Important Changes

• deprecated

  hono: Promote @sentry/hono to stable and deprecate honoIntegration

  The @sentry/hono SDK is now stable. See the Sentry Hono SDK docs to get started.

• hono: Add shouldHandleError option to sentry() middleware

  The sentry() middleware now accepts a shouldHandleError callback to control which errors are captured and sent to Sentry. By default, 3xx/4xx HTTP errors are ignored and 5xx errors and plain Error objects are captured. Return true from the callback to capture an error, false to suppress it.

  app.use(
    sentry(app, {
      dsn: '__DSN__',
      shouldHandleError(error) {
        const status = (error as { status?: number })?.status;
        // Capture 401/403 in addition to the default 5xx errors
        return status === 401 || status === 403 || typeof status !== 'number' || status >= 500;
      },
    }),
  );

• tanstackstart-react: Add distributed tracing

  Server and client traces are now automatically connected, allowing you to see the full request lifecycle from server-side rendering through client-side hydration in a single trace.

• tanstackstart-react: Add server-side route parametrization

  Server transaction names are now parametrized automatically (e.g., GET /users/123 becomes GET /users/$userId), improving transaction grouping in Sentry.

• tanstackstart-react: Show readable server function names in traces

  Server function spans now show human-readable names (e.g., GET /_serverFn/greet instead of GET /_serverFn/a10e70b3...). The tanstackstart.function.hash.sha256 span attribute has been renamed to tanstackstart.function.id.
