This article is timeless and should be accurate for any version of the game.
Patches and hotfixes are free updates for Stellaris, though they are different in purpose:
- Patches fix bugs and/or implement balance tweaks. They are sometimes released alongside a new, major DLC. 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. Patches are named by Paradox after various sci-fi writers.
- 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 are playing on an older patch version. This is also applicable to mods, which have various levels of compatibility with new patches.
