0.9.14
===========================
*11/7/2015*

Graphite 0.9.14 is now available for usage. Source bundles are available from GitHub:

* https://github.com/graphite-project/graphite-web/archive/0.9.14.tar.gz
* https://github.com/graphite-project/carbon/archive/0.9.14.tar.gz
* https://github.com/graphite-project/whisper/archive/0.9.14.tar.gz

Graphite can also be installed from `PyPI <http://pypi.python.org/>`_ via
`pip <http://www.pip-installer.org/en/latest/index.html>`_. PyPI bundles are here:

* http://pypi.python.org/pypi/graphite-web/
* http://pypi.python.org/pypi/carbon/
* http://pypi.python.org/pypi/whisper/

Upgrading
---------
Graphite 0.9.14 now requires a Django version of at least 1.4. Ensure this dependency is satisfied before updating *graphite-web*.

As always, comparing the example config files with existing ones is recommended to ensure awareness of any new features.

Graphite-web's application database will need to be upgraded for a new Django fixture. It's a good idea to backup the database before proceeding with the migration. The following will upgrade a SQLite database:

.. code-block:: none

  sudo cp /opt/graphite/storage/graphite.db \
        /opt/graphite/storage/graphite.db.backup-`date +%Y%m%d_%H%M%S`
  sudo PYTHONPATH=/opt/graphite/webapp django-admin.py syncdb \
        --noinput --no-initial-data --settings=graphite.settings

Security Notes
