Release Notes

Notes: Added process.getSystemVersion(), which is available in sandboxed renderers and returns the actual operating system version instead of kernel version on macOS.

As a procedural matter it might be good to put this up for an emoji-vote on #pineapple since it adds a new feature to a stability branch.

That said, I'm 👍 on this PR

[ckerr]

Hmm actually my last review sends a mixed message of approving + asking for further work.

So I'm giving a "Request changes" here solely as a procedural step of getting team feedback on adding a semver/minor feature to 5-0-x

[miniak]

@ckerr, @nornagon I've removed the target/5-0-x label + added the example values. Can you please approve?

if we're only targeting master, the question of semver/minor is moot
