Unfortunately, even this would not have helped much as there is no list of
package that got updated between TW releases - if there is, I'm not aware of it
:(
Such a list would most likely contain more packages than which got updated on
your system as there may have been updates to packages you don't have
installed.

Therefore, the best source for for finding the packages which have changed is
/var/log/zypp/history.

Ok, great! Good to know! Thanks for testing :)
