Backpacks!

Sorry for not updating this datapack in a while, a lot has happened since the last update, but at least here's the first major update for it, enjoy!

• (v1.2)
  • Fixed:
    • After uninstalling there were some errors in the logs due to certain advancements that weren't being revoked (#16).
    • You could put the backpack inside itself sometimes (#7).
    • Backpack duplication when unequipping it from the offhand (#18).
    • You could unlock all slots from the last page of a backpack when opening it when it was closed in the last page.
  • Added:
    • Now supports 1.21.3!
    • Now you can see what version you are using when doing /reload.
    • Added planet minecraft link to the /reload message.
    • Added the first setting of the datapack, Blacklisted Items.
    • Function to see all aviable settings.
    • Added two new styles to the normal backpack (Autumnal and Christmas styles) and added the first style to the ender backpack (Ender Dragon style).
    • Portuguese brazilian language by alexsanderfer (some translations are missing due to the new content addded).
  • Changed:
    • Now the menu doesn't show its name in third person (thanks to Evtema3 for his shader and for helping me personally use it <3).
    • Now uses AmberWat's Negative Space Font for hiding the name of the menu in third person in Evtema3's shader.
    • Now the backpack menu supports most custom resourcepacks that changes GUIs.
    • Better performance.
    • Now you can't get the World of Color advancement by applying a style to a Backpack.
