The app version info (major and minor) is crucial because it's used all over the place to identify files such as XSLT files for conversions and rendering. Made changes to the actual embedded version info, the schema filenames, the XSLT filenames, and the imtSchemaFileName global variable. Actually, this should be derived automatically by the app on startup, since it's just imt_ + Major version + _ + Minor version. Look at making this the case. It'll help prevent changes being missed in future versions.
