Hello,
On Friday of last week, the Wikimedia Foundation's iOS team pushed a new version to our beta channel[1]. During this testing we discovered a regression with tapping images in articles, and have just pushed a very slightly updated version to TestFlight.
This is our release candidate build for version 5.0.5, and barring any issues we plan to submit this update to the App Store early next week.
As usual thanks to our volunteer testers for the help and feedback,
Josh Minor
