v0.1.0

First release, for Minecraft Bedrock Edition 1.26.51 and LeviLamina 26.51.7 (Windows x64).
There are two builds: server for BDS and client for the game. Every player needs the client
build, in single player and on a server.

Added

• Six backpack tiers: Leather (27 storage / 1 upgrade slots), Copper (45/1), Iron (54/2),
  Gold (81/3), Diamond (108/5) and Netherite (120/7), with Sophisticated Backpacks' recipes, tier
  upgrades and dyeing.
  • Contents belong to the backpack, not to the player, and are stored in the world itself.
  • Backpacks can be worn, placed in the world, opened from another player's back and linked with
    the Ender Linker.

    transfer buttons, abbreviated counts, memory and no-sort slots;
