API changelog
This page documents changes to the Zulip Server API over time. See also the Zulip release lifecycle for background on why this API changelog is important, and the Zulip server changelog.
The API feature levels system used in this changelog is designed to make it possible to write API clients, such as the Zulip mobile and terminal apps, that work with a wide range of Zulip server versions. Every change to the Zulip API is recorded briefly here and with full details in Changes entries in the API documentation for the modified endpoint(s).
When using an API endpoint whose behavior has changed, Zulip API
clients should check the zulip_feature_level
field, present in the
GET /server_settings
and POST /register
responses, to determine the API
format used by the Zulip server that they are interacting with.

operator. Theis:dm
filter replaces and deprecates theis:private
