Patch

A patch is an official update a developer releases to fix bugs, improve performance, add content, or rebalance gameplay. Live-service games patch frequently, often every few weeks, and each one can reshape which characters, weapons, or strategies are strongest.

Patch notes are the published list of everything a patch changes, and dedicated players read them closely. Balance patches are where buffs and nerfs happen, so a patch can suddenly raise or lower the value of a particular character or item. Tracking patches helps you understand why the strongest picks in a game keep shifting over time.
