When N9 informs me of new app updates available - How can I find out what changed between currently installed version and the update being offered?

The apps are from the Nokia store.

launch Nokia Store, open app, and read changelog. It's very easy, isn't it?

Yes easy but... They said that in bugzilla that these information about Store updates should be come automatically like Harmattan-updates (there was filed bug and they said it is fixed...).

If it was that easy would I spend efforts to post here?
I really am not finding it neither in the update app not in the store app.

Sounds like the OP is getting them automatically, he's just not sure where to find the changelog

I think what they fixed is the notification of the updates, not delivering the change log of the updates. I could be wrong though. To read the change log, I think I go to the store and go to the Applications section, and select the New tab. That's where all the new apps (or new updates to existing apps) in the store should appear. Or, I believe I was also able to access the change log when the update notification appeared on my N9 by tapping on the app name first, instead of the download icon in the update screen.

Can't say for certain that it does behave that way, since I visit the Store everyday anyway. I download and update manually. Just a personal preference.

The changelog publishing is the publisher job. Some apps do have the changelog in descrption, some not.

I have not received a single notice of updates from Store... PR1.2... Not fixed IMO.

I have do received every single notice.

I receive it almost every week. Of course, that DEPENDS if you have any apps that need updating in the first place.
