I am pleased to announce the availability of a patch release in the Juju 0.5 series, v0.5.2

The 0.5 series is the current stable series of juju, and so is in maintenance mode. This release
encompasses only bug fixes and backported provider support (In this case, OpenStack). Please note
that juju is still experimental software.

Notable changes include:

 * Backported OpenStack provider (Tested with private OpenStack Essex and HPCloud)
 * 0.5 PPA allows using juju-origin PPA w/o getting latest trunks
 * SSL certs verified for all communication with charm store
