crossbeam-channel v0.3.9 fails to compile

[RalfJung]

After bumping the rustc-ap-* crates in rustfmt, I get

error[E0432]: unresolved import `crossbeam_utils::atomic`
 --> /home/r/.cargo/registry/src/github.com-1ecc6299db9ec823/crossbeam-channel-0.3.9/src/flavors/tick.rs:8:22
  |
8 | use crossbeam_utils::atomic::AtomicCell;
  |                      ^^^^^^ could not find `atomic` in `crossbeam_utils`

The dependency tree looks as follows:

crossbeam-channel v0.3.9
└── crossbeam-utils v0.6.6
    ├── cfg-if v0.1.10
    └── lazy_static v1.4.0

I was able to fix the build with

cargo update -p crossbeam-utils --precise 0.6.5

Actually turns out that even without bumping anything, rustfmt master with its current lockfile just doesn't build here...?

$ rustc --version
rustc 1.40.0-nightly (237d54ff6 2019-10-15)

rust-lang/rust#65424 explains what is going on: the crate was relying on a nightly feature that got changed.

Duplicate of #434, fixed by 5b5d727 but there is no new release yet.

Is there an eta on a new release? I am a bit hamstrung at the moment.

New version has been published now :)
