# API changelog

> Date-versioned changes to the Onlyform Public API.

The Onlyform API uses `YYYY-MM-DD` contract versions. The current version is `2026-08-01`, matching `info.version` in the OpenAPI document.

<Note>
  The date currently identifies the deployed contract and is not a request header. Onlyform does not yet offer per-account version pinning.
</Note>

## Versioning policy

* Additive changes, documentation corrections, and compatible fixes may ship without changing existing request behavior.
* A breaking contract change receives a new date version and a dedicated changelog entry with migration instructions.
* Deprecated behavior is announced before removal when security or legal requirements do not require an immediate change.
* SDK releases use semantic versions and document which API date they target.
