Release v1.35.0/v0.60.0/v0.29.0/v0.15.0/v0.10.0/v0.8.0/v0.7.0

[XSAM]

Overview

This release is the last to support Go 1.22.
The next release will require at least Go 1.23.

Warning

This is the last version to use Semantic Conventions v1.20.0 for HTTP libraries
by default. The next version (0.61.0) will default to v1.26.0, and the
following one (0.62.0) will drop support for Semantic Conventions v1.20.0

You can switch to the new Semantic Conventions right now by setting the
OTEL_SEMCONV_STABILITY_OPT_IN=http/dup environment variable in your
application.

migration
