Release notes from DataDog/dd-trace-go v1.74.0:

This is the last minor release for v1. The Go tracer v1 transitional version is a wrapper that preserves the API from v1 but uses v2 under the hood.

This transitional version is the only v1 version that allows both v1 and v2 to be imported in the same service—enabling you to migrate a service gradually. Using this v1 transitional version doesn’t require any code changes, but it also won’t support any new features introduced in the new v2 tracer.

Note that, while we are offering the v1 transitional version for the convenience of our customers, we strongly encourage you to upgrade to the v2 version as soon as possible to benefit from the newest features and improvements. If you have concerns or reasons to not upgrade to the transitional version, contact us and we’ll work together to resolve them

CoreDNS was updated to use v1.74.0 in #7368.

Why is this needed:

Upgrade to v2 is required as v1 will be deprecated by the end of 2025. See docs here. Migration guide is available here.
