-### MSRV
-This repo's Minimum Supported Rust Version (MSRV) is 1.46.0.
+See example folders for [`actix-server`](./actix-server/examples) and [`actix-tls`](./actix-tls/examples).
+
+## MSRV
+
+Most crates in this repo's have a Minimum Supported Rust Version (MSRV) of 1.49.0. Only `actix-tls` and `actix-server` have MSRV of 1.54.0. As a policy, we permit MSRV increases in non-breaking releases.
