Changes RRDTOOL3
===============================================================================

3.4.1:
------

3.5.0:
------
2009-07-28 babel
    - start update to rrdtool 1.3.8. This is a really BIG change.
      rrdtool now uses a bunch off external libraries and is able
      to generate more output formats then before. With this switch
      we start using collectd to collect the RRA data. This renders
      the old rrd databases useless (or someone is fine enough to
      write a convert script).
2009-08-11 babel / bastard
    - add patch for typ b installation. collectd doesn't load plugin
      that are symlinks.
2009-12-03 babel
    - update rrdtool to 1.4.2 and bump version for collectd and other
      libs too.
2010-08-29 tiger
    - Restarting script development from scratch.
    - RRDTOOL3_DB_PATH defaults to /boot/rrdtool to ensure a valid path
    - /var/run/rrdtool3.conf is created during boot making the patching of
      *.inc files obsolete.
    - Merged collectd and rrdtool3 graph configurations in /etc/rrdtool3/*.inc
    - Added httpd GUI language support.
    - Configuration is tab-oriented, now. You can configure any tab arrangement
      with one level of sub-tabs.
    - Several graphs per tab.
    - The configuration allows multiple dataset from the same source (plugin)
      to be rendered in the same graph. Simply state the appropriate plugin
      parameters separated by plus (+) characters in the _GRAPH property of the
      tab.
    - Added loads of variables to make the GUI as versatile as possible.
    - Most plugins can be adjusted to your needs through the new variables added.
