RRDtool 1.5.0-rc1 - 2015-01-08
==============================

New Features
------------
* new datasource types: DCOUNTER and DDERIVE (they work the same as
* the
  original DS, except that they can deal with floatingpoint
* numbers).
* 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
  an AVERAGE RRA
* 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)
