## From the publisher

You can now monitor how much memory your Workers and Durable Objects consume across invocations with the new Memory Usage chart in the Workers Metrics tab, broken down by P50, P90, P99, and P999 percentiles. Memory usage measures the V8 isolate memory at the time of each invocation, subject to the 128 MB per-isolate limit — a single isolate can handle many concurrent requests and shares memory across them. Use the Memory Usage chart to: Track memory trends — Spot gradual increases that may indicate a memory leak before they cause Exceeded Memory errors. Correlate with deployments — Deployment markers on the chart help you identify whether a new version introduced a memory regression. Right-size your Worker — Understand your baseline memory footprint and how much headroom you have before hitting the 128 MB limit.
