First off - excellent product and appreciate the community effort to keep ClosedXML alive and well.
As time goes by, the dependency on list and sub dependencies needs to be clearer and if at all possible, up to date.
As security tightens and old libraries get flagged would it be possible to maintain a complete list of direct and sub dependencies?
Also, is full support for .NET 8/9 in place and tested? Currently on Framework 4.8 which has proven to be very problematic.
