 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:
 
-  * 1.52.0 for the `read` feature and its dependencies.
-  * 1.61.0 for the `write` feature and its dependencies.
+  * 1.60.0 for the `read` feature and its dependencies.
+  * 1.64.0 for the `write` feature and its dependencies.
