0020 - API backwards compatibility and versioning¶
Date¶
2025-01-24
Status¶
Proposed
Context¶
As our APIs evolve, we need a clear approach to backwards compatibility and versioning that balances stability for consumers with implementation cost.
Decision¶
We will treat breaking API changes as deliberate, versioned events and prefer additive evolution where possible.
Consequences¶
This improves consumer stability but requires stronger discipline around change management and deprecation.
