fontspec cannot be loaded after babel any longer

[ralessi]

With the latest versions of both babel and fontspec, this mwe compiled with lualatex:

\documentclass{article}
\usepackage[english]{babel}

\usepackage{fontspec}

\begin{document}
Hello world.
\end{document}

gives me this error:

ERROR: LaTeX error: "kernel/command-already-defined"

--- TeX said ---

l.121 \tl_new:N \latinencoding

pointing to l. 121 of fontspec-luatex.sty

If fontspec is loaded before babel, the mwe compiles. Are we now supposed to mind the load order of the two packages?

Apologies, this is an oversight. Thanks for letting me know. Until I fix the bug and make a new release, you can work around the issue as follows: \usepackage[english]{babel} \let\latinencoding\relax \usepackage{fontspec} (or revert to the previous version)

Many thanks! I already did \let\latinencoding\relax: everything is now back to normal.
