Browser agent v1.256.0

v1.256.0

Features

Generate PTID in Agent

Generate PTID in agent instead of in RUM response. This allows PageView events to be decorated with a page trace ID.

Allow unmasking elements with nr-unmask selectors

Add custom masking mechanism to allow unmasking elements with nr-unmask class selectors and data-nr-unmask data attribute selectors

Adjust Session Replay Error Tracking

Adjust when errors are decorated with session replay identifiers to more closely match actual recording data

Bug fixes

stabilize timestamp corrections

Ensure Session Replay timestamps are only ever adjusted once and fix correction factor to alleviate timeOrigin inconsistencies

Resume Page Focus Now Checks Session State

Check session state when resuming focus to an actively instrumented page. This ensures that stale sessions are caught before invoking other feature-level methods.

Browser agent v1.255.0

v1.255.0

Features

Adjust session replay timestamps to New Relic server time

Adjust all timestamps sent as session replay event nodes to represent New Relic server time for accuracy in querying against adjacent but separate events in the timeline such as errors, page views, and interactions.

Send CLS as timing node additionally

cumulativeLayoutShift can now be queried for (with that as its timingName) as its own PageViewTiming event in New Relic. The additional attribution are a part of these events, and the values are more reflective of true end-session CLS scores.

Update agent to use new relic server time

Update the agent to use New Relic server time as the timestamp for harvested page action and error data.

Switch web vitals library to attribution build

Report extra attributes for each vital using web vital library's attribution build.

Browser agent v1.254.1

v1.254.1

Bug fixes

Server Timing - Remove reliance on performance API

Removing reliance on the browser resources API for the calculation of New Relic server time. On site with many resource requests, there was a small chance that the RUM network call would be flushed from the resources API cache before we could capture it and calculate server time.

Browser agent v1.254.0

v1.254.0

Features

Standardize all feature behavior to wait for RUM response

Force features to wait for entitlement checks from the rum call before processing buffered data.

maintain a harvestCount for use later with harvestId

Add a counter which increments after every harvest. This will be used in a future effort to curate a unique harvest ID for API paging purposes.

Add rum-response metadata handler

The initial connect call can now supply browser app metadata. This adds a handler to store and use that metadata for future harvests.

Calculate New Relic time in the agent

Migrating the process of time-stamping harvested data to the agent. The agent uses the date and time reported by the ingest pipeline during the RUM call as well as browser network and timing stats to derive a server time offset that can be applied to harvested data as event occur. This improves the ability to visualize the harvested data on a timeline within the New Relic UI.

Bug fixes

Remove webpack imports in npm package

Transitioning certain module imports so that the default import is for the npm version of the module instead of the cdn or webpack version. This should completely eliminate all references to webpack globals when using the npm package.

March 13
Browser agent v1.253.0

v1.253.0

Features

Soft Navigations trial

Introducing a lighter and simplified version of the existing spa feature that tracks soft navigations. This new feature still sends BrowserInteraction events, but the duration and finishing of those interactions have been redefined. As a replacement, it ought to reduce complexity and integration issues around the existing spa and exhibit better and faster performance.

Apply deny list to ajax metrics

The ajax deny list has historically only applied to the collection of ajax events and not ajax metrics. With this feature, the deny list will also be applied to the collection and reporting of ajax timeslice metric data. If an ajax request matches an entry in the deny list, both events and metrics will be blocked from being collected in the agent. This feature will be behind a feature flag to assess impact before final complete rollout. Thanks to community member @Wrhector for contributing this feature.

Preload the session replay recorder when properly configured

Load the session replay recorder module before the page load when configured to do so. This will increase visibility for recordable data for customers who have opted in to the behavior.

Isolate observation context per agent

Initial implementation of an isolated observation context per agent running on the same page. This reduces the modification of instances of globals like events and instead each agent will track its own observation context internally.

Browser agent v1.252.1

v1.252.1

Bug fixes

Fix webpack imports in npm package

Fixing some import overrides in our NPM package build to prevent imports existing that include code reliant on webpack globals. This will resolve the error Uncaught ReferenceError: __webpack_require__ is not defined when using the NPM package in a project that does not use webpack.

Page load after session timeouts don't start new session

When a session expires or becomes inactive while the user does not have the page open and they re-open the page, that is now treated as a new session.

Browser agent v1.252.0

v1.252.0

Features

Add types mappings for esm distribution

Adding typescript types mappings for the ESM distribution in the npm package.

Report config changes away from default state for UX improvement

Detect if the default config values have been altered at runtime. This is useful to evaluate what the reasonable defaults are across a customer base over time to provide a better UX.

Create more granular metrics about stylesheet fix success

Utilize a finer granularity when collecting success metrics on local stylesheet fixes for Session Replay compatibility.

Align browser reported uncaught syntax errors

Aligning the data reported for uncaught syntax errors across modern browsers. Chrome specifically fails to include the file name and line number in instances of SyntaxError. This could also cause issue in the New Relic error inbox where Chrome syntax errors were not being properly grouped.

Capture Internal Metrics for Session Replay Configurations

Capture supportability metrics sounding Session Replay configuration usage to improve user experiences around configuration of the agent's Session Replay feature.

Bug fixes

Add safe logic to snapshots

Safe-guarded a race condition where an asynchronous call to fix a stylesheet could trigger the agent to try to force a snapshot after it has already stopped recording due to a visibility change.

Fix adblock memory leak

Fixed memory leaks caused by request resolve failure (e.G. due to adblocker). Thanks to community member @Joe-Degler for contributing this fix.
