Title: group_id: group ids no longer allow newline characters Class: fix Compatible: incomp Component: rest-api Date: 1694774348 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 This werk addresses an issue identified by our QA team. Previously, you could include the newline character in the 'name' field when creating a contact_group, service_group or host_group via the following endpoints /domain-types/contact_group_config/collections/all /domain-types/service_group_config/collections/all /domain-types/host_group_config/collections/all We have now made pattern matching stricter, which means that this is no longer allowed.
