            You are writing release notes for ABP Studio documentation.

            Existing format example:
            ${{ steps.format.outputs.FORMAT }}

            Release info:
            Version: ${{ github.event.client_payload.version }}
            Name: ${{ github.event.client_payload.name }}
            Raw notes:
            ${{ github.event.client_payload.notes }}

            Instructions:
            - Extract only meaningful user-facing changes
            - Use bullet points starting with "- "
            - Be concise and professional
            - Return ONLY bullet points
