Gourmet continues to move toward greater stability with version 0.15.9 being released. The plugin architecture is fully in place and mature now, as well as an experimental web front-end. Gourmet sources are available on SF here (https://sourceforge.net/projects/grecipe-manager/files/), and .deb files are now available through a PPA here: https://launchpad.net/~thomas-hinkle/+archive/gourmet
The windows executable is still a few version behind. We are always looking for more windows devels/testers to help.
