A version this table does not list is not in the record: the finder reads it as unknown, never supported. The dates are the record's own; nothing here states a date the record does not hold.

What the schemes ask of a version past its end

Cyber Essentials
software on in-scope devices licensed and supported by the vendor, meaning it still receives security updates; unsupported software removed or segregated (SU.1, SU.4). Cyber Essentials Plus: removed, or isolated with compensating controls (PM-02).
Essential Eight
An application outside the priority classes: Patch applications asks for its removal once no longer supported at ML3; at ML1 and ML2 no held Essential Eight clause turns on it.
CIS Controls v8, Safeguard 2.2
only software that still receives vendor support may be marked authorised; unsupported software kept for the mission needs a recorded exception with compensating controls and the acceptance of the remaining risk; support status checked at least monthly.
PCI DSS 12.3.4
hardware and software reviewed at least every 12 months: that vendors still supply timely security fixes, end-of-life announcements documented, and a remediation plan for outdated technology approved by senior management.
NIST SP 800-53 SA-22
system components replaced when support is no longer available from the developer, vendor or manufacturer, or alternative sources of continued support provided.
