36 2001/07/19 Alex van den Bogaerdt <alex@ergens.op.Het.Net>
37 VDEF support. This is a variable containing one value
38 and a time component. This type of variable can hold
39 the result of a function over a complete time series
40 of data (DEF or CDEF) such as the maximum seen, and when.
42 2001/03/10 Jake Brutlag <jakeb@corp.webtv.net>
43 Support for COMPUTE data sources (CDEF data sources). Removes the RPN
44 parser and calculator from rrd_graph and puts then in a new file,
45 rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
46 clean-up of aberrant behavior stuff, including a bug fix.
47 Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
49 2001/03/07 Tobias Oetiker <oetiker@ee.ethz.ch>
50 Integrated complete rewrite
51 of rrdgraph documentation by Alex van den Bogaerdt
52 <alex@ergens.op.Het.Net>. This also contains info on his planned
53 changes to the rrdgraph module
55 2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
56 Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
57 From now one, new rrd files use version tag 0002. They can
58 NOT be read by the old 1.0.x rrdtools.
60 Jake:
61 Aberrant Behavior Detection support. A brief overview added to
62 rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
63 other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
64 rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
65 leave the binary header unchanged for old files).
