# Changelog

> Material changes to The Data City API, newest first.

This page records material changes to the v2 API — new endpoints, new fields, breaking changes, and behaviour shifts worth knowing about.

<Note>
  The Data City does not maintain a separate API changelog today. This page is the new canonical home; entries will accrue here as the v2 API evolves. For a precise record of past changes between two points in time, diff the OpenAPI spec at [`/api/documentation/spec/v2`](https://product-api.thedatacity.com/api/documentation/spec/v2).
</Note>

## Conventions

Entries are tagged so you can scan for the kind of change that affects you:

* **Added** — new endpoint, field, or capability. Safe to ignore if you don't use it.
* **Changed** — non-breaking change to existing behaviour (new optional field, tightened error message, performance improvement).
* **Deprecated** — still works but scheduled for removal. Start migrating.
* **Removed** — no longer available. Will only appear in a major version bump.
* **Fixed** — bug fix bringing actual behaviour in line with documented behaviour.
