+#### 0.5.0 January 1 2019 ###
+Added support for the [new B3 "single header" propagation format](https://github.com/petabridge/Petabridge.Tracing.Zipkin/issues/66), among other things.
+
+To use the new B3 "single header" format for outbound writes, you'll want to set the following property on the `ZipkinTracerOptions` class:
+
+```
+var tracer = new ZipkinTracer(new ZipkinTracerOptions(new Endpoint("AaronsAppKafka"),
+                ZipkinKafkaSpanReporter.Create(new ZipkinKafkaReportingOptions(new[] {"localhost:19092"},
+                    debugLogging: true))){ Propagator = new B3Propagator(true)  });
+```
+
+The current `B3Propagator` implementation can automatically read and deserialize inbound single header format propagation by default.
+
+
+**Other Changes**
+Petabridge.Tracing.Zipkin also introduces the following changes:
+* [Enhancement: Support for "true" value on sampling state](https://github.com/petabridge/Petabridge.Tracing.Zipkin/issues/72)
+* [Bugfix: B3 Propagation header extraction is case sensitive](https://github.com/petabridge/Petabridge.Tracing.Zipkin/issues/71)
+* [Upgraded to use Akka.NET v1.3.11](https://github.com/petabridge/Petabridge.Tracing.Zipkin/pull/74)

-You can access the Kafka reporter via the following syntax:
+    <VersionPrefix>0.5.0</VersionPrefix>
+    <PackageReleaseNotes>Added support for the [new B3 "single header" propagation format](https://github.com/petabridge/Petabridge.Tracing.Zipkin/issues/66), among other things.
+To use the new B3 "single header" format for outbound writes, you'll want to set the following property on the `ZipkinTracerOptions` class:

 var tracer = new ZipkinTracer(new ZipkinTracerOptions(new Endpoint("AaronsAppKafka"),
 ZipkinKafkaSpanReporter.Create(new ZipkinKafkaReportingOptions(new[] {"localhost:19092"},
-debugLogging: true))));
+debugLogging: true))){ Propagator = new B3Propagator(true)  });
 ```
-The `ZipkinKafkaSpanReporter.Create` method will give you the ability to specify the Kafka endpoint, topic, and batching settings used by Petabridge.Tracing.Zipkin for reporting spans back to Zipkin via a Kafka topic. Normally, however, all you'll need to specify is just a set of endpoints for Kafka brokers - both Zipkin and the Petabridge.Tracing.Zipkin client use the "zipkin" topic by default.
+The current `B3Propagator` implementation can automatically read and deserialize inbound single header format propagation by default.
