Version 2 Compatibility
Version 2 Network and Version 2 Single will co-exist with older versions of MIDUSS on
the same computer. These older versions are MIDUSS 98 and MIDUSS 4.72
Version 2 Single will not co-exist on the same computer with
Version 2 Network installed either as server or client.
Early Version 2 text output files are fully compatible with later
updates to Version 2. That is, an early output file created in Version
2.00 Rev. 100 will work in Version 2.65 Rev 400 (for example).
A text output file created in a later release (example) Version
2.65 Rev. 400 will work in earlier releases, Version 2.00 Rev 100 for
example, with the warning that any new field data in the newer output
file will not have a suitable location or use in the older release and
so that newer-type data will be ignored. Version 2 introduces the Save
Session feature which is a snapshot of all interactions with MIDUSS.
Sessions are saved in a binary file (with the .bin extension). As with
the text output files discussed above, older Session files are
compatible with updated releases of MIDUSS Version 2. However, a
Session created with a recent Version 2 will be compatible with older
Version 2 releases to the extent that new features (on the new Session
file) cannot be properly assigned in the older release and will be
