+# Changelog
+## [1.8.0 (MONTH Xth, 2026)](#1-8-0)
+
+### Additions
+- Added a new `cobblemon:structure`, which is a feature without any restrictions allowing the Builders to place certain structures in much more specific manner.
+- Added Configs for Infinite Use TMs and Unlocking all TMs
+- Added Type Gem blocks
+- Added Type Gem Clusters
+- Added TMs
+- Added TM Machine
+- Added Deepslate Core Block
+- Added /givetm Command
+- Added Move Dex to Pokedex
+- Added Disk Rack for storing disks and being an audio sequencer for Noteblocks
+
+
+### Changes
+- Data Monitor can accept Disks (TMs, Music Disks, Upgrade, Dubious Disk, etc) to change look
+
+### Fixes
+- Fixed rare Pokémon being far too likely to spawn multiple times in a single spawn cycle. The dev told me that the exact bug is too complicated to explain.
+
+### Developer
+- Tweaked the spawning selector interface to take a bucket function rather than a bucket directly.
+
+### Molang & Datapacks
+
+### Particles
+
+### Localization
+- Updated translations for:

+### Molang & Datapacks
+- Added `moveset_builders` datapack folder for different styles of movesets.
+- Added `party_pools` datapack folder for defining groups of Pokémon for the purposes of complex NPC party definitions.
+- Added `party_compositions` datapack folder for arranging parties on NPCs that rely on party pools.
+- Added `composed_pool` NPC party provider type which combines a party pool with a party composition to create more complex NPC parties.
