The Minecraft launcher keeps logs of game events as they happen which can be useful for debugging errors or other issues that may occur within the game.

The latest log begins logging after Minecraft successfully launches. Sometimes error messages are logged there and are helpful in troubleshooting certain errors and crashes that happen in-game.
