setspaceenhanced
Makes setspace work with base font sizes beyond 10pt, 11pt and 12pt and improves its handling of font size changes inside the document.
The setspaceenhanced package was created years ago as a hack module for the
former KOMA-Script package scrhack to resolve an issue that
occurred when using setspace with base font sizes outside the
sizes supported by the standard classes (10pt, 11pt, and 12pt). In addition,
the setspaceenhanced package also handles font size changes within the
document more effectively. This enhancement can be optionally disabled.
The package is part of the “Third Party Enhancements” hosted on GitHub. Further information can be found in the CTAN catalog entry.
