 ## Minimum Supported Rust Version (MSRV)
 
-This library should always compile with Rust **1.57.0**.
+This library should always compile with Rust **1.63.0**.
 
 To build with the MSRV you will need to pin the below dependencies:
 
 ```shell
-# log versions at 0.4.19+ have MSRV 1.60.0
-cargo update -p log:0.4.19 --precise 0.4.18
-# tempfile versions at 3.7.0+ have MSRV 1.63.0
