move upstream branch from sourceforge to github #36
It looks like new development(after version 5.3) in the upstream will no longer be open-source. This is questionable, as the original license specified was GPL and other authors besides Sindre Mehus have contributed code. I do not believe that going closed-source for releases in that manner is allowable, but I do not have the resources to fight it.
If no further changes will be coming down from upstream then I will review the CONTRIBUTING policy for this repo and look into making it a full-fork+rebrand(eg, to LibreSonic). This is not an optimal solution as far as I'm concerned, but I will continue to support this software for my own internal usage indefinitely and make those efforts available to the community regardless.
The 6.0-beta1 that is currently out under Releases is in a usable state, and contains the majority of what I believe is in upstream's official 6.0. You can use that while a path forward for this project is determined.
I have alerted the FSF to the possible GPL violations with other authors that contributed code under GPL. It's doubtful it'll result in any legal recourse if Sindre Mehus is actually misusing the license, however they have a loud voice and may alert/warn others of subsonic's shenanigans.
