 ### Fixed
 
+- Ruby pre-release verssions like `3.4.0.rc1` now work as expected. ([]())
 - Layer metadata deserialization to Rust structs is now using `#[serde(deny_unknown_fields)]` this prevents the accidental scenario where metadata containing a superset of fields could accidentally be deserialized to the wrong struct. It's unlikely this is currently happening with the current buildpack, but it's a possibly-observable difference so it's being listed ([#371](https://github.com/heroku/buildpacks-ruby/pull/371))
