Rust Version

1.69 (Dockerfile)

Clap Version

latest

Minimal reproducible code

Our pipelines have started breaking down due to the following error. After investigating, we found that clap crate has been updated enforcing newer rust version we do not use.

 #12 147.0 error: package `clap v4.4.0` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.69.0

Steps to reproduce the bug with the above code

Run cargo build against an existing rust project using 1.69 rust version.

Actual Behaviour

The build pipelines fail despite the fact that we have introduced no change.

Expected Behaviour

Build must stay green for projects relying on older rust versions (compatiblity).

Additional Context

We do not have clap in our toml file.

Debug Output

No response

Our MSRV policy is N-2 which this is in accordance with. In #3267, it was suggested to extend it but that was rejected.

I'm assuming you are not committing a lockfile. For projects that care about MSRV, I recommend you do. If you are concerned with cargo's policy, the cargo nightly documentation removes the discouragement to ignore lockfiles. I'm on mobile right now or else id provide the link.
