On the weak side, Microsoft's Lumia Icon was removed by the list (for now), as there was an issue with scaling on certain devices (930, Icon, and 640XL) which makes the UI too small to be usable, according to Microsoft.

If your phone is already on the Windows 10 Technical Preview, all you need to do is go to Settings apps > Update & recovery > Phone update > and check for updates.

In addition, an early version of the new Project Spartan browser is available in this release. It uses Microsoft's new rendering engine to give greater interoperability with the modern mobile web, and includes early versions of Reading View and Reading List. For now, Project Spartan is not the default browser, and exists side-by-side with IE11.

Outlook Mail and Outlook Calendar are the new built-in mail and calendar universal apps for Windows 10. These new apps bring a fresh UI, with a toggle to freely move between your email and calendar without returning to the Start screen. Outlook Mail includes customizable Swipe Gestures, letting you swipe right or left to take actions like delete, flag, move or mark as read/unread. Also Outlook Mail leverages the familiar capabilities of Word to create a richer email experience. You can do formatting tricks like inserting tables, adding pictures and using bullets and text. Outlook Mail and Outlook Calendar connects to Office 365, Exchange, Outlook.com, Gmail, Google Calendar, Yahoo!, IMAP, POP and other popular accounts.

Microsoft's new Phone and Messaging apps are also available in this build. The Messaging app has a new visual design. You can also easily upgrade from a messaging conversation to a voice call with one click of the phone icon in the new app bar.

The new universal People app has a new visual design but will continue to be the list of all your contacts across the services you care about such as Exchange, Outlook.com, Gmail, Facebook, etc.

The first preview of Microsoft's new universal Maps app on phone is now available. Maps offers you the features and tools you need to explore and navigate the world. This includes maps, aerial imagery, local search data, and voice guided navigation experiences from both Bing Maps and HERE maps, integrated together for the first time into a single app for Windows.

The updated app switcher mow supports landscape when invoked from an app being viewed in landscape. For large phones like the Lumia 1520, Microsoft has introduced a new grid layout so you can be more efficient at switching between apps.

This latest release also includes bug fixes.
