 To build with a particular version of the Rust compiler, pass that version to [`rust_register_toolchains`](flatten.md#rust_register_toolchains):
 
 ```python
-rust_register_toolchains(version = "1.59.0", edition="2018")
+rust_register_toolchains(version = "1.62.1", edition="2018")
 ```
 
 As well as an exact version, `version` can be set to `"nightly"` or `"beta"`. If set to these values, `iso_date` must also be set:
 
 ```python
-rust_register_toolchains(version = "nightly", iso_date = "2022-02-23", edition="2018")
+rust_register_toolchains(version = "nightly", iso_date = "2022-07-18", edition="2018")
 ```
 
 Similarly, `rustfmt_version` may also be configured:
 
 ```python
-rust_register_toolchains(rustfmt_version = "1.59.0")
+rust_register_toolchains(rustfmt_version = "1.62.1")
 ```
