v1.67.0

Summary

In this release, Application Performance Monitoring (APM) introduces optimized W3C context propagation, reduced lock contention on Git metadata tags and support for span events in OpenTelemetry. It improves multiple contribs, see below, and releases a new one for uptrace/bun. It also introduces multiple fixes, improves support for Orchestrion and deprecates hostname detection, now available behind a compatibility environment variable DD_TRACE_CLIENT_HOSTNAME_COMPAT=v1.66.0.

Contribs updated in this release:

• gocql/gocql: support for MapScanCAS and the Observer API, and bug fixed in cluster and datacenter tag values, old behaviour available behind compatibility environment variable DD_TRACE_GOCQL_COMPAT=v1.65.
• gorm.io/gorm.v1: adds parent span propagation.
• IBM/sarama.v1: support for DSM.
• net/http: support for rwUnwrapper interface.
• uptrace/bun: new contrib available.

Application Security Management (ASM) improves WAF run operations and upgrades go-libddwaf.
