Major changes in the geography and history of the world take place as Episodes in the Ragnarok Online timeline. As the development team is located in South Korea, this list will consist of updates made to their particular servers for developmental consistency.
NOTE: According to the kRO site, the earliest update utilizing the word "episode" was Episode 2 (featuring Lighthalzen), which doesn't really make sense in the broad scheme of things. Therefore, episode information is cross-referenced from the Korean Wikipedia.

At one point in RO's life, the developers felt that the game had reached its limit in trying to compete with newer and more polished MMORPGs. So in 2008, development began on RO's Renewal, which would change the way everything worked in the game. After about 10 months of testing, RO was renewed on 2009 June 17.
The following compares the more major changes to the game.
|Pre-Renewal (2002-2009)||Renewal (2009 - Current)|
|EXP requirements increased exponentially with each level-up.||EXP requirements increase linearly with each level-up.|
|Cards influenced your attack power directly. (Made 4-slotted Level 1 weapons more desirable than Level 4 weapons.)||Cards that influence your damage now only affect your weapon attack power. (Level 4 weapons became more desirable.)|
|Players were able to achieve instant cast with high DEX and cards.||Most skill casting is now composed of both a fixed cast time and a variable cast time. (The fixed component of the cast time cannot be reduced via stats.)|
|Old formulas made magic users very powerful in battle.||Revamped formulas weakened magic users and buffed melee players.|
|DEF on gears contributed more to decreasing damage received.||DEF on gears are now of little to no significance.|
|Character performance was more stat-dependent.||Character performance became more gear-dependent.|
|Players were limited to 1 hotkey bar when it came to using skills. (Battle Mode alleviated this to some degree, but players could not customize their hotkeys.)||Players can now fully customize all their hotkeys and have the ability to view 4 rows of hotkeys for skill usage.|
|Every monster was unique in terms of stats and difficulty.||Monsters were streamlined to be more homogeneous and difficulty was amped down significantly.|
|No EXP penalty for killing monsters several levels higher or lower.||EXP penalty incurs for killing monsters 15 levels higher or 5 levels lower.|
|No drop penalty for killing monsters several levels higher or lower.||Drop penalty incurs for killing monsters 5 levels higher or 10 levels lower.|
