On the 1st June, Berkeley released version 7 of Seti@home. Version 7 Work Units (WUs) take longer to crunch (than version 6) so you will notice an increase in the time it takes to complete a WU. The stock v7 application can be obtained from Berkeley.
On 4th June, Lunatics Optimised Installer version 0.41 was released. You can get the Optimised Installer from: http://www.arkayn.us/forum/index.php (http://www.arkayn.us/forum/index.php).
