EPPlus major versions target specific .NET runtime versions. The support period for each major version is tied to the lifecycle of its targeted .NET runtimes. Maintaining a library on an end-of-life runtime would reduce security rather than improve it. Security patches released during the support period remain available via NuGet for at least 10 years.
