This is a problem, IMO. I sure don't need everything shuffled around once a year.
My experience is that things got worse from v10 to v11... then I read many people saying v7 was better than v8, v8 was better then v9, and v9 was better than v10. This is not encouraging.
I work in software, so I'm not stranger to designers getting tired of their software and wanting to "freshen things up", however users do not want that. Users spend time and energy getting familiar with the software, and no one wants those efforts discarded.
I'm happy for an update when it includes a bug fix or a new feature. Otherwise, meh... who moved my cheese? (yells at cloud)
