Should you use a log or a metric?
Logs and metrics look nearly identical when you're instrumenting code. Using a signup handler as the example, here's how to tell which question each one answers, and when you can just count the logs.

Sentry's Flutter SDK 10.0 makes streaming traces the default, fixes crash-free rate accuracy for unhandled errors, and adds dedicated app startup traces on Android and iOS.
Product Updates
Sentry JavaScript SDK v11 adds tracing for all JS platforms
The OpenTelemetry instrumentation packages needed a Node module loader, a package.json file, and a mutable exports object. v11 replaces all of that with a source transform and diagnostics channels, so tracing now works on Cloudflare Workers, Bun, Deno, and bundled server deployments.

Reducing Android scope-sync overhead in Sentry Flutter
We moved Android SDK operations to a worker isolate, then streamlined scope updates by removing duplicate normalization and encoding JSON directly into UTF-8 bytes.
