Microsoft has just released the new 10549 build of its Windows 10 Mobile preview, and it contains a number of improvements and features, including for Cortana and messaging:

Here's what Windows Insider leader Gabriel Aul says what's new in build 10549:

  • Improvements to Cortana: Cortana now works for Insiders in Japan and in English for Insiders in Australia and Canada.
  • Messaging app improvements: The Messaging app now has a text box that can be expanded as you enter text. Previously, the text box had 2-3 lines which made it really hard to see what you were typing. As I mentioned yesterday with Build 10565 for PC, an upcoming build for mobile will include the integrated Skype capabilities for you to preview.
  • Diverse emoji: With this build, we are adding support for Unicode's diversity emoji's. Consistent with Unicode's vision, we're excited to offer people all over the world with emoji that reflect more human diversity. We added this capability to the PC with Build 10547 and now we're extending to mobile. Check out our new diverse emoji and let us know what you think.
  • An update for Lumia 1020 users: Lumia Camera is no longer uninstalled when you update to Windows Mobile 10, so you can continue using it when you update your phone from Windows Phone 8.1. You should use Lumia Camera in order to take advantage of all of the Lumia 1020's great camera capabilities. Lumia Camera is not yet available in the Store for Windows 10 devices so you will need to use the Windows Phone Recovery Tool to return to Windows Phone 8.1 in order to get the app back.
