Alchemy fixes galore, read the instructions!
- Added Breeze_Rod entries to potions.yml for Awkward potion (see notes)
- Added missing TURTLE_HELMET entry to potions.yml for Tier 1 ingredients
- Added missing Wind Charging potion entries to potions.yml (see notes)
- Fixed bug where mcMMO would attempt to load potions that required ingredients or effects from newer versions of Minecraft
- mcMMO is a little more specific during start up of how many potions it loaded, it will now report on incompatible potions from being on an older game version.
NOTES:
You will have to update your potions.yml manually to receive these changes, it is highly recommended that if you haven't customized this file that you simply just delete it, mcMMO will generate a new one on the next start up and it will contain all the missing entries.
If you have customized this file, you can find the "default" version of this file here on the mcMMO github repo: https://github.com/mcMMO-Dev/mcMMO/blob/master/src/main/resources/potions.yml
You can use this file to compare it to your own and make the manual changes needed to get the new entries.
After making the changes to potions.yml (either via deleting it or not...) mcMMO should now recognize the Wind Charging potion and the Awkward potion created from Breeze Rods

- Addeed Open_Eyeblossom to config.yml Bonus Drops for Herbalism
- Added Closed_Eyeblossom to experience.yml for Herbalism
- Addeed Closed_Eyeblossom to config.yml Bonus Drops for Herbalism
NOTES:
A balance pass for Blast Mining is coming, but for now, I've reduced the total bonus drops and clamped the yield ceiling as Blast Mining is a bit too good.

Salvage update, Folia Fixes, and more
- Added Tridents / Crossbows to salvage.vanilla.yml config (see notes)
- Fixed an issue where Folia could have all of its threads lock up effectively killing the server
- Fixed concurrency issue with Folia regarding locale strings
- Fixed concurrency issue with Folia regarding COTW summons
- Updated 'Salvage.SubSkill.ScrapCollector.Stat' to no longer mention luck being involved
- The amount of materials from salvage are no longer luck-based, you will get a deterministic amount based on damage to the item.
- Fixed Ricocheted arrows losing some data after a ricochet
- Changed color of locale strings for 'Repair.Listener.Anvil' to be easier to read
- Changed color of locale strings for 'Salvage.Listener.Anvil' to be easier to read
NOTES:
- Tridents and Crossbows are now in the salvage.vanilla.yml config, you will need to either delete this config file to regenerate it or add the entries manually.
- You can check the default config file after running this mcMMO update at least once in the defaults folder at plugins\mcMMO\defaults to see what you would need to add if you want to take the manual approach

Big Optimizations and Fishing error fix!
Fixed errors when Fishing or using Shake ability
Significant optimizations made to reading new chunks for mcMMO
Significant optimizations to most block interactions in mcMMO code
Fixed a horrendous edge case where Tree Feller could cause a lot of lag
Notes:
Part of this update focused on optimization, there's improvements of around 30% in CPU time for most code involving block interactions in mcMMO, which happens to be most code in mcMMO.
One of the optimizations made in this update removes an edge case where Tree Feller could cause a lot of lag, but the optimizations really are across the board in regards to any abilities that interact with blocks.

1.21.3 Compatibility!
- Compatibility with Minecraft 1.21.3
- (API) add causingPlayer to McMMOReplaceVanillaTreasureEvent and update Fish Event to use it (thanks bobcat4848 and Jacob Cuomo)
Notes:
Tested this version of mcMMO against 1.21.3, 1.21.1, and 1.19.4, which should be full coverage for all the changes, but it is possible you will run into things I didn't catch.
Please report any errors or bugs on our GitHub issues page if you find them.

Alchemy and Roll Fixes
(Codebase) Reworked Roll implementation (See notes)
(Codebase) Added unit test coverage for Roll
Fixed Alchemy error spam in mcMMO potion matching logic (see notes)
Fixed Alchemy NPE when brewing finishes
Fixed a bug where Roll was modifying damage unnecessarily
Fixed blast mining trying to drop non-items (thanks IAISI)
NOTES:
I'll need to rework Alchemy config logic a bit further to address some issues I've found, for now mcMMO will ignore harmless matching errors in the potion matching logic.
The code for Roll was a bit of a mess, I've rewritten a good chunk of it and added some unit test coverage.
I will likely put out another update for Acrobatics in general, as the code for Acrobatics is whack.
This would be a good time to suggest changes to Acrobatics on discord.
2.2.019
Sep 2, 2024
Fixes and optimizations
Optimized Alchemy code (thanks MrPowerGamerBR)
Fixed an exception that could occur when shooting entities through worlds (thanks Wariorrrr)
Fixes to en_US locale (thanks BlockMasters617)
Maces, Crossbows, and Tridents skill commands don't warn you that they are work in progress anymore.
Fixed IllegalArgumentException when Rupture would trigger on an entity with illegal state
NOTES:
Maces, Crossbows, and Tridents are still in development, the change to remove the message from the skill command was to reduce the visual noise.
2.2.018
Jul 27, 2024
Probability Fix + Herbalism XP Fix and more!
Fixed a probability bug where certain skills would max out in chance to succeed well before they were supposed to (such as Dodge)
Blast Mining will no longer drop mob spawners (see notes)
(Codebase) Added more unit tests for Probability and RNG
The Herbalism XP gained when breaking certain plants that can grow unnaturally tall vertically (bamboo, kelp) is now capped to the most it could give when naturally grown, this can be disabled in experience.yml
Added 'ExploitFix.LimitTallPlantFarming' to experience.yml
NOTES:
This probability bug was a big oopsie and showed a gap in unit test coverage, I've added that coverage and a bug like this in theory shouldn't happen again.
In a future version I will add configuration for admins to control what blocks are not allowed to be dropped by blast mining.
A setting has been added to disable player-created super tall plants from giving full XP, this is on by default, you can tun it off in experience.yml via 'ExploitFix.LimitTallPlantFarming'
