+## Minimum Supported Rust Version (MSRV)
+
+The MSRV for *5.0* and newer releases of this crate is Rust **1.65**.
+
+The MSRV for *4.x* releases of this crate is Rust 1.45.
+
+Beginning with the 5.0.0 release, this crate will maintain a policy of supporting
+Rust releases going back at least 6 months. Changes that break compatibility with Rust releases
+older than 6 months will no longer be considered SemVer breaking changes and will not result in a
+new major version number for this crate. MSRV changes will coincide with minor version updates
+and will not happen in patch releases.
