    • Frustration signals - dead clicks detection #1697
      • Detects when a user clicks an interactive element (button, link, or submit input) that produces no meaningful response — no DOM mutation and no network activity within a configurable time window
      • Enabled via instrumentations.frustrationSignals.deadClick: true or with custom options (timeWindowMs, ignoreUrls)
      • Default detection window is 1000ms
    • Frustration signals - error clicks detection #1681
      • Detects when a user clicks on a UI element and a JavaScript error occurs shortly afterward
      • The frustration span captures the error message, error type, clicked element, and links to the original click and error spans
      • Enabled via instrumentations.frustrationSignals.errorClick: true or with custom options (timeWindowMs, ignoreUrls)
      SplunkRum.init({
	instrumentations: {
		frustrationSignals: {
			deadClick: true,
			errorClick: true,
		},
	},
})
    • Add _experimental_adjustSessionStartToTimeOrigin config option #1705
      • Backdates session start time using performance.timeOrigin to reflect when the tab opened rather than when the SDK initialized
      • Drops spans whose start time predates the session start time by not assigning a session ID
      • Anchors session.start span to the precise session start moment
    • Use nanoid for IDs to prevent collisions #1701, #1752
      • Cryptographically secure ID generation using nanoid is now used by default for all IDs, preventing duplicate session IDs from Googlebot's seeded Math.random()
    • Add retry strategy for anonymous user ID persistence #1703
      • Adds write-back verification with retry capability (up to 3 attempts) when persisting the anonymous user ID cookie
    • Fix init session missing from sessionHistory and notifications #1747
      • Session initialization now follows the same processing path as subsequent updates, ensuring the initial session is added to sessionHistory, persisted to storage, and triggers subscriber notifications
    • Fix timestamp of webvitals spans #1700
      • Fixed incorrect start times on web vitals spans when experimental_alignWebVitalsSpansWithDocumentLoad is enabled

⚠️ Upcoming breaking changes in v3.0.0

Action required before upgrading to v3.0.0:

  • Domain migration: All domains are changing from signalfx.com to observability.splunkcloud.com. This includes both the CDN (cdn.signalfx.com → cdn.observability.splunkcloud.com) and the ingest endpoint (rum-ingest.{realm}.signalfx.com → rum-ingest.{realm}.observability.splunkcloud.com). If your application uses a Content Security Policy (CSP), update your script-src and connect-src directives to allow the new domains before upgrading.
  • latest CDN tag discontinued: The latest CDN tag will stop being updated after v2.5.0. Users relying on the latest tag should migrate to a versioned URL:
- <script src="https://cdn.signalfx.com/o11y-gdi-rum/latest/splunk-otel-web.js"></script>
+ <script src="https://cdn.observability.splunkcloud.com/o11y-gdi-rum/v3/splunk-otel-web.js"></script>

The following experimental config options will be removed in v3.0.0 and their behavior will be enabled by default. This may affect how sessions and data are counted:

  • _experimental_adjustSessionStartToTimeOrigin: Session start time will be automatically backdated to performance.timeOrigin.
  • _experimental_discardDataAfterInactivity: Will be enabled by default. Data will be automatically discarded after 15 minutes of user inactivity. Set _experimental_discardDataAfterInactivity: false to opt out.
  • OTLP exporter enabled by default: The OTLP exporter will replace Zipkin as the default export format. Set exporter.otlp: false to opt out.
  • spaMetrics: Will be enabled by default. Set spaMetrics: false to opt out.
  • experimental_alignWebVitalsSpansWithDocumentLoad: All web vitals spans (LCP, CLS, INP) will be automatically anchored to the document load span — start time will match the documentLoad span timestamp rather than the time the metric was reported, and location.href will reflect the original page load URL rather than the current URL after SPA navigation.
