v4.5 - 1.21.9 Compatibility update - October 18th, 2025

Changelog:

• Added Venomous 7 (In OptiFine/CIT, already existed with firmament)
• Now compatible with Minecraft 1.21.9 and above.
  • Due to changes in Minecraft's pack.mcmeta format, this version of the pack will display an incompatibility warning in Minecraft versions below 1.21.5. You can ignore this and the pack will work as expected.
