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.

v1.291.1

Corrección de errores

Evitar que ST conserve referencias de eventos en la memoria cuando se aborta

Libera las entradas Event que el agente mantiene en traza luego de abortar. Esto soluciona un caso conocido de pérdida de memoria causada por continuar agregando esas referencias a un conjunto que nunca se borra.

Limpiar BrowserPerformance entryName para recursos

El atributo entryName del evento de tipo de recurso BrowserPerformance ahora tendrá una URL más limpia, eliminando el fragmento hash de las URL informadas.

Agregar salvaguardas para addToTrace

Los eventos creados con API addToTrace, que tienen una timestamp UNIX no válida, emiten una advertencia y regresan sin crear el evento.

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.

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.
