!!update

[grizzled kite]

To update Geyser or Floodgate, shut down your server, run !download geyser or !download floodgate in #bot-spam, and replace your current jar file with the new version from the link.
You do not need to remove or modify your config when updating Geyser or Floodgate.

To automatically keep Geyser updated, you can use a third-party plugin, such as GeyserUpdater.
