Makers: when your UI changes, what goes stale first?

Makers: when you change your UI, what goes stale first: your demo video, your help docs, or your onboarding emails?

For us, keeping tutorial videos aligned with the latest UI is an ongoing challenge. Even a small interface change can make an older recording confusing when it shows a button or workflow that users can no longer find.

My guess is the demo video, because it is the one nobody owns. Docs get fixed when a ticket arrives. Emails get fixed when someone rereads them. A video just keeps showing the old button.

Curious how others handle it. Do you re-record on every release, keep videos short so a re-record is cheap, or skip video and rely on text?
