46 the result of a function over a complete time series
47 of data (DEF or CDEF) such as the maximum seen, and when.

50 Support for COMPUTE data sources (CDEF data sources). Removes the RPN
51 parser and calculator from rrd_graph and puts then in a new file,
52 rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
53 clean-up of aberrant behavior stuff, including a bug fix.

60 changes to the rrdgraph module
62 2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
63 Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
64 From now one, new rrd files use version tag 0002. They can
65 NOT be read by the old 1.0.x RRDtools.
68 Aberrant Behavior Detection support. A brief overview added to
69 rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
70 other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
71 rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
72 leave the binary header unchanged for old files).
