v1.313.0
Recurso
Detectar automaticamente erros do MFE
Adicionar suporte para atribuição automática de Micro Frontend (MFE) de eventos JavaScriptError. Anteriormente, os eventos JavaScriptError eram capturados apenas globalmente pelo aplicativo de navegador do contêiner. Com essa alteração, o agente compara o stack trace da instância de Error lançada com a assinatura da pilha de chamadas do módulo MFE que se registrou na API register. Se o arquivo responsável pelo registro no agente do browser for encontrado no stack trace da instância de Error lançada, esse evento será atribuído ao MFE em vez do contêiner.
remover "withCredentials"
Remova todo o uso de withCredentials ou credentials: 'include' das coletas do agente, pois os cookies não são usados no agente desde antes da v1220.
Melhorar as heurísticas de MicroFrontEndTiming
Melhorar a capacidade de detectar tempos de execução de script para MFE, resultando em métricas timeToLoad mais precisas.
Reportar violações de CSP como novos eventos
As violações de Content Security Policy (CSP) que aparecem agora são capturadas e reportadas como um novo tipo de evento SecurityPolicyViolation ao consumidor do Page insights. Eles se tornam consultáveis através do NRQL.
Aplicar requisitos legais e de conformidade à API de registro
Certifique-se de que a API de registro atenda aos requisitos da empresa antes de expô-la para visualização limitada.
Correções de bugs
trace.lastTimestamp ruim no Safari + caso extremo de navegação de retorno
Corrige uma condição de corrida em que a navegação de voltar do navegador Safari (BFCache) poderia fazer com que um timestamp absoluto fosse registrado no início do recurso de trace da sessão, resultando em um valor trace.lastTimestamp anormal e uma mistura de timestamp relativo e absoluto em uma única carga.
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.

v1.312.0
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.

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.

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.
Removing old SPA feature & related wrappings entirely
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

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

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
