    Hi all,

    Another new stable sysstat release has been made available on my web site. In
    this new version (5.0.2), iostat will _again_ be able to look for extended
    statistics in /proc/partitions if available.
    This feature was removed in sysstat 4.1.3, but too many production servers are
    still using 2.2.x or 2.4.x kernels with extended stats in /proc/partitions, and
    iostat must be able to display them...

    Also keep in mind that this new 5.0.2 release can be used with *all* Linux
    kernels, including recent cutting-edge 2.6.x ones.

    sysstat 5.0.2 is available for download from my web page at:
    http://perso.wanadoo.fr/sebastien.godard/

    It will also be available on ibiblio's Linux archive site any day now:
    ftp://ibiblio.org/pub/Linux/system/status/
    116kB sysstat-5.0.2.tar.gz
    94kB sysstat-5.0.2.tar.bz2
    119kB sysstat-5.0.2-1.src.rpm
    82kB sysstat-5.0.2-1.i386.rpm

    The sysstat utilities are a collection of performance monitoring tools for
    Linux. These include sar, mpstat, iostat and sa tools.
    Feedback always welcomed . Send your remarks, comments, etc. at my new e-mail
    address: <sysstat[at]wanadoo.fr>.

    Enjoy!

    Changes vs 5.0.1 are:
    * iostat will _again_ look for statistics in /proc/partitions if available. So
    now, iostat gets its statistics from the following sources in that order:
    /proc/diskstats, sysfs, /proc/partitions and then /proc/stat.
    * statistics are now read by iostat and mpstat as unsigned long instead of int
    to avoid integer overflow.
    * iostat should now handle properly the case when the 'weighted number of
    milliseconds spent doing I/Os' (read in sysfs or /proc/{partitions,diskstats})
    decreases with time.
    * iostat manual page updated.
    * Minor temporary file vulnerability fixed in isag command.
    * README, FAQ and CREDITS files updated.
    * Author's email changed.
