What's new

Minecraft 1.21.11 · Java 21 · Fabric Loader 0.19.3

Artifact: copy_paster-3.4.1+1.21.11.jar

Added

  • /copy x1 y1 z1 x2 y2 z2 — copy a region from coordinates (chat naming; needs copypaster.copy). Works without client keybinds.
  • /copyhelp — in-game command summary for copy, paste, undo, and transforms.
  • /copyblocks <name> [page] — block shopping list (paginated); needs copypaster.copyinfo.
  • Default [ / ] keybinds on fresh installs; one-time hint if keys are still unbound.
  • Web UI import — upload .nbt in the browser (POST /api/structures/{name}); export unchanged (Download .nbt).
  • MIT license — open source under LICENSE.

Changed

  • Web save-after-edit — keeps block entity NBT (chests, banners, skulls) when saving palette/voxel edits.
  • Web download — warns if you have unsaved edits (downloads last saved file on disk).
  • Modrinth release notes — full changelog inline on every upload (no “see CHANGELOG.md” stub).

Install

Pick the JAR for your Minecraft version — server and every player who copies must use the same line:

  • copy_paster-3.4.1+1.21.11.jar — Java 21
  • copy_paster-3.4.1+26.2.jar — Java 25

Requires Fabric Loader 0.19.3+ and Fabric API. Bind [ and ] under Options → Controls → Copy Paster (or use /copy).
