New Features
* automatic x-axis labels that work from 1s to 30y on a single chart
* librados integration
* new datasource types: DCOUNTER and DDERIVE (they work the same as
  the original DS, except that they can deal with floatingpoint
* compile without graphics libraries: ./configure --disable-rrd_graph
* updated windows port (see WIN32-BUILD-TIPS.txt)
* single step RRAs for MIN,MAX,LAST are generated virtually from
* ignore updates in the past with rrdtool update --skip-past-updates
* ignore a LINE when scaling a chart using the skipscale option
* detect 32bit timeoverflows
* massive performance boost for charts with more than 100 DEF line
* by switching form a linear search to a HASH when searching for data
* improved cross compilation support
* .Net bindings
* allow rrdtool graph to silently skip non-existing source files
  using the --use-nan-for-all-missing-data option
* restore from a pipe (rrdtool restore - y.rrd)
* in rrdtool create, row count and step can be defined in absolute time
* all new "create on steroids" can pull both data and configuration
* from existing rrd files
* use rrdtool graph to chart arbitrary data via a callback function
  for data fetching support is integrated in the perl bindings.
* re-written parser for rrdtool graph commands. It now follows a
  simple key  value pattern, compatible with the previous syntax.
* MEDIAN op for CDEF expressions
* DEPTH,INDEX,COPY,ROL ops for CDEF (as seen in PostScript)
* gradient AREA backgrounds
* no more locale magic while reading numeric data.

all the bugs fixed in 1.4.x during 1.5 development
