Version number: 2018-03-08
License type: lppl1.3c

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

Announcement text:
# Release 2018-03-08

## l3build as a stand alone script

>From this release, l3build may be used directly rather than requiring
'calling' from a build.lua wrapper. This will allow l3build to be
installed as a script in common TeX distributions: the team anticipate
that this will lead to the much simplified usage

    l3build <command> [<options>] [<names>]

At present, l3build will continue to work with existing build.lua
files, but the team recommend that these are updated to the 'new'
style: all that is required is to remove the lines


and then to use the new invocation.

## Tagging

Supporting this change, various options have been added and removed:
see the documentation for full details. In particular, the "setversion"
command has been replaced by "tag", which is modelled on the Git
command of the same name. This will require updated build.lua files for
users of "setversion", but allows a more flexible approach. It also
avoids the confusion on what 'version' means, as the updated script uses

    l3build --version

in the normal way to print the version of the script itself.

Tagging is carried out for example by

    l3build tag 2018-03-05

## Support for scripts

To allow this change, new variables "scriptfiles" and "scriptmanfiles"
have been added. These allow the inclusion of scripts in packages, and
also the provision of Unix man files.

## Preparations for TeX Live 2018

The upcoming TeX Live release will feature updated engines. Some
normalisation code has been adjusted to allow for LuaTeX and (u)pTeX
changes. These will of course already be of relevance to MiKTeX users.
