- * 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
+ * Revision 1.7 2004/05/25 20:53:21 oetiker
+ * prevent small leak when resources are exhausted -- Mike Slifcak
+ *
+ * Revision 1.6 2004/05/25 20:51:49 oetiker
+ * Update displayed copyright messages to be consistent. -- Mike Slifcak
+ *
+ * Revision 1.5 2003/02/13 07:05:27 oetiker
+ * Find attached the patch I promised to send to you. Please note that there
+ * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
+ * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
+ * library is identical to librrd, but it contains support code for per-thread
+ * global variables currently used for error information only. This is similar
+ * to how errno per-thread variables are implemented. librrd_th must be linked
+ * alongside of libpthred
+ *
+ * There is also a new file "THREADS", holding some documentation.
+ *
+ * -- Peter Stamfest <peter@stamfest.at>
+ *
+ * Revision 1.4 2002/02/01 20:34:49 oetiker
+ * fixed version number and date/time
+ *
+ * Revision 1.3 2001/03/10 23:54:39 oetiker
+ * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
+ * parser and calculator from rrd_graph and puts then in a new file,
+ * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
+ * clean-up of aberrant behavior stuff, including a bug fix.
+ * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
* -- Jake Brutlag <jakeb@corp.webtv.net>
