I happened to read the fine print in the WPM release notes (here) and it shows:
SolarWinds End of Life Policy
SolarWinds Orion WPM 2.1 has entered the End-Of-Life (EOL) cycle. This means that SolarWinds will no longer provide any form of support (such as covering call, engineering updates, etc.) for Orion WPM version 2.1 or older. See the SolarWinds EOL Policy online for more information. See the SolarWinds EOL Policy online for more information.
As v2.2 was just released a week ago, it seems a little aggressive to no longer support the previous version.
Can I assume this is a misprint? Would someone from SolarWinds be so kind as to update this to reflect when v2.1 will no longer be supported?
