Let's start with the developer (Invoke IT) and his notes on this new v2(.0.5.0):
I mentioned that the design is different – it follows the curated style on the website closely. Not only that I have followed a new style myself – I created this app as an SPA (Single Page Application). With WinRT API page caching is disabled by default and maintaining scroll positions etc is PITA. In past I have seen ListView behaving oddly when page caching is turned on.
To get away from this, I created this app as an SPA. No forward backward navigation – its more like show / hide correct content. It's a big experiment on my side.
There's definitely a feeling that you're interacting with a fluid, almost 'alive' entity when reading through v2.x - and less of a feeling that you're browsing through a web page via a wrapper.
With a SPA, performance will depend on the device being used and its free RAM, of course - for the tech heads, this figure is broken out in one of the Settings screens. I was using Daily Mail Online on a Lumia 950 XL (on Redstone 2) and everything was pretty fluid, with just the right balance of textual layout and images getting 'filled in' as I scrolled.
Here's the new version of the app in action:
You can grab Daily Mail Online for free here in the Store if you have a phone running Windows 10 Mobile.
