Bukkit

Built with spigot 1.21.4

AnvilGUI updated to work with 1.21.4 (Dropped 1.20)

Iconmenu textured heads changed to work with 1.21. The heads by "name" works only on Online servers (online-mode=true)
textured heads base64 dropped in favour of the same stuff, but now they works with the minecraft url directly, or you can just put the url id there.
Example : http://textures.minecraft.net/texture/ "USETHISID"

Fixed a problem that prevented MyCommand to complete the loading if ProtocolLib wasn't loaded successfully.

Fixed a problem with (old base64) custom texture in icon_menu player heads in 1.20 servers.
Added $actionbar$ in RUN_COMMAND (supports hex colors)
Iconmenu fix.
placeholders_replace_mode was missing NO_REPLACE and NO_PLACEHOLDER_API

PlaceholderAPI replacer feature : //%mycommand_replacer_<var_name>%
Use the command /mycmd replacer or manually directly in the config file as example :

othersdb.yml:

placeholder_replacer:
 wgemptyarea:
  placeholderapi: worldguard_region_name #Do not use % prefix and suffix.
  replace_if: ""
  with: "Wildness"
