## The complete release notes available on the Web

https://jujucharms.com/docs/devel/temp-release-notes
## Getting started with Juju 2.0
Juju 2.0 allows you to get started creating models without modifying any
definition files. Just provide your credentials and go! (*Note: to
fully understand the new bootstrap experience please see the "New
Bootstrap and Cloud Management Experience" section below)
* LXD provider (requires lxd 2.0.0~rc9 or later):
The LXD provider requires no credentials, so you can create a
controller by just specifying its name:
juju bootstrap <controller name> lxd
Note that the lxdbr0 bridge needs to be properly configured for the lxd
provider to work, for details see:
http://insights.ubuntu.com/2016/04/07/lxd-networking-lxdbr0-explained/
* Public Clouds:
Known public clouds can be listed with juju list-clouds:
juju list-clouds
CLOUD TYPE REGIONS
aws ec2 us-east-1, us-west-1, us-west-2, ...
aws-china ec2 cn-north-1
aws-gov ec2 us-gov-west-1
azure azure japanwest, centralindia, eastus2, ...
azure-china azure chinaeast, chinanorth

joyent joyent us-east-1, us-east-2, us-east-3, …
lxd lxd
maas maas
manual manual
rackspace rackspace lon, syd, hkg, dfw, ord, iad
Add your credentials using either:
juju add-credential <cloud>
or
juju add-credential <cloud> -f creds.yaml
or
juju autoload-credentials
When specifying just the cloud, juju add-credential will allow a new
credential to be added interactively. You will be prompted type the
required credential attributes. Example:
juju add-credential maas
credential name: hmaas
replace existing credential? [y/N]: y
auth-type: oauth1
maas-oauth:
credentials added for cloud maas
The new credentials.yaml file at: ~/.local/share/juju/credentials.yaml
The autoload tool will search for existing credentials for AWS,
OpenStack/Rackspace, and Google clouds. You will then be prompted for
which ones you'd like to save.
If you have an existing credential.yaml file, you can also import a
named credential, eg for MAAS
cat credentials.yaml
credentials:
maas:
my-credentials:
auth-type: oauth1
maas-oauth: <mass-oauth-key>
or, for AWS
cat credentials.yaml
credentials:
aws:
default-credential: my-credentials
my-credentials:
auth-type: access-key
access-key: <key>
secret-key: <secret>
Bootstrap using your default credentials:
juju bootstrap <controller name> <cloud>[/region]
Examples:
juju bootstrap aws-controller aws
juju bootstrap mass-controller maas/192.168.0.1
In the MAAS example above, you specify the host address of the MAAS
controller. So to use Juju on MAAS out of the box, you set up a
credentials file (either interactively, or based on the example above)
and then bootstrap. This avoids the need for any cloud configuration.
But it's also possible to set up a named MAAS cloud definition as
explained later.
More details on the new bootstrap experience, including defining private
clouds can be found in the New Bootstrap and Cloud Management Experience
section.
## What's New in Beta5
* Support for local charm repositories removed.
* All local charms must now be deployed using the path to the charm
instead of a local URL.
* Bundles support specifying local charms using the path to the charm.
* Notable Bug Fixes:
* GridFS namespace breaks charm and tools deduping across models
Lp 1569054
* Unable to download local: charm due to hash mismatch in
multi-model deployment
Lp 1541482
* Destroyed models still show up in list-models
Lp 1534627
## Notable Changes
This releases addresses stability and performance issues.
### Improved Local Charm Deployment
Local charms can be deployed directly from their source directory
without having to set up a pre-determined local repository file
structure. This feature makes it more convenient to hack on a charm and
just deploy it, and it also necessary to develop local charms
supporting multi series.
Assuming a local charm exists in directory /home/user/charms/mycharm:
juju deploy ~/charms/mycharm
will deploy the charm using the default series.
juju deploy ~/charms/mycharm --series trusty
will deploy the charm using trusty.
Note that it is no longer necessary to define a JUJU_REPOSITORY nor
locate the charms in a directory named after a series. Any directory
structure can be used, including simply pulling the charm source from a
VCS, hacking on the code, and deploying directly from the local repo.
Bundles are also supported. You can now do something like this:
series: xenial
services:
wordpress:
charm: ./wordpress
num_units: 1
series: trusty
mysql:
charm: ./mysql
num_units: 1
relations:
- ["wordpress:db", "mysql:server"]
Note the series attributes. These are required if the charm does not
yet define any default series in metadata or you want to use a series
different to the default. Either the bundle default series will be
used ("xenial" for the mysql service above) or the service specific
one will be ("trusty" for the wordpress service above).
