662 changed IEEE tests ... now they tell you what fails and they are less picky
664 + 1999/08/12 -- Alex + Tobi
665 added INF and NEGINF operator to CDEF rpn functions. This pushes an
666 positive or negative infinite number onto the stack respectively ... when
667 graphing, they get replaced by a value equivalent to the upper or lower
668 boundery of the graphing area ...
671 Integrated Blairs autoconf ... added dist and install support
673 + 1999/08/09 -- Blair
674 Added automake/libtool support ... with --enable-shared you can
675 now get a shared library version of rrdtool ...
677 = 1.0.4 1999/08/06 -- tobi oetiker <tobi@caida.org>
680 made rrdcgi parser more robust to invalid inputfiles.
682 - 1999/08/04 -- Tobi + Philippe
683 in rrd_cgi I was freeing cgi arguments. Fixed ...
685 + 1999/08/03 -- Tobi Oetiker <tobi@caida.org>
686 added % operator to CDEF rpn functions ...
687 this should allow for some funky operations in connection with TIME
689 + 1999/08/03 -- Tobi Oetiker <tobi@caida.org>
690 added --enable-site-perl option to configure
691 for people who want the RRD{s,p} perl modules installed
692 in their site-perl directories
694 + 1999/08/03 -- Tobi Oetiker <tobi@caida.org>
695 do not try to compile perl modules if no perl is found
697 - 1999/08/02 -- Hermann Hueni <hueni@glue.ch>
698 drop "rb" open mode for non win32 architectures
700 - 1999/07/30 -- Tobias Weingartner <weingart@cs.ualberta.ca>
701 spell fixes for documentation
703 = 1.0.3 1999/07/30 -- tobi oetiker <tobi@caida.org>
706 Fixed default start time in rrd_create.
707 Start time of new rrds was set to 1970.01.01 causing VERY long update times
708 for the initial update ...
710 = 1.0.2 1999/07/28 -- tobi oetiker <tobi@caida.org>
713 Added configure checks for reallocs ability to deal with NULL pointers
714 this helps compiling on SunOS
717 Added check for memmove availablility. Replace with bcopy if necessary.
720 Added better IEEE tests ...
723 Added Dynamic stack allocation to RPN in CDEF
725 + 1999/07/27 -- Tobi & Tobias Weingartner <weingart@cs.ualberta.ca>

728 + 1999/07/27 -- Sasha Mikheev <sasha@aldan.netvision.net.il>
729 alternate grid and scaling functions for rrdgraph. Use --alt-y-grid and
730 --alt-autoscale to activate.
733 fixed about 1000 memmory leaks in rrdcg. Wonder it was working before ...
735 - 1999/07/26 -- Tamas Kovacshazy <khazy@mit.bme.hu>
736 improved vc++ project files for rrdtool
739 added ranlib to cgi png z and gd library ...
741 = 1.0.1 1999/07/23 -- tobi oetiker <tobi@caida.org>
744 plugged memory leek in parsetime.c
746 fixed serious error in data_reduce function. This was causing the graph to
747 intermittently disappear. It was also displaying inaccurate values for
748 spiky data, if this data had to be reduced due to the width of the image
749 as compared to the resolution of the RRA data. (does this fix the errors
750 seen by cricket users ????)
752 + 1999/07/22 -- Seth Lepzelter <slepzelt@cs.oberlin.edu>
753 DEC needs -mieee to do proper IEEE math ... added configure test

763 available on all systems.
765 = 1.0.0 1999/07/15 -- tobi oetiker <tobi@caida.org>
