- Additional Nagios integration scripts
- Contributed by Etsy - stacked graph in the cluster view
- Ability to hide/show events on individual graphs or whole pages
- Numerous bug fixes and small enhancements

- gmetad supports sending metrics to graphite. Uncomment proper section of gmetad.conf to enable
- Default RRD resolution changed. It affects only newly created RRDs. To change to old behavior please modify the RRA field in gmetad.conf
