+As of version $1.15$ (mid-2020), there is a new macro \verb|\textfrac| that may be used to construct simple fractions. For example, \verb|\textfrac[2]{7}{8}| renders as \textfrac[2]{7}{8}. (If the optional argument is not specified, you get just the fraction.) There are two options to {\tt fbb.sty} that may be used to modify the space before and after the solidus: {\tt foresolidus} and {\tt aftsolidus}, which should be specified in {\tt em} units. Their default values are {\tt .04em} and {\tt 0em} respectively.

Option {\tt altP} changes the form of the letter capital P from its default closed shape, as used in almost all modern digital renderings of Bembo, to the more historically accurate open shape, {\altp P}. See, for example, the reproduction of Pietro Bembo's \textit{De Aetna} at \url{https://ia601405.us.archive.org/34/items/ita-bnc-ald-00000673-001/ita-bnc-ald-00000673-001.pdf}. (A higher resolution rendering of a two-page sample is available from \url{https://upload.wikimedia.org/wikipedia/commons/8/89/De_Aetna_1495.jpg.}) Unicode \TeX\ users may load {\tt fbb} with the equivalent to {\tt altP} by the code block
