Starting January 2024, Trend Micro Deep Security and Trend Cloud One™ – Workload Security Agent 20 will update to use revision version 20.0.1. The following legacy operating systems will have limited support as these have all reached their corresponding end-of-support (EOS) dates. 

• Microsoft Windows Server 2008 extended support stopped since January 14, 2020 and extended security update will stop on January 20, 2024 (Microsoft: End of support for Windows Server 2008 and Windows Server 2008 R2; Extended Security Update).
• Microsoft Windows 7 extended support stopped since January 14, 2020 and extended security update will stop on January 10, 2023 (Microsoft: Windows 7 Lifecycle Policy).
• Microsoft Windows 8.1 and Windows 8 extended support stopped since January 10, 2023 (Microsoft : Windows 8.1 lifecycle policy)
• IBM AIX 6.1 reached EOL on 30 April 2017 (IBM: AIX support lifecycle information).   
• Debian 8 reached EOL on 30 June 2020 (Debian 8 Long Term Support reaching end-of-life).

DSA 20.0.1 will not support nor provide new update releases for the above-listed platforms. The above-listed platforms will continue to have Anti-malware patterns, Intrusion Prevention, Integrity Monitoring, and Log Inspection rule updates provided using the DSA 20.0.0.#### agents until the end of extended support on December 31, 2026. For support in the Japan region, see the region-specific policy. Released DSA 20.0.0 will still work on these operating systems. For Microsoft Windows Server 2008, we understand that there are still some important workload running on this operating system, and conditional hotfixes will be provided until 2024. Starting from 2025, conditional hotfixes will only be available for Windows Server 2008 on Azure. Conditional fix includes critical vulnerability and Trend Micro defined urgent and priority bug fix. Customers who request for a fix must have the Microsoft Extended Security Update license in order to apply the security patch that enables ACS support (refer to the minimum Windows version requirement ). However, there is a risk that customers may encounter an issue which cannot be fixed by Trend Micro. At this point, the support team will work with the customer to offer acceptable alternatives. 

Moving forward, the Deep Security Agent will be revised to limit the support of the operating systems that is EOS by the OS vendor for more than one year. This process will not impact the use of minimum version for KSP usage. The announcement of revision will be published six months before the revision happens.
