The formula for versions in the W3C and most projects in general is:

   - if conformance changes, then increment major version
   - if conformance doesn't change, but new features are present, then
   increment minor version
   - if conformance doesn't change and no new features are present, then
   increment or add micro version; alternatively, add a 2nd, 3rd, etc Edition
   marker

The changes between IMSC.next and IMSC1 are clearly in the second category.
