The 4.2 rollout shaved the p99 across the board. Edge collectors now batch with jitter, and the ingest path skips two serializations we'd been carrying since 2023.
Autocomplete now learns from your last 30 days of queries. It suggests the next clause before you finish typing — and it's workspace-local, so nothing leaves your region.
Pin a query to a service, a team, or a dashboard. Saved queries now version themselves — if someone overwrites one you rely on, you'll see the diff.
Tell Pulse when you're shipping and the expected spike goes quiet. Alerts outside the window still fire, so a rollout gone sideways still gets you up.
Pin a span and the cursor locks to its window in traces, logs, and metrics. Good for incidents. Better for explaining incidents to someone who wasn't in the room.
Fixed a gnarly memory leak that showed up only under batched OTLP/HTTP traffic with gzip on the receiving side. Running longer than 72 hours? You'll notice.
A full year of rewriting the ingest path. Your queries don't change. Your dashboards don't change. Your bill doesn't change. Everything underneath does.
