"summary": "User defined value types with underlying type shorter than 32 bytes used incorrect storage layout and wasted storage",
"description": "The compiler did not correctly compute the storage layout of user defined value types based on types that are shorter than 32 bytes. It would always use a full storage slot for these types, even if the underlying type was shorter. This was wasteful and might have problems with tooling or contract upgrades.",
