Why does the fmincon optimization give a slightly different solution in MATLAB 2019B as compared to 2020B?

I have noticed that I get a different solution when using the fmincon function as compared to my colleague (he has 2019B and I have 2020B). We ran the exact same code, with the same initial conditions and constraints.
Do optimizers like lsqlin or fmincon have different optimization routines based on the MATLAB version?

Many things change in each version. The usual issue is that the underlying math libraries can have slight differences. Optimization routines iterate, and these minute differences can be amplified. You might also notice slight differences when running the same routines and versions on different hardware.
