[Question] Updating Part-DB manually, i.e. without using git.

[amitzioni]

Hey,

I'm currently running Part-db 1.12.0

I've installed Part-DB not by using git clone, but rather by downloading the tar.gz archive from the releases page and unpacking it.
Now I've got a notification that version 1.13 is available, however in the documentation the only way mentioned for updating is by using git checkout, which doesn't work when you download the archive from the release page.

What would be the correct way to update to 1.13 without using git ?
