Package aether has been split into multiple subpackages. The split was needed because Aether as a whole has wide range of different dependencies, but separate modules, like API, are fully usable without any dependencies.

Packages that require or build-require aether will have to migrate to appropriate subpackages of aether. This can be simply done by replacing respective Requires or BuildRequires.

Temporarly package aether has Requires on its all submodules to ease migration, but this will be removed in near future.
