Do not run this jar in production; copy it to another setup. This is the first build where we split off our upstream, Spigot, and instead apply all of its changes and patches ourselves. From this point on, we will no longer pull all new upstream updates.

See our full forum post for more info on what this means: https://forums.papermc.io/threads/the-future-of-paper-hard-fork.1451/


All of your current 1.21.4 plugins should be 100% compatible with builds after the hard fork, it is only plugins trying to use newly introduced Spigot API that may no longer work with Paper. From now on, they will have to target paper-api instead of spigot-api.

Please report issues to https://github.com/PaperMC/Paper/issues if:

  • you encounter a gameplay issue, error, or crash that didn't exist in previous 1.21.3/1.21.4 builds.
  • you encounter plugin issues that didn't occur in previous 1.21.4 builds (assuming your plugin already supports the server version).
