Release v2.2.0

[2.2.0] - 2026-06-22

Changed

• Perf card now derives its RTT sample size dynamically from the last hour's total recursive query count instead of a fixed config value - scales automatically with traffic, capped at the last 500 queries (freshest data for both low/high volume servers).
• Perf card now shows "waiting for data..." when no recursive queries are available to compute metrics instead of "collecting samples...".
• Perf card no longer displays the "X recursive samples" badge in the card header.
• Deprecated rtt.sampleSize configuration option - this is no longer required.

Fixed

• Dashboard no longer freezes after extended idle periods - all time range data (LastDay - LastYear) now correctly reaches the frontend regardless of which tab or chart option is selected.
• Query Chart and Top Stats now show fresh data immediately on tab return after being backgrounded, SSE reconnect, or server restart instead of displaying stale cached data.
