Comment 1 for bug 528220

The rabbitmq-server bug fixes relevant to Ubuntu in the 1.7.2 release are:

- make 'rabbitmq-multi start_all <n>' work again for n>1

- issuing a basic.qos when there are outstanding acks can no longer result in a higher limit than requested

- enforce codec size limits, thus preventing the server from sending invalid AMQP frames

- remove the explicit setting of TCP buffer sizes in the server, thus allowing auto-(re)sizing to occur. This generally results in substantially improved throughput over high-latency links, and makes manual fine-tuning easier.

- introduce declarative boot sequencing, which allows plugins to be started at arbitrary chosen points during the sequence

- add rabbitmqctl list_channels and list_consumers commands, and add exclusivity information to list_queues. Also introduce a close_connection command to allow an administrator to selectively terminate client connections. See the updated admin guide at http://www.rabbitmq.com/admin-guide.html for details on these new features.

The database schema has not changed since the 1.6.0 release, so user accounts, durable exchanges and queues, and persistent messages will all be retained during the upgrade.
