I will get the current version, I'm on Github just now as it happens, I'm wary of just updating though as I have some modifications that I don't want to overwrite, just have to make sure I've got it all noted down.
If you are referring to modifications you made to Razuna via the UI then
all of those are saved in the database and you can simply make a backup
of the database and restore it after the update. If you keep the
webapps/razuna folder on Git all you have to do in the future is simply
git pull to get latest version and all your changes in Razuna will
remain as is.
