RUM JS Agent version 5.x

RUM JS Agent version 5.x

5.16.1 (2024-06-27)

Bug fixes

User interaction click transactions will report correct transaction names for IE11 #1511

5.16.0 (2023-12-27)

Features

Add Support for Interaction to Next Paint (INP) metric. This new metric, which replaces FID, will be available in the User Experience App from version 8.12.0 of the Elastic Stack. #1462

5.15.0 (2023-09-27)

Potentially breaking changes

Previously, there was a start time discrepancy between sampled and unsampled page load transactions, which was wrong. From now on, the agent will set the same start time for both of them.

Custom dashboards built using the page load duration will see an effect with the solution: #1435

Features

Capture errors from objects thrown from the promise rejection events including the reason and custom properties: #1428

5.14.0 (2023-08-03)

Features

Add redirect span to the page-load transaction: #1400

Bug fixes

Fetch API instrumentation now handles requests with URL objects. #1398

5.13.0 (2023-07-19)

Potentially breaking changes

Previously, breakdown timings were reported as milliseconds values in the span.self_time.sum.us field, which was wrong. From now on, it will be reported as microsecond values to match the APM specification: #1381
The metrics transaction.duration.sum.us, transaction.duration.count and transaction.breakdown.count are no longer recorded: #1382

Features

Support for Angular 16 is made available via @elastic/apm-rum-angular@3.0.0: #1380
Improve user-interaction transactions naming. Unsupported browsers: IE11 #1390
Add apmRequest and sendCredentials config to TypeScript typings: #1254 #1243

Bug fixes

Fix warnings where performance entries are not supported: #1246

5.12.0 (2022-06-14)

Features

Introduce new config option sendCredentials. This allows the agent to send cookies to APM servers that are behind reverse proxies that need requests to be authenticated: #1238
Agent now warns users if they provide non-existent config options when initializing it: #1230

Bug fixes

Capture the stacktrace of a SyntaxError triggered because of a malformed JavaScript code. Before this fix the agent was capturing an empty stacktrace: #1239

5.11.1 (2022-05-16)

Features

Span’s outcome is now set to Unknown when a Fetch/XHR request is aborted. The outcome can be found in the metadata information of the span details in APM UI: #1211
Allow users the ability to disable compression for the events sent to APM server. This is helpful for debugging purposes while inspecting via Devtools and also for generating HAR file. Please see our troubleshooting guide for more information: #1214

Bug fixes

The instrumentation of fetch API consumes a response as a readable stream properly. Before this fix the related span was being ended on the start of the response rather than on the end of it: #1213
Agent now can listen to all click events on the page. Users can enable/disable click instrumentation via disableInstrumentation: ["click"]. eventtarget instrumentation flag will be deprecated in favor of click and will be removed in the future releases: #1219

5.11.0 (2022-04-20)

Features

Events are now beaconed when the user abandons or backgrounds the page, this makes sure the agent never miss an event. Before this change it was only sending them every interval configurable via flushInterval. Unsupported browsers: Firefox, IE11: #1146

Transactions based on the supported technologies and custom managed transactions are the only ones taken into account.

rum-vue: Introduce script setup syntax support: #1194
Override reuse threshold when redefining a transaction. This will permit the agent not to miss data on slow network connections: #1196

5.10.2 (2022-02-03)

Bug fixes

create user-interaction transactions based on the element on which the event occurred rather than the element on which the event handler has been attached. All web applications that rely on event delegation will benefit from this: #969

5.7.1 (2021-03-17)

Bug fixes

Discard buffered longtasks spans from page load transactions getting added to subsequent route change and other auto auto-instrumented transactions resulting in incorrect start time for those transactions: #989
