Well this thread confirms one things, after a new release wait for all the bleeding edge users to update first

Thanks guys learnt a lot (and still am) about the update process.
I do agree though that the devs should have had a notice at the 1.2.3 download AND in the readme about the ZenPage integration - not everyone uses svn or goes to the ZenPage project page or where ever that notice was supposedly detailing this - the notice should have been with ZenPhoto not ZenPage.
I also agree that while ZenPage is being made an 'official' plugin it should be set as 'NOT' required for ZenPhoto to run and even have it setup as default as not enabled. Please don;t get me wrong ZenPage is great and I use it, but at the same time there are many that do not need it and ZenPhoto has been great for so long without it - so why does it 'NEED' it now?
