v1.286.0
Features
Erase .api property on agent instance
The .api property of full and micro agents have been removed. The browser API methods are instead moved to the agent instance itself for ease of targeted access. This includes a minor fix of runtime loaderType for agents that are re-configured after load.
Reduce noise from mousemove events
There may be an edge case where a site performance can be impacted if the browser agent picked up mousemove events via addEventListener.
Handle duplicate agent APIs
Top-level interaction api calls are only responded to by the first exposed non-micro agent. This was changed to prevent issues for customers that run multiple agents together. The top-level interaction api should only be used to communicate with the main agent on the webpage. API calls on micro agents must instead be directly called on the respective micro agents.
Bug fixes
Patch newrelic event detail
There is an edge case where if there is a listener on the newrelic event (as described in the install docs) and any API call is invoked inside this listener, it will trigger an infinite loop.
Get string className for SVG elements
Change the nearestClass field for SVG elements to be a meaningful string name. The className of such elements is of type SVGAnimatedString and previously resulted in an empty object string.

Inspection events
Adds inspection events that detail when various agent-related events occur. These events can be listened to on the event listener 'newrelic' string type. Events include agent initialization, agent fully loaded, event buffered, event harvested, and api calls.
Bug fixes
Session Replay text masking for whitespace
There is an edge case where whitespace was being masked, which interferes with the layout/styling in session replays.
Logging mode on session update

v1.284.1
Bug fixes
Obtain FirstInteraction directly from performance API
To alleviate the potential performance impact of creating new performance observers to support legacy FirstInteraction timings, a change has been made to query the performance API directly for the presence of first-input data without the use of an observer at logical checkpoints.
Console error on some cross-origin requests without NR CAT header
XHR headers will be checked for the deprecated New Relic CAT header before calling getResponseHeader, which throws a console error if it does not exist for cross-origin requests.

v1.284.0
Features
Remove FID, replace first interaction detection with INP
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 INP event and will no longer output value for the firstInputDelay attribute. 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.

Guard against non-CSSStyleSheet when fixing sheets for replay
Nullish values in the global styleSheets API can break implementations with the weakMap object tracking their status, throwing an error similar to TypeError: Invalid value used in weak set at WeakSet.add.... This fix checks that the value is acceptable before adding.

Features
Add global custom attributes to log data
Add custom attributes set by the setCustomAttributes method in Browser Agent API to logging data. These attributes are in the common.attributes section of the outgoing payload. Local custom attributes set by the log and wrapLogger APIs take precedence in the backend over the global custom attributes set by the setCustomAttributes API.
Add auto-logging feature
Introduces automatic observation of browser console methods to capture logging statements from the browser console across a given session automatically. On/off, logging level, and sampling are controllable via the application settings section of your browser entities. Check the getting started guide for more info.

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.
