docs(ref): Expand on MSRV by epage · Pull Request #14636 · rust-lang/cargo (original) (raw)

What does this PR try to resolve?

The need for this has been growing and becomes especially important with the upcoming MSRV aware resolver
We will be making having an MSRV easier so we need to meet those maintainers where they are and help them.

In particular, this covers

• What setting an MSRV does
• What "support" in MSRV means, according to the definition we developed during the review of RFC 3537
• Background and guidance on setting an MSRV policy

How should we test and review this PR?

Additional information

This intentionally leaves out anything related to the MSRV-aware resolver as that will be handled as the feature is stabilized.
