Hello all,

I have recently submitted the following update to CTAN.

 - Adjustments to xparse to allow document commands to continue
   to function inside csnames: note that the team expect to give
   a clear statement on the scope of use of document commands in
   the near future
 - \NewExpandableDocumentCommand and related commands have been
   added to xparse
 - \IfValue(TF) is now marked as stable
 - There have been some questions about the (removed) k-type
   argument: see http://tex.stackexchange.com/q/357187 for
   some transitional code (note that the replacement e-type
   *is experimental*)

 - New package to provide a document level interface to the LaTeX3 FPU:

 - New \tl_range:nnn function
 - Reduction in use of \c_<number> constants in favour of explicit

 - Normalisation of lines from luaotfload added
 - Better performance of cmdcheck target when working with
   file bundles

As usual, this may take a day or so to propagate.
