 ## Minimum Supported Rust Version (MSRV)
-This library should always compile with any combination of features on **Rust 1.29**.
 
-Because some dependencies have broken the build in minor/patch releases, to
-compile with 1.29.0 you will need to run the following version-pinning command:
-```
-cargo update -p cc --precise "1.0.41" --verbose
-```
-In order to have serde support, the following versions also need to be pinned:
-```
-cargo update --package "serde" --precise "1.0.98"
-cargo update --package "serde_derive" --precise "1.0.98"
-```
+This library should always compile with any combination of features on **Rust 1.36**.
