Changelog · Nowgate docs

An API version is a date, and 2026-11-01 is the only one. Every event names the version its body follows, in api_version.

A new version comes only with a breaking change: removing or renaming an operation, a field or an event type, a new required field, changing a field's type or meaning, or refusing a request that was valid. /v1 never breaks in place.
Compatible changes land in place, dated below under the version they extend: new operations, new optional fields in requests, new fields in responses, new event types, new values of an enum, new error codes, and new networks and assets. Accept what you don't know, as the SDKs do.

Each SDK follows semantic versioning, names the API version it was made for, and keeps its own changelog beside its code.
