La cosa più interessante sembra essere il SSL Switchover Support.
Joomla! 1.0.12 has reintroduced SSL switchover support. If your website is setup to serve the same files via HTTP or HTTPS you will now be able to create SSL secured logins, easily switch between secure and insecure navigation and do all of your administrative tasks via an SSL protected connection. A FAQ on how to setup these features will be available soon in the Security FAQs section of the Joomla! forums.
A quando la release italiana?
