+## Minimum Supported Rust Version (MSRV)
+
+Changes to MSRV are considered breaking changes. We are conservative about changing the MSRV,
+but sometimes are required to due to dependencies. The MSRV is:
+
+  * 1.42.0 for the `read` feature and its dependencies.
+  * 1.56.1 for the `write` feature and its dependencies.
