v1.314.0

특징

ajaxRequest.id 속성 추가

NR1 UI에서 데이터에 대한 직접 쿼리 및 드릴다운을 용이하게 하기 위해 모든 AjaxRequest 이벤트에 고유 식별자를 추가합니다.

PageViewTiming 로드 타이밍 캡처 개선

이제 웹 바이탈의 onTTFB에서 아이디어를 얻어 페이지의 로드 타이밍이 더 안정적으로 캡처됩니다. 이전에는 특히 더 크거나/더 오래 로드되는 페이지에서 브라우저 경합 조건으로 인해 nav 항목에서 loadEventEnd 이(가) 간혹 누락되어 로드가 0되는 원인이 되었습니다.

머신 절전 모드로 인한 클럭 스큐에 대해 타임스탬프 조정

특정 리눅스 및 애플 하드웨어는 절전 모드에 들어갈 때 성능 API 클럭을 멈추게 할 수 있으며, 이는 깨어날 때 뉴렐릭 이벤트에 부정확한 타임스탬프를 유발할 수 있습니다. 정지된 머신으로 인해 발생하는 클럭 스큐를 수정하기 위한 새로운 변경 사항을 도입합니다.

MFE 사용자 조치 자동 감지

data-nr-mfe-id 데이터 속성을 통한 UserAction 이벤트의 자동 마이크로 프론트엔드(MFE) 귀속에 대한 지원을 추가합니다. 이전에는, UserAction 이벤트가 컨테이너 브라우저 애플리케이션에 의해 전역적으로만 캡처되었습니다. 이 변경으로, 에이전트는 이제 data-nr-mfe-id 속성으로 식별되는 작업과 관련된 요소에 대해 상위 체인 조회를 수행합니다.

UserAction 이벤트를 등록된 MFE와 연결하려면, MFE 패키지가 제어하는 루트 DOM 노드에 register API에 제공된 ID와 일치하는 data-nr-mfe-id 을 추가하세요.

세션 리플레이가 페이로드를 재시도하도록 허용

재시도 가능한 코드로 실패한 페이로드는 에이전트에 의해 다시 수집됩니다. 수집 재시도가 성공할 때까지 추가 세션 리플레이 데이터는 수집되지 않습니다.

v1.313.0

Features

Automatically Detect MFE Errors

Add support for automatic Micro Frontend (MFE) attribution of JavaScriptError events. Previously, JavaScriptError events were only ever captured globally by the container browser application. With this change, the agent cross-compares the stack trace of the thrown Error instance 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 stack trace of the thrown Error instance, that event will be attributed to the MFE instead of the container.

remove "withCredentials"

Remove all usage of withCredentials or credentials: 'include' from agent harvests, as cookies have not been used in the agent since before v1220.

Improve MicroFrontEndTiming heuristics

Improve the ability to detect script execution times for MFE, leading to more accurate timeToLoad metrics.

Report CSP violations as new events

Content Security Policy (CSP) violations bubbled up are now captured and reported as a new SecurityPolicyViolation event type to Page Insight consumer. They become query-able through NRQL.

Apply legal and compliance requirements to register API

Ensure the register API complies to company requirements before exposing for limited preview.

Bug fixes

Bad trace.lastTimestamp in Safari + back nav edge case

Fixes a race condition where Safari browser's back navigation (BFCache) could cause absolute timestamps to be recorded at the start of the session trace feature, resulting in an abnormal trace.lastTimestamp value and a mix of relative and absolute timestamps in a single payload.

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.

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.
