TL;DR: First release of Helium! Please try it out and reports issues at https://github.com/phako/Helium/issues or as a comment if you don’t want to register with github,
This version is not submitted to the store (yet) since I felt it needs a bit more testing, especially on the interaction with media renderers. I’ve only two renderers that are not Rygel-based and one of them is severely broken when it comes to UPnP.
So please, try it out and report any issue you find either via its issue tracker at github or as a comment here.
Basic usage instructions are available on this site.
