Browser agent release notesRSS

April 14
Browser agent v1.313.0

v1.313.0

Features

Automatically Detect MFE Errors

Add support for automatic Micro Frontend (MFE) attribution of JavaScriptError events. Previously, JavaScriptError events were only ever captured globally by the container browser application. With this change, the agent cross-compares the stack trace of the thrown Error instance 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 stack trace of the thrown Error instance, that event will be attributed to the MFE instead of the container.

remove "withCredentials"

Remove all usage of withCredentials or credentials: 'include' from agent harvests, as cookies have not been used in the agent since before v1220.

Improve MicroFrontEndTiming heuristics

Improve the ability to detect script execution times for MFE, leading to more accurate timeToLoad metrics.

Report CSP violations as new events

Content Security Policy (CSP) violations bubbled up are now captured and reported as a new SecurityPolicyViolation event type to Page Insight consumer. They become query-able through NRQL.

Ensure the register API complies to company requirements before exposing for limited preview.

Bug fixes

Bad trace.lastTimestamp in Safari + back nav edge case

Fixes a race condition where Safari browser's back navigation (BFCache) could cause absolute timestamps to be recorded at the start of the session trace feature, resulting in an abnormal trace.lastTimestamp value and a mix of relative and absolute timestamps in a single payload.

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.

Browser agent v1.312.0

v1.312.0

Features

Automatically Detect MFE Logs

Add support for automatic Micro Frontend (MFE) attribution of Log events. Previously, Log 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 given log method (such as console.log, console.info, etc.) 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 log method being triggered, that event will be attributed to the MFE instead of the container.

Automatically Detect MFE AJAX

Add support for automatic Micro Frontend (MFE) attribution of AjaxRequest events. Previously, AjaxRequest events were only ever captured globally by the container browser application. With this change, the agent cross-compares the call stack signature of the AJAX call 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 AJAX request being triggered, that event will be attributed to the MFE instead of the container.

Bug fixes

Session replays not working for Angular app running on Safari

Fixes an issue where session replays would fail to capture any recordings beyond an initial snapshot for Angular apps running on Safari.

Revert circular replacer

The circular replacer method applied to JSON.stringify operations was seen to cause lag in niche cases with deeply complex and nested objects emitted in quick succession such as in scroll event handlers. This method was revert back to a faster simpler operation to decrease performance bottlenecks.

Browser agent v1.311.0

v1.311.0

Features

agentIdentifier removal

Removed scoped references by agent identifier to simplify the agent architecture. All references are now stored directly within the agent reference, eliminating the need to blend agent references with scoped objects via lookup keys.

Attribute original page URL to all PageViewTiming nodes

Expanded pageUrl attribution to all timings, building on previous work for LCP. PageViewTiming events now report the original hard navigation URL for all node types, ensuring data consistency for SPA even if the URL changes before harvest.

improve MFE timing logic

Enhanced the agent's ability to identify the correct MFE script calling the register API. This improvement results in more accurate timing information for MFE environments.

Bug fixes

Enforce string IDs for new MFE registrations

Resolved an issue where non-string IDs caused errors during MFE entity synthesis. The agent now enforces string-based IDs and issues a warning if a different data type is provided.

Circular replacer removed reused objects from harvests

Fixed an issue where the internal stringify method removed shared pointers across harvest payloads, which occasionally caused missing params attributes on error harvests.

Update RegExp to prevent un-minimized webpack build issue

Replaced the $ character with its hexadecimal equivalent in regular expressions. This prevents Webpack from incorrectly replacing the character during the build process, which previously caused agent failures in unminimized builds.

Browser agent v1.310.1

v1.310.1

Bug fixes

February 17
Browser agent v1.310.0

v1.310.0

Features

better MFE timing handling

Improve the detection of script assets reported by the browser which power the MicroFrontEndTiming event's timeToFetch and timeToBeRequested attributes. This change also includes new assetUrl and assetType attributes to better illustrate the assets used to populate the timing data.

This concludes the complete removal of the old SPA feature that is replaced by Soft Navigations feature. Since agent version 1.307.0, the default "SPA" was already switched over, so no breaking changes from this version are expected.

Capture MFE timings as MicroFrontEndTiming Events

Captures the lifecycle timings of registered entities in preparation for future micro front end product

Bug fixes

Update measure API types

Corrects an issue where the typings associated with the measure API did not accept PerformanceMark as a valid input for start or end values.

February 3
Browser agent v1.309.0

v1.309.0

Features

Warn when more than one agent is running

Added a console warning when more than one Browser agent is running on the page.

Improve MFE tag setting

Enforce tags to be set for micro frontends by supplying an object of key-value pairs to the tags argument of the register(...) API. This allows for tags to be specified with an explicit value instead of only supporting boolean tags.

Add WebDriver detection attribute to PageView & PageViewTiming

PageView, PageViewTiming and initialPageLoad-category BrowserInteraction events will now report a webdriverDetected property corresponding to the navigator.webdriver set by the browser.

Bug fixes

Micro agent duplicate handlers

Fixes when micro agents are created in a staggered fashion, handlers for each agent is multiplied by the number of agents that follow. For example if there were two agents, the handlers for the first agent was registered twice. This had the effect of duplicating events + contents of harvest payloads.

allow child registrations from blocked parents

Allow blocked parent entities to still instantiate a child MFE when registering
