KKTeX submitted an update to the
modernruler
package.
Version number: 1.1.0 2026-01-06 License type: mit
Summary description: Flexible ruler and annotation commands with key-value support and vertical writing compatibility
Announcement text: ----------------------------------------------------------------------
Updated the package to address the issue reported in https://github.com/KKTeX/modernruler/issues/1.
Previously, \zw was used internally, which caused compatibility issues in certain LaTeX environments. Since \zw is specific to Japanese typesetting, it has been replaced with em for Latin text environments (as they are functionally equivalent) to ensure broader compatibility.
