+@code{amsmath} and @code{mathtools} packages to be more compatible with the
+LuaTeX engine.  It is only meaningful for LuaLaTeX documents containing
+mathematical formulas, and does not exhibit any new functionality.  The fixes
+are mostly moved from the @code{unicode-math} package to this package since
+they are not directly related to Unicode mathematics typesetting.")
