Upgrade Instructions
====================

#. Download IScorE |release|

   Download iscore-|release|.tar.gz from ISEChest. Copy or extract the new files to your existing installation directory.

#. Update dependencies

   IScorE now requires ``libjpdeg-dev``, you can install it by running ``apt-get install libjpeg-dev``.

   To update the python dependencies, run ``pip install -r requirements.txt`` from the directory IScorE is installed in.

#. Update the database

   Due to the removal of outdated depdencies, IScorE |release| will require a fresh database. Simply dropping the IScorE
   database and re-creating it will suffice. Run ``python manage.py migrate`` to initialize the database.
