This release adds graph zooming. Zooming happens in-place (no separate window). It adds mouseovers that display time under the cursor. You can optionally specify heartbeat, step, and resolution per host/service.
There is a fix to Javascript to display hosts and services when specified via CGI, even if they do not appear in the host and service menus. It fixes a bug in handling of backslashes in service and database names. It adds support for rrdtool STACK. The stack can be specified using the 'stack' directive and/or using the 'lineformat' directive. See nagiosgraph.conf for details and examples.
JavaScript and page header layout were updated. More page style was moved into CSS. The lineformat and plotas options were added to allow more customization of graphs. Many other bugs were fixed.
