v1.303.0

Features

Allow consent API to be invoked without localStorage access

Allows the consent API to function without requiring localStorage access, by keeping common state in the agent that controls harvests. Applications must invoke the API on every hard page load when localStorage access is blocked.

Allow nested registrations

To facilitate inherent parent-child relationships with the planned register API, allow registered entities to expose their own .register() API for children of that entity to register with. Entities who register with the container agent will be related to the container. Entities that register under another registered entity will be related to both the container as well as the parent entity.

Additional validation to prepare agent for MFE registrations

Adding validation rules in the agent to prevent bad values for MFE target id and name in support of MFE/v2 registrations.

Add measure support to register API

Adds support for the measure API in the register response object. This is in support of the future micro front end offering planned.

Add useConsentModel functionality

Adds use_consent_mode init property and functionality. Adds the consent() API call. The consent model, if enabled, disallows agent harvesting unless consent is given through the consent() API call.

Retry initial connect call

To help prevent data loss, the agent will now retry the original "RUM" call an extra time for retryable status codes.

Add custom event support to register API

Adds methods for capturing custom events to the register API, to be used later when MFE support is established.

SMs for browser connect response

Adds supportability metrics for failed responses on initializing the page_view_event aggregate.

Bug fixes

Obfuscate custom attributes for logs added after PVE

Extends obfuscation to cover custom attributes on logging events added after the initial RUM/PageViewEvent harvest.

memoize promise context propagation to avoid safari hangs

Memoizes promise context propagation to prevent potential browser hangs in Safari by avoiding repeated context operations.

v1.302.0

Features

Prepare agent to utilize v2 harvests for MFE registrations

Update the agent to handle harvests for registered targets to use the newly defined v2 endpoint schemas. This will act as the mechanism to handle client-side entity and relationship synthesis as well as ingest MFE specific data. This will be supported for Log, PageAction and JavaScriptError events, but is currently gated behind internal feature flags until a public preview is announced.

Bug fixes

User frustrations logic should be gated

Move user frustrations logic to browser scope only with FF gate in Generic Events instrumentation. This should avoid running extraneous wrapping logic and events related to user frustrations.

Improve accuracy in standalone AjaxRequest event start times

Adjusts a problem in the agent where start times of certain standalone AjaxRequest event payloads were reported relative to the page origin instead of relative to the first event in the payload, causing discrepancies when visualizing in NR1.

v1.301.0

Features

Switch to using NR fork of rrweb

Browser agent will now switch to using New Relic's forked version of rrweb for Session Replay instead of the original repository. This will allow browser team to custom tailor hotfixes for issues.

Bug fixes

Preserve agent attributes for log payloads

Adjust browser log payloads, such that agent-reserved attributes will take precedence over user-provided values if they happen to share the same name.

v1.300.0

Features

Remove usage of the marks and measures feature flag

No longer gates the agent by an internal feature flag. Measures will be enabled for all users by default unless turned off through the application settings.

Reduce hasReplay attribute false positive rate

Only set "hasReplay" attribute once a successful session replay harvest has been observed to help reduce false positives.

Bug fixes

Update typings for interaction API to reflect waitForEnd

Fixes an issue where the typing file defining the .interaction API was not decorated correctly to account for the optional waitForEnd argument as documented.

Address issues with dynamic require and Rollup.js

Fixes an issue that led Rollup.js to spawn the error Error: Could not dynamically require ... when building pages that included the MicroAgent loader.

Features

Add Flutter supportability metric

Introduces a supportability metric to track browser agent usage in Flutter web applications.

Add user frustration signals to UserAction

Provide better insight into potential user frustrations for specific user actions via dead click and error click detections.

Evaluate the accuracy of cross-feature attribution

To support internal improvement benchmarks, add supportability metrics that evaluate the accuracy of attributes that indicate the state of a separate event, such as hasReplay or hasTrace.

Bug fixes

Fix recordReplay API inconsistencies

Fixes an issue where a late-called recordReplay API call would not successfully harvest data.

v1.298.0

Features

Factor long tasks into soft nav base interaction span

BrowserInteraction under soft navigation ("SPA 2.0") will extend in duration beyond DOM modification time until the point wherein no long tasks have been observed for 5 seconds. JavascriptError and AjaxRequest are not yet associated with such interaction during this extended period beyond the end of the original heuristic.

Bug fixes

Force LCP to report the original page URL

Allow LCP to report its pageUrl distinctly from the harvest URL. An issue was observed where soft navigations occurring before the LCP harvest would report the current page URL instead of the original page URL tied to LCP. This change allows LCP harvest nodes to report the original URL, regardless of the current page URL. The change should apply both to the pageUrl and targetGroupedUrl attributes.
