From old version to new version the value in the stream is discarded. From a new version to the old version, the value in the stream is missing so the field is initialized to its default value (false for boolean). There's no reason to change the serialVersionUID. Changing it would be an incompatible change and cause all kinds of other problems.

Thanks for the comments, just want to be sure the old version handles the missing field, that's all.
