7 Days: A week of Build-ing excitement, Apple's small wonders and Microsoft's chatbot shock

It's been another busy week across the tech world, bringing some news that had been long-anticipated, and some surprises that were far from expected. With the weekend upon us again, 7 Days is here once more to bring you up to speed on what you may have missed, so get comfy, and let's crack on… We begin this week with bad news for owners of most BlackBerry devices. Facebook has revealed that it will end access to certain APIs on BB OS 7.1 and BlackBerry 10, which means that the next Facebook update for BlackBerry will lose several major features. On Wednesday, Google announced its plans to launch Android Pay in the UK "in the coming months", but while numerous major financial institutions and retailers are onboard, two of the country's'Big Four' banking groups – Barclays and RBS, which includes NatWest – haven't signed up. We've known for a while that the next version of Android would include split-screen multitasking support.
