Juju 2.4-rc3 has been released

[Ian Booth]

A new development release of Juju is here, 2.4-rc3.

This release candidate addresses an issue upgrading from earlier Juju versions
as described below.

## Fixes

An upgrade step has been added to initialise the Raft configuration. This would
normally be done at bootstrap time but needs to be done during upgrade for
controllers that were bootstrapped with an earlier version.

## How can I get it?

The best way to get your hands on this release of Juju is to install it as a
snap package (see https://snapcraft.io/ for more info on snaps).

         sudo snap install juju --classic --candidate

Other packages are available for a variety of platforms. Please see the online
documentation at https://jujucharms.com/docs/stable/reference-install. Those
subscribed to a snap channel should be automatically upgraded. If you’re using
the ppa/homebrew, you should see an upgrade available.
