We have just updated the released alchemist repository. This is the same content that was pushed to alchemist_beta last Monday

An updated installer ISO and ZIPs are also included. Major changes here include fully unattended installation (no more mucking around with steam/desktop logins and manually running scripts), multiple language support and pre-installing all the firmware packages.
