42 the result of a function over a complete time series
43 of data (DEF or CDEF) such as the maximum seen, and when.
45 2001/03/10 Jake Brutlag <jakeb@corp.webtv.net>
46 Support for COMPUTE data sources (CDEF data sources). Removes the RPN
47 parser and calculator from rrd_graph and puts then in a new file,
48 rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
49 clean-up of aberrant behavior stuff, including a bug fix.

56 changes to the rrdgraph module
58 2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
59 Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
60 From now one, new rrd files use version tag 0002. They can
61 NOT be read by the old 1.0.x rrdtools.
63 Jake:
64 Aberrant Behavior Detection support. A brief overview added to
65 rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
66 other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
67 rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
68 leave the binary header unchanged for old files).
