The ejabberd version number

The ejabberd version number is read from the file ejabberd.app, the attribute vsn. And that number is extracted from the git tag when compiling ejabberd:

configure.ac:
AC_INIT(ejabberd, m4_esyscmd([echo `git describe --tags 2>/dev/null || echo 0.0`
 | sed 's/-g.*//;s/-/./' | tr -d '\012']), [ejabberd@process-one.net], [ejabberd])

So, in your case if git isn't available, it uses the default value. If you are really interested, you can simply force that number in the file 'configure', lines:

PACKAGE_VERSION='16.09.8'
PACKAGE_STRING='ejabberd 16.09.8'
