Changes

Note that the legacy command <texcode>\sc</texcode> should be considered deprecatedused <em>only</em> for those few typefaces where the small caps belong to a font file distinct from the main font. Latin Modern is an example.  For most (if not all) contemporary opentype fonts, the small caps (and the associated feature <code>smcp</code>) are included in the main font file; it so <code>\sc</code> should no longer be used- and will not work across all weights - in most instances.
