The LaTeX Team  submitted an update to the

      l3build + l3kernel + l3packages + l3experimental


Version:  2017-04-01

Summary description:  A testing and building system for (La)TeX

Announcement text:

 Release 2017-04-01

 Boolean functions

 This release marks the functions

 - \bool_lazy_all:n(TF)
 - \bool_lazy_and:nn(TF)
 - \bool_lazy_any:n(TF)
 - \bool_lazy_or:nn(TF)

 as stable. This will be followed at a later date by a change in
 \bool_if:n(TF), which will move to being greedy: this change is
 necessary as there are circumstances under which \bool_if:n(TF)
 currently fails with a low-level error due to lazy evaluation.

 Package authors are encouraged to consider employing these new
 functions where appropriate.

 Version identifiers

 From this release the SVN $Id lines are removed from LaTeX3 sources.
 The function \GetIdInfo is deprecated from this release, and the
 team recommend that package authors include version information
 directly in \ProvidesExplPackage (or similar) lines.


 Internal changes are focussed on compatibility with LuaTeX v1.04+.
