Hi, since trunk of FILEUPLOAD has breaking changes, I'm not going to create a RC until we have resolved/come to an conclusion about this. The easiest way to fix this is to readd java.io.Serializable to the classes where it has been removed.
I'm going work on a release of the stuff which is currently in the b1_3 branch. Since the branch introduces new functionality, it is really 1.4 and not 1.3.3. For this reason, I'm going to rename b1_3 to b1_4. Please let me know if you see a problem with this proposal. BR, Benedikt
