Documentation/Changes: add minimal requirements for documentation build
As discussed at linux-doc ML, the best is to keep all documents backward compatible with Sphinx version 1.2, as it is the latest version found on some distros like Debian. All books currently support it. Please notice that, while it mentions the eventual need of XeLaTex and texlive to build pdf files, this is not a minimal requirement, as one could just be interested on building html documents. Also, identifying the minimal requirements for texlive packages is not trivial, as each distribution seems to use different criteria on grouping LaTex functionalities. While here, update the current kernel version to 4.x. Signed-off-by: Mauro Carvalho Chehab <> Signed-off-by: Jonathan Corbet <>
