v1.0.0

This is the first stable release of the Splunk Distribution of OpenTelemetry Go which is compliant with Splunk's GDI Specification v1.3.0.

Please note that although the distribution is marked as stable, some of its dependent components (e.g. otelhttp instrumentation library)
are still experimental.

This release uses OpenTelemetry Go v1.7.0 and OpenTelemetry Go Contrib v1.7.0/v0.32.0.

v0.9.0

This release contains configuration fixes and simplifies the API before a stable release is published.

v0.8.0

Added

• Add the WithPropagator option to github.com/signalfx/splunk-otel-go/distro along with parsing of the OTEL_PROPAGATORS environment variable to set the global OpenTelemetry TextMapPropagator. (#295)
