How to update?

[abrogard]

The system told me I was out of date.
So I downloaded SAS.Planet.Nightly.24023.10649.7z
Now what do I do? Unzip that where it is? Unzip it on top of my existing version? Unzip it somewhere else? Anythings I should apart from unzip?

Unzip it on top of my existing version?

Yes, unzip with replace existing files. That's all you need to update.
