Haven't they also fitted multiple stall sensors, so that the computer won't make decisions on the input from only one?

Well, they had multiple stall sensors before (angle-of-attack sensors actually, which can be used as stall sensors.) But the MCAS was only looking at one. Now it looks at both AND it has a warning when they disagree, indicating one is damaged - and when that happens the MCAS does not take input from either one.

Other changes that were not as directly related to the crashes:

Improved wiring to the horizontal stabilizer trim system
Improvements to the software in the flight control computer
More mandatory training for new pilots

I believe pilot training has been improved, particularly in case of MCAS failure.
