Each plan now shows its own length of history

How far back you can see your monitoring history now follows your plan: 14 days on Free, 1 year on Pro, 2 years on Business and Agency, and 3 years on Enterprise. That applies everywhere history appears: status page uptime bars, the status badge and incident history, LiveStatus walls, the monitor page, the dashboard, the security score trend, SLA reports and the API's uptime and check results.

• Nothing is deleted. Your history stays stored whatever your plan, and it is shown again as soon as you move to a plan that covers it.
• On Free, a status page shows 14 daily bars instead of 90, and the dashboard's uptime tile covers the last 14 days.
• Reports start no earlier than the first day your plan shows, and the preview tells you when a report was cut short.
• The API cuts a longer days to your plan's window and says so in window.history_days.
