A new release of Juju is here, 2.3-rc1. This is primarily a bug fix release
which addresses issues carried over from beta3.

## New and Improved

* Changed flags for deploying bundles to existing machines

When deploying bundles, machines specified in the bundle are added to the
model as new machines. In order to use the existing machines in the model
rather than create new machines, the option --map-machines=existing can be
used. To specify particular machines for the mapping, multiple comma
separated values of the form "bundle-id=existing-id" can be passed where
the bundle-id and the existing-id refer to top level machine IDs. For
example, if there were a bundle that specified machines 1, 2, and 3, and
the model had machines 1, 2, 3 and 4, the following deployment of the
bundle would use machines 1 and 2 in the model for machines 1 and 2 in the
bundle and use machine 4 in the model for the bundle machine 3.

 juju deploy some-bundle --map-machines existing,3=4

* Bundle deploy flag --bundle-config replaced with --overlay.

The bundle config files used to allow overwriting configuration values of
applications that had already been defined in the base bundle, but did
nothing else.

The overlay files are now full bundles in their own right. The overlay
bundle can specify new applications, change values like the previous
bundle-config files, and also specify the removal of an application in the
base bundle. An application can be removed from the bundle definition by
defining the application name in the application section, but no values
specified. Removing an application also removes all the relations for that
application. If a machines section is specified in an overlay bundle it
replaces the machines section of the base bundle. No merging of machine
information is attempted. Multiple overlay bundles can be specified and
they are processed in the order they appear on the command line.
