Attendee edits are now checked more thoroughly across both the public forms and the API, helping prevent bad or inconsistent data from making it into your event records.
Why it matters: cleaner attendee data means fewer surprises at check-in, more reliable communications, and less time spent hunting down and correcting errors after the fact. Organizers and integrators can trust that updates coming through any channel meet the same quality standards.
- Added validation rules to the Attendee model to catch invalid changes before they are saved
- Extended the same validation coverage to the API v3 endpoints (attendees and attendee workshops) so third-party integrations follow the same rules
- Applied consistent checks in the public attendees controller for self-service edits
- Localized validation messages across all supported languages
