CCP just pushed out the first half of two major updates coming this summer, kicking off what they're calling EVE Online's "Summer of Sovereignty."
Here's how CCP describes the update:
Carnyx begins the Sov rush with new modules and gameplay for the theatre of war. Massive player empires have fortified themselves in strategic solar systems in anticipation of changes that encourage active use of space through an occupancy-based defense multiplier. The new Sovereignty brings opportunities for those wishing to get into nullsec and offers plenty of mayhem for small gangs to skirmish with their enemies. Carnyx's changes will ease players into the new capture mechanics by first affecting station services. Come Aegis, all Sovereignty structures will be under the sway of those willing and able to use an Entosis Link on capture objectives and wrest control away from foes.
