-## Supported Rust Versions
-
-Tracing is built against the latest stable release. The minimum supported
-version is 1.42. The current Tracing version is not guaranteed to build on Rust
-versions earlier than the minimum supported version.
-
-Tracing follows the same compiler support policies as the rest of the Tokio
-project. The current stable Rust compiler and the three most recent minor
-versions before it will always be supported. For example, if the current stable
-compiler version is 1.45, the minimum supported version will not be increased
-past 1.42, three minor versions prior. Increasing the minimum supported compiler
-version is not considered a semver breaking change as long as doing so complies
-with this policy.
