Browser agent release notesRSS

October 10, 2023
Browser agent v1.244.0

v1.244.0

Features

Bump rrweb to 2.0.0.11 and make constant dynamic at build time

Bump rrweb dependency version to 2.0.0.11 and include in Session Replay payload metadata dynamically

Add Session Replay configurations to collect inline assets

Add Session Replay configurations to collect inline images, stylesheets, and fonts for private applications.

Browser agent v1.243.0

v1.243.0

Features

Do not report ajax nodes in session traces if in deny list

Prevent ajax nodes derived from calls found in the ajax deny list from populating Session Trace payloads

Remove deprecated API inlineHit

Removing the browser agent API inlineHit. This API was deprecated in 2014 and is no longer supported or used by newer versions of the browser agent.

Bug fixes

Re-update assets proxy to accept host URL strings

Previously, the agent expected the protocol (for example, https://) to be included in the configuration input. However, we have since decided to allow the protocol to be excluded, as the proxy beacon field only accepts a host string.

Adjust Session Replay meta and timestamps

Ensure that payloads can not ends with a meta node or start with a snapshot node for consistency in UI render queries.

Tap session entity into storage API for changes across tabs

Tap session entity into storage event listener for stateful changes across tabs.

Set Session Replay first chunk flags more reliably

Add logic to set firstChunk flag and replay mode on new replays more reliably.

September 25, 2023
Browser agent v1.242.0

v1.242.0

Features

Add messaging about Session Replay abort behavior

Add messaging to signal why a replay aborted, which could happen for a number of reasons.

Applying new cache headers to assets

Released browser agent assets will now be delivered with a 1 year cache header. This will allow user's browsers to cache the async chunks the agent loads for much longer and eliminate performance recommendations found in synthetic performance tools like Lighthouse. This will be applied retroactively to all released versions of the agent.

Bug Fixes

Drain event emitter even when feature fails to initialize

A failure to import and initialize a feature could block the agent from draining data out of the event emitter, which prevents the agent from making any successful calls. This fix allows the event emitter to drain even when an individual feature fails to initialize.

Validation of SR configurations

Update the block selector, mask selector, and mask input setters to handle empty strings.

September 18, 2023
Browser agent v1.241.0

v1.241.0

Features

Add SR entrypoint to NPM ahead of LP

Add SR instrumentation entrypoint to NPM ahead of the upcoming Limited Preview window

Removing hash from chunk asset name

Removing the hash from the chunk asset file name. This will allow internal and external automation to predict the file name of each asset chunk as long as the loader type and version number is known.

Bug Fixes

Final harvest does not happen when initial RUM call fails

Fixes the final harvest behavior in cases when the RUM request fails. The initial request is meant to act as a gateway for the agent to start reporting data, and its failure should result in the agent not sending anything. As of previous version, the metrics and page view timing features do not follow this rule, and that has been corrected.

September 12, 2023
Browser agent v1.240.0

v1.240.0

Features

Origin of agent webpack chunks now changeable

Allow the agent to operate through a proxy. The agent needs to be able to fetch its source code and send analytics to a different domain, and this solves the former. NPM is not affected.

Add session trace metadata params

Add first timestamp and node count information to session trace payloads for optimization in UI experiences.

Add SR to pro and spa builds (only runs for LP customers)

Add the SR feature to Pro and Pro+Spa builds of the agent. The session replay library shipping with this version of the browser agent is in limited preview and is not turned on by default. To use the feature, users will need to be part of the limited preview customer group and configure their browser application settings in the UI.

Centralize web vitals timings

Centralize web vitals timings to be accessible from any part of the agent.

September 1, 2023
Browser agent v1.239.1

v1.239.1

Features

Add best effort to detect Ajax events before instantiation

Add a "best effort" at detecting ajax events that may have happened on the page before the agent was instantiated by utilizing the ResourceTiming browser API.

Add ability for customers to wait to start harvesting. This behavior will utilize a configuration setting in tandem with an API call to trigger features to begin harvesting.

Remove allow_bfcache flag

Removes unused code which still relied on the window unload event. Going forward, the only method the agent will use to monitor potential end of page session will be visibility change in accordance with modern web practice.

Remove old supportability metrics

Removing supportability metrics that are no longer needed including polyfill detection, bfcache usage, body and query bytes sent count, and custom attributes size.

Bug Fixes

Fix issue with leaking event listeners

Fixing an issue where session timeout would result in rewrapping global event handlers. For instances where the site would be open for long periods of time, such as kiosks, this would eventually result in a degradation in event handler performance.

Issues with types resolution

Fixing issues with typescript throwing errors when trying to resolve the typings for individual features with "moduleResolution": "node" set in the tsconfig.json. "moduleResolution": "nodenext" and "moduleResolution": "node16" will enable typescript use of the exports field of our package.json but could also break other libraries and forces developers to change all local imports to include file extensions.

August 16, 2023
Browser agent v1.238.0

v1.238.0

Features

Reducing the agent chunk count

Reducing the number JavaScript files the agent loads asynchronously down to a single file. This means customer's users will now only need to load one additional JavaScript file for the New Relic Browser Agent to operate. This additional JavaScript file will continue to only be loaded upon the document "load" event. This change not only reduces the number of additional requests the agent must make but also reduces the amount of code that must be loaded by eliminating duplication.

Add API: setApplicationVersion

Add api method to top-level interface to allow the setting of application version across all outgoing payloads

Bug Fixes

Capture potential missing tail data for session trace

Send buffered session trace data in certain cases when it's being discarded at the tail end of a captured session.

Fix distributed tracing handling of empty string fetch parameter

Fixing an issue with distributed tracing that would result in an exception within the agent when fetch is called with an empty string as the first parameter.

Typo in type declarations

Fixing typos made in the browser and micro agent API declarations. This includes adding internal test cases for those types to ensure this issue does not happen again.

August 2, 2023
Browser agent v1.237.1

v1.237.1

Bug Fixes

SPA feature respects ajax deny_list for fetch

The SPA feature will now properly respect the Ajax deny list and block internal settings for fetch calls. In prior versions, the SPA feature only consulted the Ajax deny list for XMLHttpRequest calls.

prevent dollar symbol only variable names

Prevent the build process of the agent from creating minified variable names that only contain the dollar symbol. If such a variable is immediately followed by an ampersand, as could be the case in a minified logic block, it could be picked up by string replacement logic applied to outgoing HTML within their server.

Undefined deny list ignores block internal

In cases where the customer's configuration does not include the init.ajax.deny_list property, the agent would not properly account for the init.ajax.block_internal setting and would not block Ajax events for internal agent network calls.

Fix serialization issue with array data

Update the harvester to account for array payloads, which in niche cases could convert array payloads to indexed objects.

July 28, 2023
Browser agent v1.237.0

v1.237.0

Features

Stop reporting ajax events going to same beacon

Network requests made to the same hostname as the agent's reporting beacon endpoint are no longer captured, by default. As an example, outgoing XHRs to the bam.nr-data.net URL where analytic data is typically sent would not reflectively record itself.

Add warning for large payloads

Add warning for large payloads, which is typically caused by excessive custom attribute sizes.

reduce jserrors wrapping and remove onerror use

Replaces the use of the onerror global function with addEventListener to capture errors that go unhandled by customer code. This does not change how unhandled promise rejects are captured. Additional wrappings for events, timers, and animation fames have been removed in favor of capturing unhandled errors using a global event listener.

Bug Fixes

Remove fetch keep-alive unhandled rejection

Eliminate an unhandled promise rejection error caused by fetch failure in agent EoL logic.

prevent invalid error stack traces

Removing the instantiation of the Error class in the jserrors feature for instances where a non-Error value is thrown from customer's code. In such cases, an Error instance would be created and the stack trace would point back to the agent code as the source. This causes confusion since it makes it seem like the agent code is throwing the error when that is not the case. Instead, the internal UncaughtError class will be used and no stack trace will exist.

Defining agent api methods for ts types

Updating the type interface of the Agent and MicroAgent classes to properly expose the agent API methods in the generated typescript types.

Fix potential property of undefined errors

Patch a couple of areas that can yield reading property of undefined or null errors in the RUM call and jsonp wrapper.
