A substantial number of changes will be made to EVE Online tomorrow with the Dominion 1.1 patch. The supercarrier changes and introduction of fighter bombs coming in 1.1 were originally slated for the Dominion expansion's launch last month but had to be postponed. Beyond the changes impacting EVE's capital ship pilots, nullsec warfare will be affected by how CCP is altering the stats of Sovereignty structures. (Territorial Control Units will receive increased hitpoints with reduced onlining time, likewise Sovereignty Blockade Units are getting a defensive buff.)
New features are being introduced as well, like voice fonts for the Vivox-powered EVE Voice.
