CORE CHANGE. REQUIRE A CLEARN INSTALL**
For safety's sake:
1: Download and unpack the new version to a new folder
2: Load the new version once so that it generates all the files it will need
3: Open the previous version's game.ini and copy the [ACH] section into GameLona.ini just about the [Keyboard] settings
4: Save and exit
It's not recommended to carry saves over. but you can try that if you want by copying over anything that starts with the word "Save" in the root folder - SaveAuto.rvdata2, Save01.rvdata2 and so on.
Or you could not bother and wait for 0.7.3.0 as the man himself said:
I kid you not. This is taken directly from the announcement post.
