v1.319.0
Features
MFE vitals improvements
Implement quality of life improvements on the collection of MFE vital timings.
- If no FCP value is observed within 10 seconds, shut down observers for memory saving and outlier control.
- Decorate observed DOM trees with the MFE instance ID to facilitate debugging and prevent double-instrumentation of the same DOM tree from multiple instances pointed at the same MFE target.
Automatically Detect MFE Web Sockets
Add support for automatic Micro Frontend (MFE) attribution of WebSocket events. Previously, WebSocket events were only ever automatically captured globally by the container browser application. With this change, the agent cross-compares the call stack signature of the WebSocket method to the call stack signature of the MFE module that registered with the register API. If the file that is responsible for registering with the browser agent is found in the call stack signature of the WebSocket method being triggered, that event will be attributed to the MFE instead of the container.
Do not obfuscate attribute keys
Do not obfuscate attribute keys in our addCustomAttributes method for the BEL serializer. This change affects attributes in AjaxRequest, PageViewTiming, and BrowserInteraction (soft nav only) events.
Bug fixes
Avoid capturing agent AJAX payloads
Prevent the AJAX capture_payloads feature from capturing the agent's own telemetry requests (harvests to NR beacon endpoints).
Keep Ajax payload out of unrelated events
Drops captured AJAX request + payload info from unrelated events (AJAX timeslice metrics, session trace) via a shared params object.
Support statement
New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Older releases will no longer be supported when they reach end-of-life. Release dates are reflective of the original publish date of the agent version.
New browser agent releases are rolled out to customers in small stages over a period of time. Because of this, the date the release becomes accessible to your account may not match the original publish date. Please see this status dashboard for more information.
