NAME

       latex-dev,  pdflatex-dev, xelatex-dev, lualatex-dev, dvilualatex-dev, platex-dev, uplatex-
       dev - release candidate LaTeX testing

SYNOPSIS

       latex-dev [first-line]

DESCRIPTION

       These -dev executables are intended for testing  upcoming  LaTeX2e  kernel  changes.  They
       correspond  to  new  formats  which  have  been tested by the LaTeX team for stability and
       usability.  Thus,  they  are  not  arbitrary  development  snapshots;  more  like  release
       candidates.

       Wider  testing  by  knowledgeable  users is desired, indeed, is the main purpose for these
       executables to exist. Simply replacing the regular engine (e.g., pdflatex) with  the  -dev
       engine name (pdflatex-dev) is all that should be needed.

       The lualatex-dev format is based on luahbtex, the luatex variant with harfbuzz enabled for
       glyph shaping.

       Please report bugs in  these  -dev  versions,  like  all  LaTeX  releases,  following  the
       procedure at https://www.latex-project.org/bugs.
