@inge4pres We have launched our new documentation website and now have the ability to easily add release notes for Profiling.

Here's the new Obs release page: https://www.elastic.co/docs/release-notes/observability.

What repository would you like the release notes to be set up in?

I will then:

• Add the files in this dir to that repo: https://github.com/elastic/apm-server/tree/main/docs/release-notes
• Add our build ci to that repo: https://github.com/elastic/apm-server/blob/main/.github/workflows/docs-build.yml
• Add repo to https://github.com/elastic/docs-builder/blob/main/src/docs-assembler/assembler.yml
• Add repo to https://github.com/elastic/docs-infra/blob/main/modules/aws-github-actions-oidc-roles/repositories.yml
