Datapack does not work well on newer versions. For example, I'm at level Y 94 in a savanna biome and I hear ambient from an abandoned mine. Additionally, of course, the sounds from level 0 to level -64 and from level 254 upwards do not work. Will this datapack still be supported?

Yes the same is happening to my game, are you going to update to 1.19

Last commit was 2 years ago so I'm afraid it's no longer maintained

Hello! Yeah, the data pack has been unmaintained for 2 years. Regarding 1.18 and 1.19 compatibility, I'm coming up with a hot fix since these updates completely broke the pack, although i'm sure I won't be able to recover cave ambience completely because the current method I use to detect if a player is in a cave doesn't work anymore (caves no longer generate with cave_air).

I understand, we will wait for a fix :)

Just released it!

I'm marking this as solved ;)
