Changelog and Versioning
Track release changes, compatibility expectations, and upgrade paths for production integrations.
#Purpose
Defines how teams consume change information and maintain compatibility over time.
#Integration prerequisites
- Dependency inventory and version ownership are documented.
- Release evaluation process exists for functional and operational impact.
- Staging validation plan is ready before production upgrades.
#Request and response patterns
Version-aware clients should validate changed fields, defaults, and enum expansions before rollout.
#Lifecycle and state model
- Review changelog entries and classify changes by compatibility impact.
- Validate affected workflows in sandbox and staging against target version.
- Deploy with phased rollout and monitor key health indicators.
- Complete upgrade sign-off only after stable post-deploy reconciliation.
#Error and failure taxonomy
- Breaking contract usage from outdated client assumptions.
- Behavior drift from default value or processing-rule changes.
- Operational regressions from insufficient observability during rollout.
#Retry and idempotency guidance
During upgrade windows, preserve idempotency key semantics so retried operations remain safe across version boundaries.
#Observability and debugging entry points
- Version-tagged metrics to compare pre and post-upgrade behavior.
- Release-specific dashboards for error class and latency shifts.
- Rollback triggers tied to objective service-level thresholds.
