Backward Compatibility

Most models developed under Ptolemy II 1.0.1, 2.0.1, 3.0.2, 4.0.1, 5.0.2 or HyVisual 2.2-beta, 3.0, 4.0.1, 5.0.1, 6.0.2, 7.0.1 and 8.0.1 should run under Ptolemy II 8.1.devel

The MoMLParser includes a list of backward compatibility filters that make certain changes on models when read, handling such issues as actors being moved or renamed and parameter names being changed. The filters themselves are defined in ptolemy.moml.filter. If you have developed your own actors under earlier versions of Ptolemy II by writing your own Java files, you should recompile all your java code with the new release. In theory, copying the .class files should work, but recompiling is safer.
