I'm currently using nightly-2022-02-11 installed through rustup, and have enabled a couple of unstable #![feature(...)]s in my crate. Now I'm wondering if these features have since become stable, so that I can switch back to the stable channel. Something like caniuse.com but for Rust compilers.
I know I can check the changelogs, tracking issues for each individual feature, etc., but I'm hoping there is an easier way. Some matrix like this (data are fictional):
FEATURE ... 1.60 1.61 1.62
array_windows U S S
generic_associated_types U U S
const_fn_trait_bound - U -
...
U = unstable
S = stable
- = not available
Ideally this would cover nightly builds as well.
