ProbablyBackpacks

What's New in v2.4

- Autonomous Pickup Task (`PickupTask`): Dedicated background task for the Pickup Upgrade that checks a 1.5-block radius around players to collect nearby item drops directly into active backpack storage (smartly skips duplicate work if MagnetTask is active). - Modern Paper & 1.21.4+ Version Parsing: Overhauled VersionUtil with regex matching to support Paper build version strings (e.g., 26.2.build.48-alpha) with automatic fallback to Bukkit.getVersion(). - Robust Item & Component Sanitization: Added multi-layered fallback deserialization in BackpackData to strip unregistered/legacy enchantments and invalid item components cleanly. - GUI Slot Bounds Protection: Added slot boundary safety checks during inventory click processing.

What's New in v2.3

- Netherite Backpack Fire/Lava Immunity: Dropped Netherite Backpack item entities are now fully immune to fire and lava damage, preventing your accessories and stored items from burning up. - GeyserMC & Bedrock Support: Fully integrated automatic Bedrock resource pack extraction and custom mappings injection. - Bug Fixes: Resolved minor model rendering logic loop bypasses on newer server releases.

Changelog: Documentation & Recipe Sync

#### Dyeing System Overhaul Base Colors Refinement: Corrected documentation of maximum colors down to 16 standard colors*. Dyeing Interaction*: Rewrote dyeing instructions to describe dropping dye directly onto the dye slot inside the GUI interface.

Stack Upgrades Integration*: Fully documented the linear stack tier upgrade path (Copper -> Iron -> Gold -> Diamond -> Netherite) with respective storage limits (96, 128, 256, 512, 1024). Utility & automation categories*: Structured upgrades into Utility, Automation, Cooking, and Storage classes for a clearer feature outline. #### Crafting & Ingredients Sync (upgrades.yml Alignment) Upgrade Base Requirements: Updated standard utility upgrades (Crafting Station, Pickup, Feeding, Refill, Compacting, Anvil, Jukebox, Smithing Table, Smelting, Blasting, Smoker) to require an Upgrade Base* in the center grid block. Magnet Recipe Fix: Changed the central ingredient from Diamond to Pickup Upgrade* to accurately reflect its dependency implementation.

ProbablyBackpacks v1.1 – Stability & Quality Update

This update focuses on fixing critical recipe issues and introducing stronger item control to improve server stability and prevent abuse. ---

Fixed

🛠️ Fixed multiple issues in the recipe system* that could cause incorrect crafting behavior and console errors. * Resolved inconsistent recipe registrations and misleading error messages in the console. ---

Added

🚫 Item Blacklist System* A new blacklist system prevents specific items — including custom items — from being stored inside backpacks. Important behavior: Blocking a custom item will not block its base Minecraft item.* * Example: If an upgrade item based on Carrot on a Stick is blacklisted, normal Carrot on a Stick items can still be placed in the backpack — only the custom upgrade item will be blocked. This allows precise control without breaking vanilla gameplay or other plugins. ---

Credits

Huge thanks to Vague Ideas for reporting these issues and helping improve the plugin. Your feedback directly made this update possible. ---
