It leaves out one important thing:

The choice of the death type is dependent on sim's age and occult status.

For example, for sims, Death by Old Age wasn't listed there. That's because only one age was looked at. If the sim is made into an elder, Death by Old Age becomes available. Not to mention that children can only have either fire death or drowning death (even though they can also die by steam, pufferfish, freezing, and overheating).

With occults, Death by Sunlight and Death by Overcharge wasn't mentioned. These need the sim to be a specific occult first (vampire and spellcaster respectively). In addition, occult status blocks out some deaths for sims. For example, vampires cannot die by broken heart.

And... Other thing that also wasn't mentioned is that death by old age not only got its description changed, but also new interactions.

But to the description. This was the old description:

This Sim died when their time was up.

And this is the new description:

No need for sorrow, this is the result of a long, long life.

Interesting to see old age ghosts see some new gameplay...
