v2.4-1.21.1

Effective 2.4 (Alpha) - 1.21.1:

As Effective is getting updated to 1.21 and beyond, the mod will move away from Lodestone to instead use Veil.
As a result it requires a big rewrite, and instead of doing one big update, I figured I would do multiple alpha releases as I gradually work on it.

• Replaced the Lodestone library with the Veil library
• All the visual effects using Lodestone have been temporarily disabled until they get rewritten to use Veil. Temporarily removed:
  • Chorus petals
  • Will o' Wisps
  • Allay trails
  • Improved flames
  • Improved dragon breath
  • Underwater chest bubbles
  • Waterfall clouds and mist
  • Fireflies
  • All screenshake effects
• Rewrote splashes and glow splashes
• Fixed inconsistencies with droplets sometimes appearing too far from the splash

v2.3.2-1.20.1

Effective 2.3.2 - 1.20.1:

• Adjusted firefly spawning to be within 5 blocks off to the ground (instead of mostly in the sky like before)
• Added a soft wind ambience to swamp biomes (eg. mangroves being hot made them have no background wind)
• Added a unique mangrove bird ambience during the day
• Changed the cave ambience detection to use solid stone-like blocks above the player instead of light level
  • This fixes some issues that would happen for instance in swamps, where being under a tree and lower than the sea
    level would start playing the cave ambience
• Added a new reverbed foliage rustling sound for lush caves instead of the regular forest one
• Added a check for dripstone cave biomes up to 20 blocks above the player for its ambience
  • This should fix the unreliability of the biome's layout often not reaching the ground where there are no
    stalagmites
• Fixed the ULTRAKILL parry effect missing the white flash
  • The parry effect now uses a direct overlay render instead of Lodestone screen particles
• Reduced the ripple quantity when it rains
• Increased the rain ripple density default config value
• Increased the cascade sound distance default config value

v2.3.1-1.20.1

Effective 2.3.1 - 1.20.1:

• Reworked all audio ambience to make it more dynamic. Different ambient effects will now stack on top of each other
  depending on the environment's properties.
  • Added bees in floral biomes during the day
  • Added birds in forests during the day
  • Added cicadas in savannas during day
  • Added crickets in temperate (excluding swamps to use their dedicated cricket and frog ambience instead) and floral
    biomes at night

  • Added day jungle animals in jungles during the day
  • Added night jungle animals in jungles at night
  • Added owls in forests at night

  • Added mountain wind in peaks
  • Added soft wind in temperate, floral, savanna, jungle and mushroom field biomes
• Split ambient effects into 4 categories (animals, foliage, water and wind) and added volume configuration for each
  • Allows the user to fine tune their audio ambience exactly how they want. If you don't like animal sounds in
    ambience mods for instance, you can completely disable them and keep the rest!
• Changed cascade audio detection to make it so cascades underground can only be heard by players underground, and
  surface cascades can only be heard by players on the surface, to reduce the amount of cascade audio coming from
  underground sources.
