30 VDEF support. This is a variable containing one value
31 and a time component. This type of variable can hold
32 the result of a function over a complete time series
33 of data (DEF or CDEF) such as the maximum seen, and when.
35 2001/03/10 Jake Brutlag <jakeb@corp.webtv.net>
36 Support for COMPUTE data sources (CDEF data sources). Removes the RPN
37 parser and calculator from rrd_graph and puts then in a new file,
38 rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
39 clean-up of aberrant behavior stuff, including a bug fix.
40 Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
42 2001/03/07 Tobias Oetiker <oetiker@ee.ethz.ch>
43 Integrated complete rewrite
44 of rrdgraph documentation by Alex van den Bogaerdt

46 changes to the rrdgraph module
48 2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
49 Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
50 From now one, new rrd files use version tag 0002. They can
51 NOT be read by the old 1.0.x rrdtools.
53 Jake:
54 Aberrant Behavior Detection support. A brief overview added to
55 rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
56 other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
57 rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
58 leave the binary header unchanged for old files).
