Changelog

All notable changes to InventoryExpansion are documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.4.4] - 2026-06-23

Fixed

• The backpack image shows up again after installing from Thunderstore or Nexus. The release packages did not include Backpack.png, so the backpack panel had no image. The image is now bundled inside the mod itself, so no separate file is needed. You can still override it by placing your own Backpack.png in an "Assets" folder next to the mod DLL.

[1.4.3] - 2026-06-23

Fixed

• Multiplayer: fixed a backpack pickup issue that could make items appear duplicated on clients. The backpack-first pickup runs on the host for every player, but was decided from the local backpack state, so another player's pickup could be redirected based on the host's backpack. It now only applies to your own inventory.

Added

• Large items (the ones you cannot switch away from while holding them, such as two-handed items) can no longer be picked up into the backpack while it is open; a short message is shown instead.
• The backpack can no longer be opened while you are holding a large item.
• New "Block Large Items In Backpack" setting (on by default) controls both of the above. Disable it to allow large items in the backpack again.

[1.4.2] - 2026-06-22

Fixed

• The mod's Harmony patches were applied twice (MelonLoader auto-applies them, and the mod also called PatchAll() itself), so every patch ran twice. The redundant call was removed; patches now apply exactly once.

[1.4.1] - 2026-06-17

Changed

• Started maintaining a full changelog that is now published on GitHub, Thunderstore and Nexus. No gameplay changes compared to 1.4.0.

[1.4.0] - 2026-06-15

Added

• Configurable cursor handoff so the mouse cursor behaves predictably when the backpack is open.
• Backpack-first pickup: picked-up items now go into the backpack slots first.

Fixed

• Corrected the position of durability and stack-count labels on backpack slots.
• Fixed the slot label offset by scaling slots through their local scale, so labels line up at every grid size.

[1.3.1] - 2026-06-15

Fixed

• Compatibility with the Mimesis 0.3.0 game update (avatar detection now resolves again on the new game build).
• The backpack is now hidden during loading screens.
• Fixed the backpack panel breaking after a map change.

Changed

• Pinned the MelonLoader dependency to 0.7.3.
• Refreshed the README with structured content, badges, and detailed configuration options.

[1.1.0] - 2025-11-17

Added

• Movement speed is now reduced while the backpack is open.
• Backpack visibility now respects the game's pause state, and the key hint text was improved.

[1.0.0] - 2025-11-16

Added

• Initial release. Expand your inventory with additional backpack slots and toggle between the standard inventory and the backpack with a configurable key. Includes the backpack image, UI layout, and inventory slot selection handling.
