Changelog

Public-facing changelog for the Sell-Po API. Internal refactoring waves are summarised but not enumerated; only customer-visible changes are listed.

v9.x (current)

Phase F — Documentation & Operational Automation

• Week 26 — Public developer documentation site launched at developers.sell-po.co.kr.
• Week 25 — DORA metrics dashboard (Grafana) and hourly cron-driven metric computation introduced for internal operators. No public API impact.

Phase E — Observability Rollout

• OpenTelemetry SDK integration for traces, with Jaeger UI gated behind master-only RBAC.
• DORA 4-metric pilot (deployment frequency, lead time, MTTR, change failure rate) introduced as an internal capability. No public API impact.

Phase D — Modular Boundary Tightening

• Internal refactoring waves D1 through D6 completed. Public endpoint paths and OpenAPI schemas were preserved across the entire phase. No customer-visible breaking changes were introduced.

Planned

• External developer portal — self-service API key issuance and usage analytics (target: API marketplace launch).
• OpenAPI versioning — explicit v1 / v2 URL prefixes once the first breaking schema change is announced.
• SDK auto-generation — official Python and TypeScript SDKs derived from the published OpenAPI spec.
