If you want to be updated about service pack releases and other important Softimage news, turn on the Check for Announcements and Updates preferences (File > Preferences > General).
Then every time you start Softimage, announcements and updates will be displayed in the default Netview page. If this option is off, you can still click a link in the default Netview page to display them. If this option is on but Launch Netview on Startup is off, high-priority messages will still force Netview to open on startup.
Alternatively, you can subscribe to the RSS feed at http://softimage.wiki.softimage.com/motd/rss_en.xml using an RSS-aware browser.
