- * Initial revision
+ * Revision 1.6 2004/05/26 22:11:12 oetiker
+ * reduce compiler warnings. Many small fixes. -- Mike Slifcak <slif@bellsouth.net>
+ *
+ * Revision 1.5 2002/02/01 20:34:49 oetiker
+ * fixed version number and date/time
+ *
+ * Revision 1.4 2001/08/22 22:29:07 jake
+ * Contents of this patch:
+ * (1) Adds/revises documentation for rrd tune in rrd_tool.c and pod files.
+ * (2) Moves some initialization code from rrd_create.c to rrd_hw.c.
+ * (3) Adds another pass to smoothing for SEASONAL and DEVSEASONAL RRAs.
+ * This pass computes the coefficients as deviations from an average; the
+ * average is added the baseline coefficient of HWPREDICT. Statistical texts
+ * suggest this to preserve algorithm stability. It will not invalidate
+ * RRD files created and smoothed with the old code.
+ * (4) Adds the aberrant-reset flag to rrd tune. This operation, which is
+ * specified for a single data source, causes the holt-winters algorithm to
+ * forget everthing it has learned and start over.
+ * (5) Fixes a few out-of-date code comments.
+ *
+ * Revision 1.3 2001/03/07 21:21:54 oetiker
+ * complete rewrite of rrdgraph documentation. This also includs info
+ * on upcomming/planned changes to the rrdgraph interface and functionality
+ * -- Alex van den Bogaerdt <alex@slot.hollandcasino.nl>
+ *
+ * Revision 1.2 2001/03/04 13:01:55 oetiker
+ * Aberrant Behavior Detection support. A brief overview added to rrdtool.pod.
+ * Major updates to rrd_update.c, rrd_create.c. Minor update to other core files.
+ * This is backwards compatible! But new files using the Aberrant stuff are not readable
+ * by old rrdtool versions. See http://cricket.sourceforge.net/aberrant/rrd_hw.htm
+ * -- Jake Brutlag <jakeb@corp.webtv.net>
