v1.258.0
Features
Restructure AJAX Aggregate
Re-organization of the Ajax feature as part of agent maintenance. This has no expected impact on its functionality.
Maintain calculated NR server time for session
This update changes the agent to store the New Relic server time calculated when session tracking is enabled. This will prevent the agent from re-calculating server time on subsequent page loads, ensuring the timeline view of events in New Relic is more accurate.
Add harvestId to Session Replay payloads
Adds a unique harvest ID to Session Replay payloads to support better indexing and querying on the platform.
JSErrors timestamped per harvest
JSErrors that happen multiple times throughout a page's life will now receive a timestamp unique to the agent harvest cycle instead of consistently reporting the timestamp of the first occurrence of that error.
Bug fixes
Clean up xhrWrappable
Remove xhrWrappable which is an old variable checking for addEventListener on XHR. It is expected to have no compatibility impact on modern standard frameworks or browsers.
Prevent null CLS
Add a check to prevent null and undefined web-vitals values from being reported.
Support statement
New Relic recommends upgrading the agent regularly to ensure you get 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.
