+5. Open theta has been replaced with closed theta in slot 03B8 and
+ rules ss05 and ss06 have been adjusted accordingly.
+6. **Oldstyle numerals**: These have been designed by Antonis
+ Tsolomitis for regular and bold series and can be selected by
+ `RawFeature=onum`. (Those for italic and bolditalic have been
+ designed by R. Alessi.)
+7. **Math Font**: This is a major and long-awaited enhancement
+ to Old Standard. The math font has been designed by Antonis
+ Tsolomitis from an old French book published by Gauthier-Villars
+ that used a font similar to Old Standard for Greek and a Bodoni font
+ for Latin. As both Bodoni and Old Standard were “romantic”
+ faces, it is hoped that they match up nicely, even if this remains
+ to be proven...<br/>
+ Two integrals are provided: a romantic one, which is selected by
+ default, and an upright version, which can be selected with
+ `StylisticSet=2`.
