The text announces the release of the OpenAPI 3.1 Cheat Sheet, a concise and comprehensive guide designed to aid the community in effectively using OpenAPI by providing a hand-held reference. After six months of development, involving collaboration with OpenAPI experts and key users, the Cheat Sheet condenses the complex OpenAPI Specification into manageable sections such as Document Structure, API Structure, and Security. The resource is freely available under a CC BY-NC-SA 4.0 license and is intended to be accessible in both printed and PDF formats. The creators plan to continue refining this version, addressing any errors identified, and expanding its scope to include future OpenAPI versions and a web version. They encourage sharing the guide widely to benefit the entire OpenAPI community.
