 # Changelog
-## [1.5.0](#1-5-0)
+
+## [1.6.0 - The Bass Pro Fishing Update (Month Xth, 2024)](#1-6-0)
+#### "Now that there's a fishing mechanic, the mod is actually good!"
+
 ### 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 the Data Monitor, Fossil Compartment, and Restoration Tank. Placed in the correct formation, you can use these to create a Restoration Machine where you can bring fossils back to life.
-- Added 3 variants of Tumblestones, which can be planted near Lava or Magma to grow harvestable Tumblestone Clusters.
+- Added Pokémon (and item) fishing using modified fishing rods - Poké Rods! You'll need a Poké Rod smithing template, a fishing rod, and some type of Poké Ball. Each Poké Ball makes a differently themed rod. Why not?
+- Added Lure Ball functionality, increasing the catch rate of Pokémon that were caught on a fishing rod.
+- Added property chaining support for duplicate CustomPokemonPropertyType elements.
+- Added aspect and unaspect PokemonProperty arguments (which also includes commands such as /pokemonedit, /spawnpokemon, and /givepokemon) to allow forcing or un-forcing an aspect on a Pokémon.
+
+### Developer
+- SpawnCause is now an implementation of SpawningInfluence.
+- Added "forcedAspects" to Pokemon to make it easier to easily add basic aspects to a Pokémon in a way that persists. We already know that everyone is going to overuse this. 
+- Made the Pokemon.aspects setter private. This could technically break sidemods but if you are affected by this then you were using it wrong! Use Pokemon.forcedAspects to fix it.
+
+## [1.5.1](#1-5-1)
+
+### Additions
+- Added unique send out particles for Cherish, Dream, Beast, and Ancient Origin balls.
+
+### Changes
+- Sounds for Relic Coin Sacks have been correctly renamed. Relic Coin Pouches received new sounds for breaking and placing.
+
+### Fixes
+- Fixed a bug in which adding organic material to the fossil tank via right click was adding the full count of the stack currently in hand
+- Fixed a niche issue where some properties of entities were not initialized correctly, causing Pokémon that appeared to be level 1 until you battle them.
+- Fixed Fossilized Drake being missing from the Fossils item tag.
+- Fixed PCStore#resize not allowing PC boxes size reduction.
+
+### Developer
+- Changed SpawnAction#complete to return a nullable generic R (the spawn action result) instead of a boolean. More information this way.
+
+### Data Pack & Resource Pack Creators
+- Added support for MoLang conditions for quirks and poses.
+- Changed the AttackDefenceRatio requirement to StatCompare and StatEqual.
+
+## [1.5.0 - The Ruins and Revival Update (May 12th, 2024)](#1-5-0)
+#### "You're telling me that Mojang has added archaeology to the game? Hmm... that gives me an idea."
+
+### Additions
+- Added 17 ruin structures, where you can find Pokémon-themed Armor Trims and Pottery Sherds, Tumblestones, and more.
+- Added 23 fossil structures, where you can brush Suspicious Sand/Gravel for [Fossils](https://wiki.cobblemon.com/index.php/Fossil). You can add [custom fossils using datapacks](https://wiki.cobblemon.com/index.php/Fossils_File).
+- Added the Data Monitor, Fossil Compartment, and Restoration Tank blocks. Placed in the correct formation, you can use these to create a [Restoration Machine](https://wiki.cobblemon.com/index.php/Resurrection_Machine) where you can bring fossils back to life. Use organic material to fill the tank first!
+- Added 3 variants of [Tumblestone](https://wiki.cobblemon.com/index.php/Tumblestone), which can be planted near Lava or Magma to grow harvestable Tumblestone Clusters.

+- Added visual effects for many Poké Balls when sending out or capturing Pokémon.
+- Added a new send-out ball toss animation that showcases the ball used for the Pokémon.

 - Added support for planting Apricorn trees, berries, and mints in [Botany Pots](https://modrinth.com/mod/botany-pots)
 - Added the hidden "True Vivillionaire" advancement.
-- The "Poké Ball" Vivillon variant is now obtainable by evolving a Spewpa after obtaining the "Aspiring Vivillionaire" advancement.
-- Added dynamic lighting support for any Species or Forms when using [LambDynamicLights](https://modrinth.com/mod/lambdynamiclights) or [Dynamic Lights Reforged](https://www.curseforge.com/minecraft/mc-mods/dynamiclights-reforged), at this time we don't ship with any defaults for this feature but addon creators can make use of this feature.
-- Added 6 Pokémon-themed Pottery Sherds, obtained from ruin structures.
+- Added the [Display Case](https://wiki.cobblemon.com/index.php/Display_Case) block. Use it to display your archaeological findings, Poké Balls, or other items.

+- Added [Gilded Chests](https://wiki.cobblemon.com/index.php/Gilded_Chest), available in all Apricorn colors.
+- Added Relic Coins, Relic Coin Pouches, and Relic Coin Sacks. Gimmighoul might be interested in these.
+- Added Type Gems. These will have additional uses later, so you should start collecting them.
+- Added new held items: Ability Shield, Absorb Bulb, Air Balloon, Binding Band, Blunder Policy, Cell Battery, Covert Cloak, Damp Rock, Eject Button, Eviolite, Expert Belt, Float Stone, Focus Sash, Heat Rock, Icy Rock, Iron Ball, Light Ball, Loaded Dice, Red Card, Shell Bell, Sticky Barb, Smooth Rock, Soothe Bell and Weakness Policy.
+- Added Hisui starters to the starter selection menu. They come inside of ancient Poké Balls.

+- Added various new tags for search-ability and better mod compatibility.
+- Added the [Ability Capsule](https://bulbapedia.bulbagarden.net/wiki/Ability_Capsule) and [Patch](https://bulbapedia.bulbagarden.net/wiki/Ability_Patch).

-- You can now punch grown apricorns to harvest them.
+- Changed the Destiny Knot to be crafted with a Ghast Tear rather than a diamond. We have big plans for the Destiny Knot...
+- You can now punch grown apricorns to harvest them. We saw so many content creators breaking apricorns with their fists that it was making us die inside.
+- The "Poké Ball" Vivillon variant is now obtainable by evolving a Spewpa after obtaining the "Aspiring Vivillionaire" advancement.
 - 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.

+- Density, Season, and Nether biome tags have been moved and renamed within the biome tags directory.

 ### Fixes
-- 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.
+- Re-added the recipe for the Iron vitamin. Well, technically it's a mineral.
+- Fixed Exeggcute and Pikachu not being able to evolve.
+- Fixed evolution priority for Exeggcute and Pikachu regional evolutions. Using a thunder stone on Kantonian Pikachu on the beach will give Alolan Raichu. A second thunder stone would then give Kantonian Raichu.
+- Fixed battle text for the Poison Touch Ability.
+- Finally found Sudowoodo and Bonsly. They were missing spawn data. Same with Drifloon and Litwick. Uh... sorry about that.
 - 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 the bounce animation for Poké Balls being delayed by like, a full second. It's enough to drive you mad.
+- 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 Poké Balls freezing in an open state if you're looking away at the moment that it's meant to close. This actually fixes some other things but it's hard to explain.
+- Fixed thrown Poké Balls technically having no name.
+- Fixed very many issues with Bedrock particle effects. There are probably many more. Life goes on.
+- Fixed Arbok patterns not being as specific in spawning as they were intended to be.
 - 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 Pokémon pathing over snow layers and carpets.
+- Fixed the Sobble line not being able to swim or breathe underwater.
+- Fixed mod incompatibility with [Just Enough Resources](https://modrinth.com/mod/just-enough-resources-jer).
+- Fixed mod incompatibility with [Visual Overhaul](https://modrinth.com/mod/visual-overhaul).
+- Fixed an issue that allowed Pokémon to spawn on rails.
+- Fixed the data set on Pokémon when abilities are given via properties such as in ``/spawnpokemon``.
+- Fixed Pokémon sometimes losing hidden abilities when evolving. This fix will only take effect for newly created Pokémon because of technical reasons that were explained to me but which I then forgot.
+- Fixed capture messages not displaying in battle.
+- Fixed the Illusion ability causing the wrong Pokémon to be targeted in battle. 
+- Fixed battles started with fainted party members causing a soft-lock on defeat.
+- Fixed some issues with eyes in the faint animations of Hitmonlee and Phantump
+- Fixed missing evolution moves, for example Stone Axe for Kleavor.
+- Cleaned up empty evolutions declaration in species data (And no, I'm not listing all 169. No I don't care what you pay me, I'm not doing it).
+- Fixed non-consumable held items being consumed or swapped in battle permanently.
 
 ### 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.
+- Significantly changed the way the properties in PokemonEntity work. This could break some plugins (not in a big way, but changes will be needed for some things).
+- Rebuilt the scheduling API to more clearly force side choices and temporal frames of reference for tasks. The developers say that how it works is cool but I stopped listening.
+- Added dialogue API and data registry. This is powerful, and there is a full example in the Cobblemon mod you can trigger using /opendialogue \<username\> cobblemon:example. The example JSON is inside the data folder of the mod.
 - 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.
+- Made the spawning API capable of non-entity spawning. You can make it 'spawn' commands if you want. Go nuts.
+- Made PokemonProperties.parse more interoperable with Java. Save yourself and stop using 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 or 2 regular abilities and 1 hidden ability.
+- ``Pokemon#rollAbility`` has been added which rerolls for 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.
+- `public_spawns_to_json.py` script has been added to give the powerful spawn.json generator a simplistic UI.
+- Updated Showdown with Gen 9 DLC.
+- Changed mixins to be Java 17 for compatibility level instead of 16, removing a warning from startup logs.

 - 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.
