# juju-core 1.24.7

A new proposed stable release of Juju, juju-core 1.24.7, is now available.

This release may replace version 1.24.6 on Thursday October 22.


## Getting Juju

juju-core 1.24.7 is available for Wily and backported to earlier

series in the following PPA:

   https://launchpad.net/~juju/+archive/proposed

Windows, Centos7 and OS X users will find installers at:

   https://launchpad.net/juju-core/+milestone/1.24.7

Proposed releases use the "proposed" simple-streams. You must configure

the `agent-stream` option in your environments.yaml to use the matching

juju agents.


## 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
