[CTAN Announcements]

The LaTeX Team submitted an update to the

                   l3build

package.

Version:  2021-11-29
License:  lppl1.3c

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

Announcement text:
----------------------------------------------------------------------
 
 ### Changed
 - Documentation improvements
 - Use `checkengines[1]` as the default for `stdengine`
 - Add sanity check for `TEXMFHOME` value
 - Double \ when writing the curl options, so that \
   does not need to be doubled in note and announcement texts.

 ### Fixed
 - Installation of files when using MiKTeX (see #125)
 - Incorrect line in `manifest` target (see #195)
 - Placement of PDF files in subdirectory locations (issue #209)
 - Detection of engine-specific tlg files for non-standard LuaTeX based engines (issues #214)
