Changes

For Players:

-Rebalanced trades, making emeralds harder to obtain from coal and repricing undercosted goods and contradictions between villagers.

For Developers:

-The mod has been fully transitioned to a platform for developers (All features can be found in the DATAPACK.md file)

-Richer trade items — tags, count ranges, and item data

-Trade cost/result entries gained three optional powers:

• Count ranges — "count": { "min": 2, "max": 5 } rolls a random amount per offer, instead of a fixed number.
• Item tags — "tag": "c:ingots/zinc" resolves to the first item in a tag, so a trade can say "whatever zinc ingot this pack provides" instead of hard-coding one mod's item.
• Components / NBT on results — attach enchantments, custom names, potions, etc.

-Any trade or building file can carry a conditions array (mod_loaded, item_exists, block_exists, each optionally negated). If the conditions aren't met, the file is skipped.

-Merge control — replace. Trade files now append by default (so any number of packs stack cleanly), with an opt-in "replace": true to fully redefine a profession's trades. Files load in a deterministic, sorted order.

-Data-defined professions (new!). You can add a brand-new villager profession with its own job-site block and trades using only JSON — no Java. Define it in config/dynamicvillage/professions/<name>.json (config, not a data pack, because professions must register before data packs load — a hard Minecraft constraint), add its job site to the acquirable_job_site tag via a normal data pack, and give it trades through the usual trade system.

-Tooling — schemas and a worked example

• JSON schemas for trade, building, and profession files (schemas/*.schema.json) — point your editor at them for autocomplete and validation.
• A runnable example add-on (examples/example-addon/) demonstrating every feature end to end, including a new profession.
