Changelog and versioning

Versioning policy for the Haszno API and a dated list of changes to the public developer preview.

Versioning policy

The Haszno API is an unversioned developer preview. No version prefix exists in any path today (there is no /v1/ or similar segment).

Breaking changes may occur without prior notice during the developer preview. Do not build production integrations against this API without coordinating with the Haszno team.

When a stable version is introduced

The following contract will apply when the API moves to general availability. It is not in effect today.

  • A stable version prefix (/v1/) will be introduced.
  • A 6-month deprecation window will be honoured before removing any endpoint or response field.
  • Breaking changes will be announced in this changelog and via email to registered developers.

What counts as a breaking change

Once a stable version exists, the following are breaking changes:

  • Removing an endpoint or an HTTP method.
  • Removing a response field that was previously always present.
  • Changing the type of a response field (e.g. string to integer).
  • Changing a required request parameter to have a different type or narrower valid range.
  • Changing the meaning of an HTTP status code on a given endpoint.

The following are not breaking and may happen without notice:

  • Adding new optional response fields.
  • Adding new optional request parameters.
  • Adding new endpoints.
  • Relaxing validation (accepting values that previously returned 400).
