## heroku/ruby ### Fixed - Ruby pre-release verssions like `3.4.0.rc1` now work as expected. ([#372](#372)) - 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](#371))

These were added as a part of the RubyConf hackweek, but I just merged that PR in. Between then and now, I added metadata that didn't include the container attribute.
The attribute is described here: https://serde.rs/container-attrs.html.
I proposed adding it to all structs here heroku/buildpacks#23
