I have had some minor problems with some things not working as I expect them to e.g. The Timeline HowTo not working as it should with me. Now I am thinking that it might be because I do not have the latest build installed. One tends to forget that there are minor updates even though the version (2.4) remains the same.

My question: What is best when one upgrades/updates to the latest build? Does one uninstall the previous build and then install the latest one or does one simply install the latest build on top of the previous one?

Ok, silly question [:o]. The installer does not allow you to install with the previous version still installed. One has to uninstall first before installing the new build.
