As a result of updating the l3kernel, l3packages, and l3experimental, a XeTeX document I'm working on no longer compiles. I've narrowed down the problem to fontspec failing to find a control sequence that was seemingly earlier available. The minimum working example would be:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Tinos}
\begin{document}
This is a minimal working example.
\end{document}

It fails to compile with the log:

This is XeTeX, Version 3.14159265-2.6-0.99992 (TeX Live 2015) (preloaded format=xelatex)
\write18 enabled.

    We've recently removed some deprecated functions and Will obviously left one in fontspec. I'll prod him to fix it: for the moment, \usepackage{expl3}\ExplSyntaxOn\cs_set_eq:NN \str_case:nnn \str_case:nnFcs_set_eq:NN \str_case_x:nnn \str_case_x:nnF\ExplSyntaxOff. – Joseph Wright Jul 17 '15 at 09:59
  • Kurt, Tinos is a freely available font downloadable from Google fonts. – ashinpan Jul 17 '15 at 10:21
  • Joseph, thanks. I think I have some time to spare, so I will wait until Will fixes fontspec. Given his track record, I think he will do it very soon! – ashinpan Jul 17 '15 at 10:22
  • There is a typo in Joseph's comment; the correct code has a backslash instead of the capital F. \usepackage{expl3} \ExplSyntaxOn \cs_set_eq:NN \str_case:nnn \str_case:nn \cs_set_eq:NN \str_case_x:nnn \str_case_x:nnF \ExplSyntaxOff – Alex Hirzel Aug 13 '15 at 22:07
  • I'm voting to close this question as off-topic because it is caused by a passing issue in a package. – Joseph Wright Oct 29 '15 at 19:42
