@mikenomitch you should have context here, can you take a look? |

| - The runtime will no longer reuse isolates across worker versions even if the code happens to be identical. This "optimization" was deemed more confusing than it is worth. |

This one feels a bit too internally-focused to add. If there's a reason the end user should care about this, I'm happy to keep it, but feels like an implementation detail.
But, not a blocker IMO, so if there's a good reason why people would care, feel free to merge.

@kentonv is this fix something that is observable to external developers? Happy to keep the message, just want to make sure it's relevant to customers.

Yes, this is totally observable to external developers. We've seen a fair number of instances of workers that have bugs when env changes without reloading the isolate, and we've made efforts to inform people that this can happen. Anyone who previously learned that may be interested to know that it is no longer a concern.

Sounds good, thank you for elaborating!
