 Bitcoin Electrum client library. Supports plaintext, TLS and Onion servers.
 
 ## Minimum Supported Rust Version (MSRV)
 
-This library should compile with any combination of features with Rust 1.63.0.
-
-To build with the MSRV you will need to pin dependencies as follows:
-
-```shell
-cargo update -p rustls --precise "0.23.19"
-```
-
+This library should compile with any combination of features with Rust 1.75.0.
