1.21 server support!

Java 17 requirement

  • See https://docs.papermc.io/misc/java-install on how to update your Java version
  • Even Minecraft 1.8 is mostly able to run on Java 17, although for a better experience you should use a fork that fixes smaller issues
  • Some older versions require the Paper.IgnoreJavaVersion system property to be set (-DPaper.IgnoreJavaVersion=true as a startup flag), but run perfectly fine using Java 17
  • If all else fails, use the Java 8 compatibility builds we provide at risk of not receiving support for issues it could cause - you should not make yourself depend on these too much, they will generally only be updated on releases

Fixes

  • Added new config option to suppress emulation warnings (by EnZaXD)
  • Fixed horse inventories in 1.20.5->1.20.3
  • Fixed llama carpet/horse armor display in 1.20.5->1.20.3 (by EnZaXD)
  • Slightly improved item comparison in 1.20.5->1.20.3 by removing empty tags
  • Fixed sniffer entity data errors in 1.19.4->1.19.3
  • Fixed UPDATE_LISTED player profile update in 1.19.3->1.19.1 (by EnZaXD)
  • Emulate recovery compass using lodestone compass in 1.19->1.18.2 (by EnZaXD)
  • Fixup respawning throwing errors sometimes in 1.19->1.18.2 (by EnZaXD)
  • Fixed display of player heads without ids in 1.20.2->1.20 (by Pantera07)
  • Added missing handling of inlined block states in block state particles (by EnZaXD)
  • Added missing translations in legacy protocols (by EnZaXD)
  • Fixed client side damage on cancelled block placement in 1.11->1.10
  • Small fixes to edge case in data parsing in various versions (by EnZaXD)
