The ultimate source of patches & addons for Crusader Kings II. More Patch Crusader Kings 2 videos.

• Patches and hotfixes are free updates for Crusader Kings II, though there they are different in purpose: • Patches fix many bugs and/or implement balance tweaks. They are sometimes released alongside a new, major; when this occurs a portion of the DLC's features are usually shipped as part of the coinciding free patch, thus made available to anyone who has the base game. • Hotfixes are very small updates to the game that usually fix only a few bugs and may contain a few changes to the gameplay as well.

Hotfixes are commonly released shortly after major patches to fix any unforeseen bugs that came with the previous update, or independently to fix newly-discovered bugs or exploits. • Note that newer DLCs cannot be activated if you're playing on an older patch version. You cannot activate Conclave if you're playing 2.4.X and older, and you cannot activate Conclave and Horse Lords if you're playing 2.3.X and older. This is more applicable for mods, who have various levels of compatibility with new patches.
