Is java's serialVersionUID completely unnecessary when saving to disk using serialization and then deserializing to a potentially modified class type later?

[Big Chungus]

Nope, kotlinx.serialization ignores that completely

[Justin Tullgren]

so if a class changes between serialization/deserialization this should be fine?

[Justin Tullgren]

Additive changes

[Big Chungus]

as long as new props are either nullable or have default values

[Justin Tullgren]

great thank you!

[ephemient]

depends on the format

[ephemient]

in protobuf format, changes that do not preserve the tag numbers (e.g. re-ordering args without @ProtoNumber) will be incompatible
