makefaq release 2.4 primarily provides a function that allows your FAQ data file to be exported into DocBook XML where it can then be processed into PDF or other formats using the standard DocBook processing tools and XSLT stylesheets. This allows the FAQ itself to remain in the very simple data format of makefaq, while allowing the higher level of formatting possible through DocBook tools.
The release also provides a new command-line option, -N, to suppress numbering of the questions. There were a number of minor changes to the format of the program itself, including the movement of comments into docstrings.
