v0.12.0

What's Changed

New features

• Union directly by @yukinarit in #339

This example works correctly now

@serde
@dataclass
class Foo:
    a: int

@serde
@dataclass
class Bar:
    a: int

bar = Bar(10)
s = to_json(bar)
print(s)
print(from_json(Union[Foo, Bar], s))

However, This will introduce a breaking change!! The default behaviour when you pass Union directly was "Untagged" until v0.11.1, but since v0.12.0 it is "ExternalTagging".

The following code prints {"a": 10} until v0.11.1, but prints {"Bar": {"a": 10}} since v0.12.0

print(to_json(bar))

For more information about Union, please see the docs
