031 * - Major version should be increased only when the new binary format is neither forward- nor backward compatible.
032 * This shouldn't really ever happen at all.
033 * - Minor version should be increased when the new format is backward compatible,
034 * i.e. the new compiler can process old class files, but the old compiler will not be able to process new class files.
035 * - Patch version can be increased freely and is only supposed to be used for debugging. Increase the patch version when you
036 * make a change to the metadata format or the bytecode which is both forward- and backward compatible.
