These questions are being asked on a daily basis, but for the sake of new users we will repeat the answer once again.
The next feature to be released is Trust Dungeons support.
There is no ETA, but we are working non-stop and doing our best to release updates as fast as possible.
Triple Triad is still coming and we will be working on it after we implement the core Combat system. During the past 3 years the demand for Triple Triad did not exceed Combat system, so its priority remains the same. The Combat system requires full focus from our developers, therefore no progress will be made on Triple Triad until then.
For future updates, please refer to the main status thread: Shadowbringers – Miqobot Status
