They spent a long time checking out everything on the Wentian before swinging it over to it's final position. Mengtian was moved earlier today.

I'll guess the longer time period for Wentian was due to it having a full backup of life support (including 3 crew bunks and it's own toilet, which allows the station to have up to 6 people on board at a time). I guess they wanted to make sure all of that was in good working order before moving it to its permanent place. Mengtian is purely a science module, so it's a bit simpler in terms of integration with the systems in the other 2 modules.
Next up will be another cargo ship sometime late this month and then the next crew arrives on Shenzhou 15 in December. This will be the first crew handover.
The next piece of hardware planned is the Xuntian space telescope. It will co-orbit with the Tiangong station and can dock with it for maintenance and upgrades. The planned launch is late 2023 or early 2024.
There is one other intriguing possibility under consideration. Each of the 3 modules has a twin still on Earth. Initially, these were created as a backup in case one of the first set was lost in a launch accident. It would be very easy to launch them to double the size of the station, allowing it to host 12 people at a time. Since the plan is to host many foreign guest astronauts, I'll bet that whoever in charge of scheduling those visits would be greatly relieved if the station could hold twice and many people and twice as many cabinets for experiments.
