## Unreleased

### `aya-ebpf::cty` has been removed. Please use `core::ffi` instead

`aya-ebpf::cty` was a re-export of a crate called `aya-ebpf-cty`.
This crate, which itself was a fork of the `cty` crate, was used to provide
c types for use in bindgen.

Since `core::ffi` contains all of the types we need, there is no longer any
need for `aya-ebpf::cty`. If you were using `aya-ebpf::cty`, you can simply
replace it with `core::ffi`.
