Retired versions of CloverDX products are still supported. That means you're still eligible for raising support tickets if you have paid for maintenance. You can do it either via our CloverCARE Support portal or via an email to email@example.com. However, retired versions are not maintained by our development team, which means there are no new bugfixes provided for these versions.
EOL (End-of-Life) versions of the CloverDX product are not supported, neither are they bugfixed. You can find more information on our website: https://support.cloverdx.com/releases/
In both cases, it is highly recommended to upgrade to a maintained version of the CloverDX product.
