Until now, we have stayed in stable Rust, since it allows forward compatibility. There are some nightly features, though, that can help us improve our control over the code we generate. Nevertheless, all of them are experimental and they might change or even get removed before being stabilized.

Therefore, you should take into account that using nightly features will probably break your code in the future and it will take more effort to maintain it to be compatible with new Rust versions. Nevertheless, we will have a quick look at two new features that are coming to Rust.
