The version is confusing as the work in this branched off at around FOG 1.5.7 and has not been updated to 1.6.x for some time as it was still a very early alpha version not quite ready for production. It’s great to hear you have been using it for a year now already! We are still working on it and hope to release an official 1.6.x in the next months.
You can get the current stage of it as we work on it by checking out the branch working-1.6.
Let us know if there is anything that needs fixing.
