Potential Breaking Changes (from @microsoft/applicationinsights-web v3.4.1)

This release bumps the Application Insights dependency from ^3.3.10 to ^3.4.1. The 3.4.x release of Application Insights includes significant changes that may affect your application. Please review the following before upgrading.

This version is NOT supported on any eariler versions of Application Insights.

Package Deprecation

The following packages have been merged into @microsoft/applicationinsights-core-js and are now deprecated. They continue to be published as backward-compatible shims (re-exporting from Core) so existing code will not break, but you should migrate to importing from @microsoft/applicationinsights-core-js directly:

• @microsoft/applicationinsights-common — All exports have been merged into @microsoft/applicationinsights-core-js. The package is now a compatibility shim. See the Migration Guide for details. This package will be removed in a future major release (4.0.0).
• @microsoft/1ds-core-js — All exports have been merged into @microsoft/applicationinsights-core-js. See the 1DS Core Migration Guide for migration steps. This package will be removed in a future major release (4.0.0).

Interface Changes

• The IDistributedTraceContext interface has been significantly expanded to include W3C trace state management capabilities, which may affect custom telemetry processors that interact with distributed tracing context.
• The TelemetryTrace class has been removed. The telemetryTrace property is now an adapter to the existing core.getTraceCtx() value and is marked as deprecated.
• The internal ajaxRecord class has been removed from @microsoft/applicationinsights-dependencies-js and replaced with the IAjaxRecordData interface.
• The flush method parameter was renamed from async to isAsync in the IChannelControls interface.

Significant New Features in Application Insights 3.4.1

• W3C Trace State support with new distributed tracing modes (AI_AND_W3C_TRACE, W3C_TRACE)
• OpenTelemetry integration preparation with foundational interfaces
• Enhanced cookie management with in-memory caching when cookies are disabled

For full details see the Application Insights JS 3.4.1 release notes.
