Where did the Simulink model history go to?

Due to toolbox support we had to switch from Matlab 2019a to 2021a.
I was using the history tab in Simulink to keep a good track of all the modifications that are being made to our model.
Since Matlab 2021a i noticed that this information is not visable anymore.
Does someone know if this has been moved to a different location? I cannot find this in the documentation of Matlab changelog.
The attached picture is the tab view from Matlab Simulink 2019a.

Hello,
Starting in R2021a, the Model history field and the Prompt to update model history option in the Model Properties dialog box have been removed. It is still possible to query the ModifiedHistory parameter, and enable the prompt to update behavior by setting the UpdateHistory parameter.
For more information refer to Release Notes. (R2021a -> Project and File Management -> Functionality Being Removed or Changed)

Is there a reason why this was replaced?
We found it quite intuitive to document the development of our models directly inside the model with the Update History When Saving prompt. We do also apply version control for the development, but for smaller model change steps applied, it was nice to have the list from the model history.
Is there another metadata or recommended way for documentation that we could use for this?
Thank you very much in advance

I agree with Korbinian Volgt.
The Model History feature was very helpful to track the changes to the models. We implemented our report generation to publish this info in the model documentation (using R2020b). It seems it will not work anymore in later releases which is really a shame.
Is there another metadata or recommended way for documentation that we could use for this?
Thank you very much in advance
