[+] Added experimental support for 1.20.5 - 1.21.1 The following limitations currently apply to 1.20.5+ servers using StackResize:
If you make damageable items (such as pickaxes) stackable, you won't be able to use the vanilla /give command for that item anymore. /give commands from plugins should work fine.
You can't change stack sizes "on the fly" anymore - changing the coniguration now always requires a server restart to take effect.
