Patch notes are official documents released by game developers to inform players about updates to a game. These updates can include bug fixes, new features, balance changes, and improvements to gameplay. Patch notes help players understand what has changed and how it may affect their gaming experience. Typically, patch notes are published on the game's website or social media channels, and they may also be included in the game itself. Players often refer to patch notes to stay informed about the latest changes, especially in competitive games like Fortnite or League of Legends, where updates can significantly impact strategies and gameplay.
