12.3.3 release (MC 1.20.4)

[12.3.3]

• Items which directly grant experience to the player when used can now be used by Activator Modules (which use a fake player)
  • Experience so granted is dropped as experience orbs next to the router
• Some API improvements, thanks to @Matyrobbrt - no player-visible changes here; intended to ease creation of addon mods
