Summary
With the release of Go 1.21, this dd-trace-go release drops support for Go version 1.18 and older, following our Go support policy. This minimum supported Go version for this library is now Go 1.19.
This release adds the contrib/IBM/sarama package to support for tracing the IBM/sarama Kafka library.
The Data Streams Monitoring Go library has been incorporated into this library. The feature can be enabled by setting the DD_DATA_STREAMS_ENABLED environment variable to true.
This release introduces a debug mode for the tracer to help identify long-lived or abandoned spans, which can lead to increased memory usage. It can be enabled with the WithDebugSpansMode(true) tracer option or by setting enviornment variable DD_TRACE_DEBUG_OPEN_SPANS=true.
This release also includes several bug fixes and performance improvements:
- Fix a bug in
contrib/database/sqlwhich incorrectly cached contexts. - Resolve a data race in
contrib/net/http. - Reduce the memory allocated during initialization of the
contrib/google.golang.org/apipackage. - Improve the latency of W3C traceparent header validation.
