+## [1.5.0](#1-5-0)
+
+### Additions
+- Added over (number here) ruin structures, where you can find Pokémon-themed Armor Trims and Pottery Sherds, Tumblestones, and more.
+- Added (number here) fossil structures, where you can brush Suspicious Sand/Gravel for Fossils.

+- Added Tumblestone Blocks, a storage block crafted from 9 Tumblestones.
+- Added Ancient Poké Balls, which are aesthetic variants crafted from Tumblestones.
+- Added the Ancient Feather, Wing, and Jet Balls, which fly further than regular Poké Balls.

+- Changed the Destiny Knot to be crafted with a Ghast Tear, rather than a diamond.
+- You can now punch grown apricorns to harvest them.
+- Renamed the "Vivillionaire" advancement to "Aspiring Vivillionaire"
+- Removed the Inferno, Forsaken, Poké Ball, and Void patterns from the Aspiring Vivillionaire advancement.
+- Updated movesets to add Gen 9 DLC moves.
+- Apricorn Sprouts can now be planted directly on Apricorn leaves to create a new Apricorn of the same color.
+- Added tooltips to interaction GUIs to make it clearer what they do.
+- Poké Ball recipes now use tags for their center ingredient, rather than specificied Copper Ingot, Iron Ingot, Gold Ingot, and Diamond, allowing for further datapack customisation.
+- Starter Toast now closes once corresponding button is pressed once.
+- Moved some items in the vanilla Food & Drinks category.
+
+### Fixes
+- Resized Snorlax
+- Re-added the recipe for the Iron Vitamin.
+- Cleaned up empty evolutions declaration in species files (no, I'm not listing all 169 by name).
+- Fixed Exeggcute not being able to evolve.
+- Fixed battle lang for Poison Touch Ability
+- Fixed Cubone not being able to evolve into Alolan Marowak.
+- Fixed Squawkabilly forms not being recognized.
+- Fixed the bounce animation for Poké Balls being delayed by like, a full second.
+- Note blocks now play the correct sound on the Apricorn Plank based blocks.
+- Fixed an issue with transformed parts in posers causing whacky positional issues.
+- Fixed Poké Balls freezing in an open state if you look away when it's meant to close.
+- Adds a translation string name to the Empty Pokeball entity.
+- Fixed very many issues with Bedrock particle effects.
+- Fixed Arbok patterns not being as specific in spawning as they were intended.
+- Fixed Pokémon not avoiding danger at all when pathfinding. 
+- Fixed Sobble line not being able to swim or breathe underwater.
+- Fixed incompatibility with [Just Enough Resources](https://modrinth.com/mod/just-enough-resources-jer).
+- Fixed incompatibility with [Visual Overhaul](https://modrinth.com/mod/visual-overhaul).
+- Fixed an issue that allowed Pokemon to spawn on rails.
+- Fixed the data set on Pokémon when abilities are given via properties such as in ``/spawnpokemon``.
+- Fixed sometimes Pokémon losing hidden abilities when evolving, this fix will only take effect to newly created Pokémon.
+
+### Developer
+- Significantly changed the way properties in PokemonEntity work. This could break some plugins (not in a big way, but changes will be needed).
+- Rebuilt the scheduling API to more clearly force side choices and temporal frames of reference for tasks.
+- Added dialogue API and data registry.
+- Opened up the ItemDropEntry class to allow for it to be extended.
+- Added a new "advancement" evolution variant that takes an advancement identifier and succeeds if the player has the advancement.
+- Made spawning API capable of non-entity spawning
+- Made PokemonProperties.parse more interoperable with Java.
+- Added the ``HeldItemEvent``, this comes with 2 implementation ``HeldItemEvent.Pre`` and ``HeldItemEvent.Post``. 
+- API to support dynamic lighting in any mod that implements this feature has been added to all Species & Forms, see LightingData class for details.
+- Added a Mixin for the BrewingStandScreenHandler to fix the incorrect handling of quickMove in Fabric.
+- Corrections to the ability implementation have been made that make ``Ability.forced`` function as intended and never reroll an ability for a Pokémon, please check your implementations to ensure the corrected behavior is intended for your use case.
+- ``Pokemon.ability`` no longer has a public setter, please migrate to using ``Pokemon#updateAbility``, this handles the ability coordinate storage for you when necessary.
+- ``Ability.forced``, ``Ability.index`` and ``Ability.priority`` have all had their setters internalized, there is no longer any need to manually adjust these migrate to the method mentioned above to handle that process for you.
+- ``AbilityChanger`` has been added to API alongside some implementations, this is subject to change as the ability capsule and patch currently only expect the traditional behaviour in the Pokémon games of 1 to 2 regular abilities and 1 hidden.
+- ``Pokemon#rollAbility`` has been added, this rerolls a legal ability for the Pokémon.
+- `docs/cobblemon-tags` tags and spawn-presets can now be auto-generated from the current tags in the cobblemon mod with the `generateSpawnPresetList.py` and `generateTagList.py` scripts.
+
+### Datapack & Resourcepack Creators
+- The maximum amount of fossils that can fit in the Fossil Analyzer can be adjusted in the config.
+- Custom fossils can be defined using a list of items and the resulting Pokémon. An example of `aerodactyl.json`:
+```JSON
+{
+  "result": "aerodactyl",
+  "fossils": [
+    "cobblemon:old_amber_fossil"
+  ]
+}
+```
+- Fetus models can be defined in `bedrock/fossils`.
+- Fetus textures can be defined in `textures/fossils`.
+- Fuel for the Restoration Machine is registered inside the `natural_materials` folder. To register more fuels, create a JSON file containing an array of objects. Each object supports the following fields:
+  - `content`: Integer containing the amount of fuel to add.
+  - `item` OR `tag`: Identifier of the item or item tag to be inserted.
+  - `returnItem`: Identifier of an item to return to the player after consumption.
+- Added 3 new item tags: `ancient_poke_balls`, `fossils`, and `tumblestones`.
+- Added a spawn rules system to modify general spawning behaviour, see the [wiki](https://wiki.cobblemon.com/index.php/Spawn_Rules) for more information.
+- Added dialogue datapack folder and /opendialogue command.
+- Added the item tag ``cobblemon:held/leaves_leftovers`` this can be used to flag apple-like items that can create leftovers when eaten.
+- You can now add support for dynamic lighting implementations, Cobblemon ships with a default implementation for [LambDynamicLights](https://modrinth.com/mod/lambdynamiclights) and the [Dynamic Lights Reforged](https://www.curseforge.com/minecraft/mc-mods/dynamiclights-reforged), add the following to any species or form:
+```JSON
+{
+  "lightingData": {
+    "lightLevel": 14,
+    "_lightLevelCommentRemoveMe": "Above supports 0 to 15",
+    "liquidGlowMode": "LAND",
+    "_liquidGlowModeCommentRemoveMe": "Above supports LAND, UNDERWATER or BOTH"
+  }
+}
+```
+- Following up on this change ``light_source`` was removed as a possible shoulder effect due to becoming unnecessary and never having had a default implementation.
+- Added the item tag ``cobblemon:ability_changers``, contains the ``cobblemon:ability_capsule`` & ``cobblemon:ability_patch`` by default.
+- Added the item tag ``cobblemon:held/is_friendship_booster``, allows items to give the Soothe Bell effect of a boost of 1.5x Friendship gained, contains ``cobblemon:soothe_bell`` by default.
+
