## Notable Changes

### The default EC2 instance is m3.medium

AWS deprecated the m1.* instance type. Juju now uses the m3.medium as
the default instance type when provisioning machines in EC2.

 * m1.* instances will only be selected when specified using the
   "instance-type" constraint.

 * When no constraints are specified, the m3.medium type will be selected.

 * When constraints are specified, m1 instance types which satisfy
   the constraints will be ignored.


### Use the "storage" feature flag to try charms that support storage.

Storage was classified as experimental in 1.24, and has been found to be
problematic. Since storage is used implicitly by charms with default
stores, the feature was placed behind a feature flag. You can test
charms that support storage by bootstrapping a new environment with
"storage" enabled like so:

   JUJU_DEV_FEATURE_FLAG=storage juju bootstrap


## Resolved issues

 * Maas provider with maas 1.9 - /etc/network/interfaces "auto eth0"
   gets removed and bridge is not setup
   Lp 1494476

 * Switch default instance type from m1.small to t2.small/m3.medium
   for ec2 provider
   Lp 1373516

 * Destroy-environment reports warning cannot delete security group
   Lp 1335885

 * Storage should be behind a feature flag in 1.24
   Lp 1503740

 * Configstore should break fslock if time > few seconds
   Lp 1500613

 * Config-changed error does not cause error state
   Lp 1494542

 * Setapihostports shouldn't record just one address per api server
   Lp 1497094

 * Failed worker can result in large number of goroutines and open
   socket connections and eventually gets picked on by the oom killer
   Lp 1496750

 * Upgrade in progress reported, but panic happening behind scenes
   Lp 1493123

 * juju occasionally switches a units public-address if an additional
   interface is added post-deployment
   Lp 1435283
