You read that correctly, the [DEPRECATED] tag was removed. I was messing around with dust cloud textures, and I liked what I saw, so now you get to enjoy it as well!
This resource pack requires StellarView in order to do anything. I reiterate, if StellarView is not present in your mods folder, this resource pack won't do anything.
If you are using StellarView 0.3.0 or 0.3.1, it is recommended that you download v3.
If you are using any version of StellarView 0.3.2 or above (latest tested is 0.4.5), you should use v4 instead.
