Summary

Regenerates the TypeScript, Java, and C# SDKs from the updated public spec for the October 7-8, 2026 release. Adds 9 new API endpoints (List Attendee Optional Items and the Venue Attractions CRUD + image endpoints), along with updates to the Budget, Seating, Sessions, Venue Content, Venue Meeting Rooms and Venue Profiles APIs.

Changes

• Updated the public OpenAPI spec (+1462/−840)
• Regenerated the TypeScript, Java, and C# SDKs via Speakeasy (release version 1.6.4)
• New methods: attendees.listOptionalItems; venueContent.listVenueAttractions, createVenueAttraction, getVenueAttraction, updateVenueAttraction, deleteVenueAttraction, associateAttractionImage, getAttractionImages, disassociateAttractionImage
• New models: VenueAttraction, ExistingVenueAttraction, AttractionImage*, PaginatedOptionalItem, DonationItem, MembershipItem, and more
• Breaking rename: the full event model Event1 is now Event11 (return type of getEventById/updateEvent, item type of EventPaginatedResponse). Event1 is now the id-only model used by AccountBudgetItemListResponse.event
• Other renames: *Json-suffixed models cleaned up (e.g. ExpandableSeatJson → ExpandableSeat, HookSecurityJson → HookSecurity); Rfp → Rfp1/Rfp2; QuantityItem → QuantityItem1/QuantityItem2; BudgetVersionId replaced by BudgetVersion
