Downloading iWork 9.2

Thanks for your response Niel, but I'm still confused. Are you saying that what I downloaded today (iWork 9.2) actually did update my existing version although the version numbers didn't change. This being the case, there must be only "under the hood" unseen changes as the versions I have remain identical to what they've always been.

Thanks Niel, I think I understand a little better now. Why I'm still a bit confused is this: I've had iWork '09 on my machine for a year or so, Pages being version 4.2. What started me on this journey was because I saw a notification (July 25 2012) that iWork 9.2 was available for download. I assumed from this that this was a brand new update and thus why I downloaded it. So I'm surprised that what I downloaded I already have exactly the same version on my machine already. Given that, I wonder why this download today didn't tell me that it was already installed instead of running through the install proceedure thereby confusing me.

Also, since installing iWork '09 I've never had software updater ask to install a new version. This would indicate along with the points raised above, that 4.2 is the latest version which has been around for at least as long as I have had it.

Also, I guess the reason why I'm not seeing any changes in the iWorks apps is because I have not yet upgraded to Mountain Lion. Am I correct in thinking this. I've been concerned about upgrading to Moutain Lion just yet, waiting for it to settle in, but is this a needless worry and I should now download ML? It was mentioned to me that Safari is having some problems with ML. Have you heard or seen this?

I very much appreciate you help and advice.

Thanks.
