DIfferences in MLR between v3.01 & v3... PreviousNext

I originally began working on a project using the MLR estimator in Mplus version 3.01. Recently, the software I was using was upgraded to MPlus version 3.12. It is my understanding that the numerical integration algorithm has changed in this new version.

So my question: If a model is run in v3.01 using MLR with 10 integration points, will the results be the same if the same model is run in v3.12 using MLR with 10 integration points. That is, will syntax that is identical produce different results between versions?

The results will be in most cases very close but the speed of estimation will be faster. Most of the changes involved speed improvements. Algorithms were also robustified to improve convergence.
