As far as I know, once the feature is fully finished (currently notifications when receiving a challenge are not implemented).

Not really but I got sidetracked by all the PRs to review and other priorities that arised in the meantime (feedback from bullet players about the reactivity of the board that I deemed important enough to work on a major change of chessground regarding the event listener).
I will try to make a release very soon and after that I will resume the work on challenges. Receiving challenges will involve local native notifications which is also not trivial to set up. That's why I prefered to make an intermediate release before finishing it, to release sooner.
