Browser agent release notesRSS

v1.292.0

Features

Update BrowserInteraction and previousUrl definition

Update BrowserInteractions to use document.referrer for previousUrl values on initialPageLoad interactions instead of mirroring previousUrl and targetUrl. This enables better functionality for user journeys and provides more insight on page linkages.

Add more inspection events

Adds new inspection events to the agent. These events include the drain event, window lifecycle events such as navigate, load, DOMContentLoaded, and the session event which emits on changes to the agent's session state.

Bug fixes

Fix finished API timeSinceLoad value

Fixes an issue where the finished api was creating a timeSinceLoad value for PageAction data as the unix timestamp instead of a relative time value in seconds from the page origin.

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.

Consistent with our browser support policy, v1.292.0 of the Browser agent was built for and tested against these browsers and version ranges: Chrome 127-137, Edge 127-137, Safari 17-18, and Firefox 128-138. For mobile devices, v1.292.0 was built and tested for Android OS 16 and iOS Safari 17-18.1.

v1.291.1

Bug fixes

Prevent ST from holding onto Event refs in memory when aborted

Releases the Event entries the agent hold onto in Trace after it has aborted. This addresses a known case of memory leak caused by continuing to add those references to a Set that is never cleared.

Clean BrowserPerformance entryName for resources

The entryName attribute of resource type BrowserPerformance events will now have a cleaner URL, removing the hash fragment from reported URLs.

Add safeguards for addToTrace

Events created with addToTrace API, which have an invalid UNIX timestamp, emit a warning and return without creating the event.

v1.291.0

Features

Create the measure API

Adds the measure API to the newrelic global object. This API allows generating new BrowserPerformance data even if auto-detection of marks and measures is not enabled.

Bug fixes

Fix race between end of session and features aborting

Fix an issue where features would race with the session manager when a session ends. This required a check for session timings to match a given session and could create a state where a new session created from a pre-existing session would trigger a partial replay or no replay, and prevent the agent from sending trace data with a given replay.

Harvest first session trace payload immediately

For better consistency, implemented old behavior where the first ST payload is harvested immediately when the page loads. This helps ensure cases where replays are harvested but traces are not happen less frequently.

Declaração de apoio

New Relic recomenda que você atualize o agente regularmente para garantir que esteja obtendo os benefícios mais recentes de recursos e desempenho. Versões mais antigas não terão mais suporte quando chegarem ao fim de sua vida útil. As datas de lançamento refletem a data de publicação original da versão do agente.

Novos lançamentos de agente do browser são disponibilizados aos clientes em pequenas etapas ao longo de um período de tempo. Por esse motivo, a data em que o lançamento fica acessível à sua conta pode não corresponder à data de publicação original. Consulte este dashboard de status para obter mais informações.

v1.290.0

Features

Bundler tools exports

An optional Webpack splitChunks cacheGroup matcher is now available for users who build the agent via NPM. This matcher enables de-duplication and merging of the agent's lazy-loaded JavaScript into a single chunk. This single chunk loads post-page render, consistent with the behavior of our pre-built agent for APM and copy/paste implementations.

Set UserAction currentUrl before aggregation end

Set currentUrl on the first event of a user action instead of at the end of aggregation.

Improve lazy-loading optimization

Optimize our pattern to ensure that code-bundlers such as webpack can more effectively tree-shake the output to only include the relevant files needed to run the agent. This specifically helps reduce the bundle size, reduce the amount of lazy files generated, and streamlines "custom" agent builds used with NPM.

API Code Splitting

Split the API method definitions per feature instead of a single file shared across all loader types. This allows each loader to only instantiate the necessary APIs for the features included, and reduce overall bundle size for the "Lite" build as well as custom-built agents with NPM. A shell will still exist for non-initialized APIs to prevent errors from throwing on APIs used without the needed features.
