43 VDEF support. This is a variable containing one value
44 and a time component. This type of variable can hold
45 the result of a function over a complete time series
46 of data (DEF or CDEF) such as the maximum seen, and when.
48 2001/03/10 Jake Brutlag <jakeb@corp.webtv.net>
49 Support for COMPUTE data sources (CDEF data sources). Removes the RPN
50 parser and calculator from rrd_graph and puts then in a new file,
51 rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
52 clean-up of aberrant behavior stuff, including a bug fix.
53 Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
55 2001/03/07 Tobias Oetiker <oetiker@ee.ethz.ch>
56 Integrated complete rewrite
57 of rrdgraph documentation by Alex van den Bogaerdt
58 <alex@ergens.op.Het.Net>. This also contains info on his planned
59 changes to the rrdgraph module
61 2001/03/02 Tobias Oetiker <oetiker@ee.ethz.ch>
62 Added Aberrant Patch from Jake Brutlag <jakeb@microsoft.com>
63 From now one, new rrd files use version tag 0002. They can
64 NOT be read by the old 1.0.x RRDtools.
66 Jake:
67 Aberrant Behavior Detection support. A brief overview added to
68 rrdtool.pod. Major updates to rrd_update.c, rrd_create.c. Minor update to
69 other core files. Updated documentation: rrdcreate.pod, rrdgraph.pod,
70 rrdtune.pod. This is backwards compatible (i.e. new tool can read and will
71 leave the binary header unchanged for old files).
