New version 4.0 was introduced. 4.0 introduces several changes to API parameters and responses that are not compatible with their counterparts of earlier versions
Adaptations for the search endpoint:
-- The response was adapted to by default only return basic data for found elements. Additional data (e.g. attributes, relations, other data) has to be explicitly specified.
-- To specify additional data to be contained in the response (rwf information, links, stableLink, etc.), the URL parameter include has to be used.
-- Paging is now enforced and page sizes can not be larger than 1000 elements.
-- The new include parameters allAttributes and allRelations (e.g. ?include=allAttributes&include=allRelations) can now be used to explicitly return all attributes and/or all relations for elements in the search result. This should be used with care as this can result in very large results.
