`2026-10` is now the current API version

API version 2026-10 became the current version on October 26, 2026. 2026-07 moves to maintenance, and 2027-01 is the release candidate.

Only callers that do not send an API-Version header are affected: they now get 2026-10. Requests that pass a version name keep using that version, so nothing changes for them. We recommend passing a version name in every request so that you decide when to move.

2026-10 includes breaking changes, among them the removal of deprecated fields on the User type and several Workforms removals. Read the 2026-10 release notes and the User entity migration guide before you move to it. See API versioning for how version types and the version schedule work.
