Kong Gateway Enterprise 3.1.x.x will transition out of Full Support by December 2023 and enter a Sunset Support phase until December 2024, according to the company's support policy. During this Sunset Support phase, Kong will offer limited assistance to help customers upgrade to a fully supported version but will not issue patches for this version. Customers are advised to upgrade to a supported version, with the recommendation to move to the latest Long-Term Support (LTS) version, which is 3.4.x.x, if they cannot consistently upgrade within a 12-month period.
