Unsupported Software Findernotice of vendor support

Discourse end of life dates

The support dates the endoflife.date record (community-maintained) holds for Discourse, read on 30 Sep 2026: when security support ends for each version (cycle), when active support ends, and extended support where the record shows it. Below them, what Cyber Essentials, the Essential Eight, CIS Controls v8, PCI DSS and NIST SP 800-53 ask of a version past its end.

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that vendors still supply timely security fixes, end-of-life announcements documented, and a remediation plan for outdated technology approved by senior management.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.
