Release notes

Resolve the range

Read repository release conventions and determine the version, audience, and exact from_ref..to_ref range.
Derive the previous release from reachable tags when unambiguous. Ask before proceeding if multiple release lines or an unknown target make the range materially ambiguous.
Verify both refs and record their SHAs. Do not use a date window when an exact range is available.

Use first-parent history to identify release-sized changes, then inspect the full commit list and diff so squash, rebase, and direct commits are not missed.
Prefer the repository connector for linked PR and issue metadata; use the hosting CLI or local Git as fallback.
Read relevant diffs for configuration, API, schema, migration, dependency, runtime, deployment, and security changes. Do not infer impact from titles alone.
Separate user-visible changes from internal maintenance and omit noise that does not help the target audience.
