+# Minimum Support Rust Version (MSRV)
+
+hyper's current policy is to always support a Rust version at least 6 months
+old. That is, a compiler version released within the last 6 months can compile
+hyper. It is possible that an older compiler can work, but that is not
+guaranteed. We try to increase the MSRV responsibly, only when a significant
+new feature is needed.
+
+The current MSRV is: **1.46**.
