I have just picked up today from https://incubator.duolingo.com/courses/tlh/en/status, from one month ago that the Klingon team released an notice, and I thought the community here may be interested to also know this.
ngop lubuy'moH wab chu' ("DISHing Up New Audio")
Two quick points, as we haven't issued an update in a while and I want you to know we're still working hard.
wa') The DHIS glitch has been fixed and the tlhIngan Hol team is racing to repair and provide the audio that we couldn't get to before. We don't have a new timeline for complete male audio, but it's still in progress.
cha') We're as sad as many of our learners about the closure of the Duolingo forums. We'll miss interacting with you, but know that we're still thinking of you, and that you can ask questions on the Learn Klingon Facebook group. The good news is that one of our forum moderators will now be working exclusively in the incubator to hatch a Klingon surprise for you.
