To save typing, here's a cut & paste from the wiki post. Enjoy the new
features and please let me know if you run into any issues.

*Graphite 0.9.8 is now out and available for download*. It available through
PyPI (http://pypi.python.org/pypi) and the Launchpad project page (
https://launchpad.net/graphite).

This release is a major step forward for Graphite, with a long list of
substantive enhancements only 3 months after the last release. One of the
highlights is the move of our documentation to readthedocs.org, the docs are
now built using Sphinx and they live in trunk under the 'docs' folder. Just
commit any changes and readthedocs.org will automatically update by pulling
changes from launchpad nightly.

A special thanks goes out to AppNexus (http://appnexus.com/), who sponsored
the development of two awesome new features. First is the new
carbon-aggregator daemon. This new daemon lets you configure the calculation
of aggregate metrics at storage time instead of using a heavy-weight
sumSeries or averageSeries at rendering time. This daemon can also rewrite
metric names. You manage it like the other two carbon daemons, via
carbon.conf. Documentation on configuring carbon-aggregator will be coming
soon.

AppNexus also sponsored the development of the new Dashboard UI. This new
interface allows you to put together dashboards containing many graphs
quickly and easily. You can save a dashboard and view it later. Note that
this is a basic implementation for now,

Beyond that, there are many other new features so please read through the
changelog carefully.
