+ # History:
+ #
++# 2.4.2 Fix an issue where new versions of ImageMagick expect the order of
++#       options in command line execution of magick/convert. (See, for
++#       example, http://www.imagemagick.org/Usage/basics/#why.)
++#
++# 2.4.1 Add ability to dump LaTeX log file when using batch mode. Batch
++#       mode suppresses most output, often including error messages. To
++#       make sure critical error messages get displayed, show the full log
++#       on failures.
++#
++# 2.4.0 Remove "-r 600" from the default PDFTOPS_CONVERTER_FLAGS. The -r flag
++#       is available from the Poppler version of pdftops, but not the Xpdf
++#       version.
++#
++#       Fix an issue with the flags for the different programs not being
++#       properly separated.
++#
++#       Fix an issue on windows where the = character is not allowed for
++#       ps2pdf arguments.
++#
++#       Change default arguments for latex and pdflatex commands. Makes the
++#       output more quiet and prints out the file/line where errors occur.
++#       (Thanks to Nikos Koukis.)
++#
++#       After a LaTeX build, check the log file for warnings that are
++#       indicative of problems with the build.
++#
++#       Remove support for latex2html. Instead, use the htlatex program.
++#       This is now part of TeX Live and most other distributions. It also
++#       behaves much more like the other LaTeX programs. Also fixed some
++#       nasty issues with the htlatex arguments.
++#
+ # 2.3.2 Declare LaTeX input files as sources for targets so that they show
+ #       up in IDEs like QtCreator.
