v1.281.0
Features
Capture Nearest UserAction Fields
The UserAction feature has been extended to capture "nearest" field values when the UserAction target does not include the desired fields. To facilitate this, a configuration was added allowing the user to control what fields are collected, specified as init.user_actions.elementAttributes: []. When empty, no extra fields will be collected. When supplied, the target will be checked for each property. This configuration defaults to ['id', 'className', 'tagName', 'type'], which matches the fields captured before this change.
For each elementAttribute defined, if the property is not found, the agent will search up the parent tree of the target element, until the property is found. If found up the parent tree, a property called "nearest" + fieldName will be added to the event.

v1.279.1
Bug fixes
CLS timing node not being reported post new Harvester
Reintroduce the cumulativeLayoutShift timing of PageViewTiming events into EoL harvests. After v1.278.0, this timing stopped being sent when the user leaves the page, resulting in a drop in CLS counts. The node contains attributes that aid in identifying the cause of bad scores.

v1.279.0
Features
Remove FID
First Input Delay (FID) has been deprecated and replaced by Interaction To Next Paint (INP). PageViewTiming events for first interactions are preserved by detecting the first first-input event and will no longer output value for the firstInputDelay and loadState attributes. For more info on PageViewTiming, see https://docs.newrelic.com/docs/browser/new-relic-browser/page-load-timing-resources/pageviewtiming-async-or-dynamic-page-details/. For more info on INP and the FID deprecation, see https://web.dev/articles/inp.
Debounce window user actions
Debounce focus and blur events on the window for 500ms to prevent duplicate events from being harvested. All major browsers have their own quirky behaviors that generate duplicate blur and focus events under some conditions. This change ensures that only 1 blur or focus event can be captured every 500ms to reduce noise.
Capture details in marks and measures
The detail property of PerformanceMark and PerformanceMeasure events will now be captured in New Relic BrowserPerformance under the entryDetail attribute. If detail is an object, it and any nested objects within it will be flatten into string path keys prefixed with entryDetail. See the PR for elucidation.
Add HTTP codes for harvest retry attempts
Agent will begin to retry harvests to the endpoints that failed for the following additional status codes: 502, 504, and 512-530. This is suggested by New Relic ingest teams as a possibility to recapture lost data in these marginal cases.

v1.278.3
Bug fixes
Change obfuscator to read dynamically from configuration
Fix an issue where obfuscation rules are not honored if added after the agent has initialized. Some user cases require obfuscation rules to be dynamically added, this change will allow that behavior -- as long as the obfuscation rules are added to newrelic.initializedAgents[index].init.obfuscate

v1.278.2
Bug fixes
Allow the page view feature to have access to an event buffer
Fix an issue where if the page unloaded before the page view feature could "block" itself from future harvests, an undefined error could be thrown when the harvester tries to access each feature's event buffer. The page view feature now has access to the event buffer, to prevent that undefined check. The event buffer will remain empty, since the page view feature does not carry state. This change rectifies an issue observed in 1.278.1.

v1.278.0
Features
Centralized harvesting
Introduces a singleton harvester tasked with sending feature payloads rather than each feature utilizing their own scheduler. This reduces runtime space usage and the number of timers which proportionally scales as the number of features increases.

Features

Add a new API - recordCustomEvent(eventType, attributes). This allows any custom-defined eventType to be stored in NRDB. Check the API documentation for more information.
Bug fixes
Soft navigation bug fixes and new soft navigation tests
Fixes several issues tied to the soft navigations feature. Calling newrelic.interaction() prior to a page load now creates a separate "api" trigger node. Multiple interactions managed simultaneously now have correct timings. Fixes a bug in soft navigation, where API-triggered interactions fail to close under default heuristic (URL + DOM change), because the mutation observer is not started. Finally, 'popstate' events are now valid interaction triggers for soft navigations.

v1.276.0
Features
Allow feature flags to control experimental features
Use internal feature flags to control experimental features, reducing your effort and supporting APM-injected installations.
Capture Page Resource Assets
Add detection for page resource assets that captures data as a BrowserPerformance event. This feature is being shipped in an experimental state and is off by default. To opt in to using this feature, it can be turned on by setting the config value init.performance.resources.enabled = true in Copy/Paste or NPM installations.
Bug fixes
Ignore reserved attribute names on UserActions tied to the window
Force the agent to not capture target-level attributes for window-level UserActions. You can set window-level variables that mimic HTML element attributes like type or tagName. This change prevents the potential capture of those attributes as part of blur or focus user actions tied to the window.
Fix syntax error in fallback when tracking xhr readyState
Fixed the syntax error that would cause xhr readystate fallback checks to always capture.
