Shifting Wares

• Ported to MC 26.1
• Removed the java API.
• Renamed rule allow_map_reroll to allow_persistent_reroll.
• Arbitrary trades can be marked as persistent in datapacks.
• Duplicate trades are now unlikely to happen, thanks to vanilla now including IDs for every trade.

• Fixed Map Reroll rule being inverted.

• Ported to MC 1.21.11
• Renamed gamerules to be valid identifiers.

Gamerules should be migrated automatically when upgrading an older world. This is handled by the mod, not by minecraft.

• Marked branch as incompatible with MC 1.21.11

• Ported to MC 1.21.9, marked previous branch as incompatible.

• Backported v3 to MC 1.20

• Ported to MC 1.21.5, marked previous branch as incompatible.

• Added a gamerule that prevents forced rerolls when breaking a villager's workstation.

Removed the map cache and its surrounding mechanics. Older maps will no longer be resold, in the sense that they will no longer be unlisted at all, unless they meet the conditions to be fully discarded.

• Fixes #11
• Improves native compatibility with other mods. Custom implementations of map trades will no longer cause unsold maps to be discarded.
• Other mods can now more easily communicate data for other kinds of persistent items, without requiring a dependency on Shifting-Wares.

⚠ Upgrading a world from v2 will cause all cached maps to be discarded, even if they were never sold.

• Ported to MC 1.21.2, marked previous branch as incompatible.
• (+1.21.3) Placeholder trades are back to looking empty, thanks to item_model components.

• Trade cache serialization can no longer be attempted on the render thread.
  In singleplayer, this will improve performances when using Fresh Animations and some other ETF/EMF-dependent resource packs.

• Ported to MC1.21, marked previous build as incompatible.

Notice: With map rerolls, an edge case was found where unsold maps have a chance to be discarded prematurely; see #11. Previous versions of the mod are also affected.

Ported to 1.20.5:

• Map trades caching will prioritize the item_name over the custom_name if both components are present.
• Placeholder trades now display an emerald on each sides, since Minecraft no longer supports empty trades. (The change is purely cosmetic, placeholders still cannot be used.)

Upgrading an older world to 1.20.5

No particular actions should be required, but the upgrade process is partially handled by the mod, please make backups and report any oddities you may find.

The mod needs to upgrade exploration maps from the trade caches. Potential issues to look out for are: trade maps loosing their content, their name, or not being stackable with previously sold maps.

If a villager had an empty placeholder trade, Minecraft will simply delete that trade. This shouldn't cause any long term issue; the villager's trade list will naturally fix itself upon rerolling.
