Since I updated this morning, I can't anymore compile even a minimal
XeLaTeX like this one:

-----
\documentclass{article}

\usepackage{fontspec}

\begin{document}

Hello world!

\end{document}
-----

The log reads as follows:

-----
(/usr/local/texlive/2012/texmf-dist/tex/latex/fontspec/fontspec.cfg
! Undefined control sequence.
<argument> \c_keys_code_root_tl 
                                fontspec/Ligatures/Historical
l.8 ...tureoption{Ligatures}{Historic}{Historical}

?
-----

Is anybody experiencing the same error after having fetched this
update?
