This release includes the ability to build a cube with all it's related dimensions.
Note that the minimum supported version of Planning Analytics is now 2.0.8 (as opposed to 2.0.3 in 2.1-beta.1).
Since IBM has ended support for version 2.0.8 as of 30th September 2022, the decision was made to use a more robust and recent version of the TM1 Server to reduce bugs and take advantage of new features. In addition, we are now using Cubewise Arc for development, which recommends 2.0.8 or above.
If you are running an older version of the TM1 Server, you should update to a more recent one.
