api_version, a date. All destinations start on 2026-10-01.
What is not a new version
TIKT can, at any time and without notice:- add a field to an object;
- add an event type — a destination listening to All events receives it;
- add a value to a field that has a list of values (a new
status, a newreason).
What is a new version
Removing a field, renaming it, or changing its type is a new version:- announced six months in advance;
- never imposed on a version in use: each destination keeps its version until its owner changes it.
