Ahoy there, fellow software enthusiasts!
My updater project has made rapid progress and is taking shape where I can soon announce beta status.
Take a look at the sources here https://github.com/nefarius/vicius
Also check out the documentation and especially the API documentation here https://docs.nefarius.at/projects/Vicius/Remote-Configuration/
Last but not least do not be afraid to make feature requests or comment on my choices, will enable the issue tracker today.
Cheers!
