I didn’t find anything on InfoSys on how to check this. You can pin/fix the project version, but this only changes things on the XAE side, not on the runtime.

I want to check the XAR version, because of a feature that was introduced in 4024.40. I want to make sure that this feature is available.

But now I’m wondering if it is necessary to have the runtime at a newer version as well. According to this question, a later XAE version compared to the XAR is ok. So in that case I can just upgrade the XAE version.
