Unity 6.6 Alpha Adds Built-in Dictionary Serialization
A Unity 6.6 Alpha introduces built-in dictionary serialization and authoring, addressing a long-standing workflow that often required custom wrappers or serialization callbacks.
Unity says dictionary serialization has historically required workarounds and that the 6.6 Alpha brings a native workflow into the Editor. Because this is an Alpha feature, its behavior and APIs should be treated as subject to change.
Why it matters
For tools and asset authors, native serialization improvements can reduce custom infrastructure and make inspector workflows cleaner. It is still important to isolate Alpha-specific code until the API settles in a supported release.
