Issue/Introduction

In the process of upgrading XCOM on distributed platforms to ensure all have a minimum of TLS 1.2 support.
Please advise on the lowest/earliest XCOM version for each distributed platform that supports TLS 1.2.

Resolution

XCOM versions on distributed OS platforms are either 11, 11.6 or 12.0.
Version 12.0 is only for Linux and Windows. They are more recent and by default support TLS 1.2.
Therefore the information below covers the earlier 11.* versions.

However, 11.6 SP01 for Windows has already reached End Of Service over 1 year ago on 31-Oct-2022.
