How do we update RVN Core?

Just wondering how do we update RVN Core to the newest wallet version? Do we just download the newest relative zip folder and copy some files over from the old folder or do I have to re-input my wallet address?

Never done it before, it is telling me a new version of RVN Core is out (4.6.1).

My current RVN Core is says it is 4.3.2.1-25a2dbf41 even though the new downloaded folder has the exact same folder and file name as the old folder?

Sorry if this sounds noobish😱
