v0.1.6

This release adds new features:

• W3C-style trace context propagation adds support for OpenTelemetry-compatible trace context extraction and injection. It is enabled by default, and is interoperable with Datadog-style traces.
• 128-bit trace ID generation is an opt-in feature making the tracer produce 128-bit trace IDs instead of 64-bit trace IDs. The new wider trace IDs are backward compatible with respect to Datadog-style trace context propagation.
• Additional span tags are automatically added to each span for better and more consistent reporting in the Datadog UI.

v0.1.5

This release addresses compilation portability issues revealed by Envoy's continuous integration checks.

v0.1.4

This release further experiments with conditional support for Abseil's string_view and optional, for use in Envoy builds. It addresses build issues encountered when Envoy consumed the previous v0.1.3.

v0.1.2
