@kamphaus looks fine now.. did you change anything? 🤔

[kamphaus]

The merge queue runs checks after merging into main.
It looks like the policy changes from #3752 are blocking.

This work fails on the CI policies-check, see here. There are 3 attributes used by process metrics that have a stability of development:

Diagnostic report:

I am going to open a separate PR to mark these attributes as release candidate.

PR opened to Promote the above attributes to RC: #3796

[trask]

Looks like this is failing a recently added policy check that stability level on the group must be the same or higher than all non opt-in attributes.

Looks like this is failing a recently added policy check that stability level on the group must be the same or higher than all non opt-in attributes.

I have merged from main, all checks now pass, we merged the PR #3796 which promoted the required attributes to RC which was blocking here.

@open-telemetry/specs-semconv-maintainers this work is now unblocked and good to be merged.
