Strapi beta.19 introduces the Single Types feature, a highly requested addition that facilitates management of unique, non-repetitive content such as menus, static pages, and footers. Single Types allow users to create and manage content that will only have one instance, unlike Collection Types which are used for content that is repeated. The feature is particularly useful for global settings and SEO, incorporating a UID field to ensure unique, SEO-friendly URLs. Users can easily create Single Types through the Content-Type Builder and modify the content author experience by configuring the view and order of fields. Single Types can have one-to-one or one-to-many relations with Collection Types, and they can be converted to Collection Types and vice versa, provided relational compatibility is maintained. The update also includes contributions from community members, and Strapi encourages ongoing user engagement and contributions to its open-source platform.
