I've known that #RustLang's Cargo has been taught to not update dependencies that it can't use (because they require a newer Rust version), but just learned that it can be told to respect the own crate's MSRV for that:

CARGO_RESOLVER_INCOMPATIBLE_RUST_VERSIONS=fallback cargo update

allows me to utilize this even though my MSRV is so old that Cargo didn't have that feature back then.

Thanks to @epage for pointing this out in the handling of https://chaos.social/@epage@hachyderm.io/116222972779591280.
