Feature update notifications

HI All,
We are making a lot of updates to our responsive websites at the moment and i’d like to come up with a good way to notify users of these updates and how they are affected, other than old fashioned notification bars (unless this is the best solution) or blog posts that a lot of users don’t end up reading.

I have seen this sort of thing happen in-app when you open the app post an update and it guides you through what has changed/new features that have been added etc… But i haven’t seen it done so much on websites.

Has anyone seen this done well or done work on this sort of thing and what would you advise?

Many thanks for any advice. Hannah
