An operating system release is considered "supported" if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve security issues discovered in the system software.
The version is still partially supported but has been superseded and must be removed from the enclave network or upgraded to a supported version.
Premier Support (full patches and updates) ended on December 31, 2024. Extended Support (critical security fixes only) continues through June 30, 2028.
