Accepted, maintainer-reviewed milestones in the history of OpenTelemetry semantic conventions. Candidates that have not been reviewed are never listed here.

**Machine-readable**: [/data/semantic-conventions/accepted-history.json](/data/semantic-conventions/accepted-history.json)

Release keys are source-qualified (`{source}@{tag}`) because two repositories can publish the same tag.
