Full Changelog: v0.1.12...v0.2.0

v0.1.12

This release contains the following changes:

• The default trace propagation style is now "datadog, tracecontext" instead of "datadog" (#72).
• When "tracecontext" is among the configured propagation styles, the tracestate header will not be ignored in some cases where previously it would have been ignored (#72).
• The tracer now generates 128-bit trace IDs by default (#71).
• Requests made to the Datadog Agent now have a configurable timeout (#66).
• Internal telemetry sends less data on tracer startup (#68).

v0.1.11

This release contains the following changes:

• The default trace context propagation style is now "datadog" instead of "tracecontext, datadog".
• Telemetry metrics are now published to the Datadog Agent.
• The library now builds on ARM64 platforms.
• The library now builds on Darwin.

v0.1.10

This release contains the following changes:

• CURL handles can no longer leak on shutdown (#36).
• A spurious warning produced by GCC 12 no longer halts the build (#39).

v0.1.9

This release contains changes that don't affect the behavior of the library:

• CMake build changes to easier integrate with nginx-datadog, as well as some code refactoring
• new microbenchmarks under benchmark/
• a new usage example under examples/http-server/

v0.1.8

This release fixes the hard-coded release version.

v0.1.7

This release includes additional methods to the Span class and additional TraceID comparisons that will be of use in Envoy's unit tests.

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.
