Business Insider just posted an article, here are some tidbits.


CBS News reported that Boeing said it had addressed these problems with updated software and would make these changes:
1. MCAS will now rely on readings from two sensors as opposed to just one in the original system. The new software will activate only if both sensors agree that the plane's nose is too high. Boeing had announced this updated this year.
2. Pilots will be able to override the system.
3. When they do so, MCAS will not automatically reactivate, which the original system would do multiple times.

........ Boeing also told stakeholders that it had flown 1,850 hours with the software updates and spent more than 100,000 hours engineering and test-developing them, CBS News reported.....
