== Major expansions ==

=== Second Genesis ===
Release date: May, 2003

=== Castor ===
Release date: December 18, 2003
Castor was the first named content release, with one of the key features being the addition of the first special Tech 2 components and ships through research agents, and improvements and tweaks to the mission system launched in earlier patches. During the pre- and post- Castor patch cycle Eve players saw the introduction of conquerable stations in 0.0 security (lawless space) systems, the introduction of the agent mission running system, and the introduction of various NPC agents to help players gain in-game currency and faction standing through missions, the EVE equivalent of quests in other MMO's.

=== Exodus ===
Release date: November 17, 2004

Main features of Exodus were the introduction of alliances between corporations and the ability for said alliances to claim ownership of a lawless (0.0) solar systems via "player owned starbases.", which were also a major new feature in the patch. Deadspace complexes - areas in space guarded by hostile NPC's, with chance of getting special loot - were also introduced in Exodus.

=== Exodus: Cold War ===
Release date: June 29, 2005
Cold War Edition contained an extensive new tutorial sequence and a storyline background introduction. Introduced in Cold War were "COSMOS" constellations where in-space agents began giving out story-driven missions and unique rewards. The freighter and dreadnought capital ships, full-fledged player-owned "outposts," and improved NPC pirate factions improved alliance -based gameplay. This expansion also added Unicode chat support, allowing communication in Asian, Cyrillic, and Greek languages.

=== Red Moon Rising ===
Release date: December 16, 2005
Red Moon Rising was split off from the Revelations -expansions in order to maintain a more regular expansion schedule. In addition to various performance optimizations and tweaks, key features associated with the RMR expansion were the introduction of 39 new ships - most notably the introduction of the carrier, mothership and Titan -class capital ships, the expansion of the COSMOS feature from Cold War, and the addition of four new Asian-inspired bloodlines for players to choose from: The Achura for the Caldari State, Jin-Mei for the Gallente Federation, Khanid for the Amarr Empire and the Vherokior for the Minmatar Republic.

=== Revelations I ===
Release date: November 29, 2006
Revelations was scheduled to be released in three parts under the codename "Kali". Major features of this expansion included an exploration system for scanning down various sites - combat, mining areas normally not visible, a proper contract system for trading or auctioning items, the replacement of the previous "Tech 2 research lottery" with the invention mechanic, ship customization with rigs, temporary combat boosters, and eight new regions of space to conquer.Eve Voice was integrated as part of Revelations content patch 1.4, initially planned for release with Revelations II. Eve Voice is a Voice over IP tool integrated into the Eve Online client, with software licensed by CCP from Vivox.

=== Revelations II ===
Release date: June 19, 2007
Revelations II was the second of three expansions, designed to show the increased tensions between the empires within the game universe. Several new features were introduced; including a mechanism for overloading modules and area of effect bombs. A number of existing features have been extended including Level 5 agents, changes to sovereignty, starbases, outposts, and balancing changes to the Amarr race. Revelations II also changed the way new players start the game, in addition to new optional tutorials the existing tutorial has been shortened and refined, and players now start in a private dungeon to allow new players to get used to the controls in a protective environment.

=== Trinity ===
Release date: December 5, 2007Trinity was the third of the "Kali" expansions. Its biggest changes were the update of the game's graphics engine and addition of 5 new ship classes: Heavy Interdictors, Electronic Attack Ships, Black Ops, Marauders and Jump Freighters, capable of using the jump drive to travel through low security space without using stargates.  "Factional Warfare," a major addition to game mechanics, had been planned for this patch but was later announced that it would be included in a future patch, along with Ambulation (walking in stations and Full Human Representation, announced on the Eve Online Fanfest 2007). From the release of Trinity until the Apocrypha expansion CCP offered two editions of the game client; Classic for users who could not run the new graphics content on their computer, and Premium for those with a Shader Model 3-capable graphics card.The initial launch version of the Trinity patch would under certain circumstances delete Windows XP's boot.ini file, thus rendering the operating system unbootable. Six hours after the release of this faulty patch CCP fixed the issue. While the number of affected players is unknown, 215 had specifically asked CCP for assistance.

=== Empyrean Age ===
Release date: June 10, 2008
Empyrean Age, previously named Kali 4, was the ninth expansion of Eve Online and the last one in the Kali tetralogy. CCP included the Factional Warfare in this release. In this expansion the in-game story played a key role and the situation in the game reflects events depicted in the novel of the same title by Tony Gonzales. The expansion allowed both individual players and whole corporations to fight for the four major NPC Empires of New Eden and battle for control of regions of space.

=== Quantum Rise ===
Release date: November 11, 2008
The Quantum Rise expansion included features such as a new certificate system that allows verification of a player's proficiency in certain defined groups of skills by other players and a medal system for awards by corporations. Industrial ships were rebalanced and optimized, with addition of the Orca-class ship, "a sub-capital logistical ship with a mining command focus." The staged delivery of the expansion began with the recent implementation of new technology such as StacklessIO and EVE64 which upgraded the server hardware and streamlined communication between server and client to reduce lag. These improvements provide performance allowing for player vs. player battles with thousands of participants. Further hardware and software improvements are planned. Other features of the expansion include further graphics updates as started in the Trinity expansion; the ability for players to group their vessels' weapons for easier interaction; changes to autopilot routes and avoidance of player-defined solar systems.  This patch also brought a controversial overhaul of the speed system.

=== Apocrypha ===
Release date: March 10, 2009
At Fanfest 2008 it was announced that instead of a six-month gap between expansions the subsequent expansion to Quantum Rise, Apocrypha, would be released on March 10, 2009. This expansion included a training queue, Tech 3 vessels, and exploration of uncharted space through unstable wormholes. Apocrypha has improved NPCs' artificial intelligence and has added a new NPC faction to the game, the Sleepers.Apocrypha 1.5 was released on August 20, 2009 and considered by CCP to be a mini-expansion. CCP felt that Apocrypha was released very early for a Summer expansion, and that they had enough content ready to go for it to be classified as more than a patch. The new mini-expansion brought to EVE four more epic mission arcs, new rig sizes, specialized cargo bays for specific ships, and performance enhancements for their Factional Warfare.
Apocrypha ended official support for Linux operating systems.

=== Dominion ===
Release date: December 1, 2009The focus of Dominion, the 12th expansion, is an overhaul in the alliance warfare sovereignty mechanics. It also includes the introduction of pirate epic arcs, an artistic redesign of planets and a social networking platform called COSMOS (previously called New Eden). Dominion updates the In Game Browser (IGB) with Awesomium (a browser toolkit based on Chromium), allowing the IGB to behave more like a true browser and properly render HTML, javascript and stylesheets.

=== Tyrannis ===
Release date: May 26, 2010
Tyrannis is the 13th expansion to EVE Online, and focuses heavily on planetary interaction. Players are able to take advantage of deposits of minerals and other raw materials found on the planets of EVE. To that end they are given the ability to build infrastructure for harvesting, storage and processing of these materials.
The previously revealed out of game community site allowing players to interact, organize and communicate with each other through a regular web browser has been renamed EVE Gate. EVE Gate features EVE Mail, in and out of game calendars and contacts and updates for players, corporations and alliances.CCP added hundreds of new landmarks throughout New Eden. These are points in space connected to past storyline or player events. The landmarks show up in the overview, making them more apparent and accessible than before.
The Scorpion-class battleships received a graphical overhaul featuring improved quality textures, unique detailing for each model setting them apart from the other variations. The expansion also focuses on other optimizations and improvements throughout the game, such as reducing fleet lag and load handling.

=== Incursion ===
Release Date: November 30, 2010
Incursion was announced on September 21, 2010. The expansion featured the "escalating attacks of the deadly Sansha's Nation". Players are able to join public fleets and co-operate to repel the Sansha incursions, receiving bounties and earning loyalty rewards. Incursion also includes many improvements as suggested by the CSM, as well as hardware upgrades, software improvements and new cluster components aimed at increasing game performance.
Additionally, the character creator was updated with CCP's Carbon character technology for new pilot portraits. Finally, CCP added a Sansha Mothership, the Revenant, Fighter-bombers, the Noctis salvaging vessel, improvements to NPCs and their AI, new loot and rewards,  storyline events and a more  dynamic and simplified system for Planetary Interaction. The web-based social networking platform, EVE Gate, and the official forums received updates in the Incursion expansion as well.
CCP released the Incursion expansion in three phases: a first-step patch with a collection of player-requested improvements on November 30, a second-step patch with hidden features before December 25, and a third-step patch that included key features of the expansion (Incarna Character Creator, Sansha Incursions) on January 18, 2011. CCP has stated that this method of implementation prevents numerous bugs from infiltrating the code, and the key features "will benefit greatly from an additional level of polish."During the second-step patch the learning skills were removed. Players were reimbursed in two ways, they got their invested skill points back which they then could redistribute to their liking or, when they hadn't already inserted the skillbook, they got the NPC price back.

=== Incarna ===
Release Date: June 21, 2011
Previously known as 'Ambulation' and 'Walking In Stations', the overall Incarna feature revolves around allowing players to leave their pods and walk around in their station HQ. Currently 'face to face' interactions with other pilots is not possible. This feature has been in development for the majority of the life of Eve. The first phase of Incarna was released on June 21. 2011.In the initial Incarna release all Captains Quarters were of Minmatar design. The captain's quarters are a private single player environment to introduce players to Incarna. As with the previous expansion (Incursion) this expansion will follow a segmented roll out. This allows for testing of each major feature under the stress of the live server separately.
Incarna also included a major visual revamp of all turrets, mining lasers, tractor beams and salvagers design and animation (including the firing animation).One of Incarna's changes, the introduction of the "Noble Exchange" (NeX) as an in-game market allowing players to buy vanity items, received negative reaction from players and prompted in-game riots.

=== Crucible ===
Release date: November 29, 2011
The Crucible expansion was introduced to refine the existing game aspects. New nebulae graphics, an improved UI, time dilation and gameplay balancing were included in the expansion. CCP also added a line of third tier battlecruisers, which can fit battleship weapons, and the remaining Captain's Quarters for the Amarr, Gallente, and Caldari races. In addition to this, the engine trail effect was reintroduced.

=== Inferno ===
Release date: April 24, 2012 (Pre-Release background enhancements), May 22, 2012 (Full release)

Release date: December 4, 2012
Retribution brought a revamped bounty system, a new "crimewatch" system, added 4 new destroyer ships and a new mining frigate, re-balanced the frigate, cruiser and destroyer ship roles and improved enemy AI.

Other in-game events during the quadrant, such as the Skilling Spree and Skilling is Just A Means, encouraged players to engage in PvP and PvE rewarding efforts with skill points.

PvP was encouraged in low security space through increased loot drops and faster warp speeds, this event bridged into the second quadrant.

=== Invasion Chapter 3 ===
Release date: 26 May 2020

== Changes to expansions ==
On May 6, 2014 at their yearly Fanfest convention, CCP announced the move from the current development cycle of two expansions per year, to ten expansions per year on a rapid release cycle of six weeks per expansion. In September 2015, CCP announced that while the five-week release cycle would be maintained for content such as quality of life changes, ship balance changes, visual upgrades, new ship skins and storyline developments, they would also be bringing back expansions:An expansion will be a set of big, connected features that both make impactful change on EVE, and make a statement about what kind of game EVE is. Second, there won't be a fixed number of them per year, but rather we will announce when we have one in the making and what the main features are.
In early 2020 CCP Games announced they would be splitting the EVE Online year into four quadrants. Each quadrant would have an overarching theme associated with it that allowed for releases, events, offers and more to exist within a given theme for that period of time. Each Quadrant would contain seasonal events, balance changes and game health improvements, permanent meta changes, challenges and rewards that could be themed, for example, around a particular style of gameplay, or any aspect of EVE. The name of the first quadrant for 2020 was 'Fight or Flight' and was themed around PvP.
