Yes. From microtype.pdf: "Note that font expansion and character protrusion will only work with pdfTEX, at least version 0.14f. Automatic font expansion requires version 1.20 or newer. Disabling ligatures requires pdfTEX 1.30, letterspacing and the adjustment of interword spacing and of kerning requires version 1.40." So with pdfTeX 1.21, you cannot use the spacing and kerning options. Jürgen
