• mldonkey-next - modern client for mldonkey - LinuxLinks

  The project grew a bit more than intended, and now includes multiple projects:

  docker-mldonkey: docker image containing a patched version of the mldonkey core. This includes patches that allows the mldonkey-next webapp to show more info. mldonkey fork: some changes to the mldonkey core were needed. I keep upstreaming my patches, but the official mldonkey project is pretty slow. mldonkey-next: the webapp and the native wrappers.

  This is free and open source software.
