In the past, if someone was showering and the toilet was flushed. The water in the shower would go suddenly hot or suddenly cold.
Why did that happen? What changed to prevent it?

Many people just turn the toilet fill valves to be partially closed to prevent this. Then the cold water pressure diverted to the toilet is much less. Most toilets primarily use the toilet tank water for flushing and work fine with less input water pressure they just fill up the tank slower after a flush.
