 ## [Unreleased]
 
+* [API] Jaeger Propagator should not be deprecated
+  [#3086](https://github.com/open-telemetry/opentelemetry-cpp/pull/3086)
+
+Important changes:
+
+* [API] Jaeger Propagator should not be deprecated
+  [#3086](https://github.com/open-telemetry/opentelemetry-cpp/pull/3086)
+
+  * Deprecation of the Jaeger propagator, as announced on 2023-01-31
+    in version 1.8.2, is now reverted.
+  * This deprecation turned out to be not justified,
+    as the Jaeger propagator can be used without the (now removed)
+    Jaeger exporter.

-### Jaeger propagator
-
-#### Announcement (Jaeger)
-
-* Version: 1.8.2
-* Date: 2023-01-31
-* PR: [DEPRECATION] Deprecate the Jaeger exporter
-  [#1923](https://github.com/open-telemetry/opentelemetry-cpp/pull/1923)
-
-This PR also listed the Jaeger propagator as deprecated.
-
-#### Motivation (Jaeger)
-
-The Jaeger Exporter is now (July 2023) removed from the OpenTelemetry specification.
-
-The Jaeger Propagator remains, because changing propagation is a longer
-process compared to changing an export format.
-
-New deployments however are encouraged to use a W3C compliant propagator,
-and avoid the Jaeger propagator, which is now deprecated.
-
-#### Scope (Jaeger)
-
-The following are deprecated and planned for removal:
-
-* the API header `opentelemetry/trace/propagation/jaeger.h`, including:
-  * the C++ class `JaegerPropagator`
-
-#### Mitigation (Jaeger)
-
-Use a W3C compliant propagator instead.
-
-That is, use class HttpTraceContext and "traceparent" tags.
-
-Do not use class JaegerPropagator and "uber-trace-id" tags.
-
-#### Planned removal (Jaeger)
-
-No date set yet for the Jaeger Propagator.
