 ## Minimum Supported Rust Version (MSRV)
 
-This library should always compile with any combination of features on **Rust 1.29**.
-However, due to some dependencies breaking their MSRV in patch releases, you may
-need to pin these deps explicitly, e.g. with the following commands
-
-```
-cargo generate-lockfile
-cargo update -p serde_json --precise "1.0.39"
-```
+This library should always compile with any combination of features on **Rust 1.41.1**.
