The changes in this release are performance changes:

• In the pool list and pool info views the requests to tsuru api to get unit data are asynchronous
• Use a specific index to get metric data from Elasticsearch

The main feature of this issue is the new app log page. Now the log page has buttons to enable and disable the autoscroll.

The other changes are the Django 1.9.1 support and a change in the metrics page that show metrics for apps without units.
