Features and Issues in this release:

Check for new images in the Emulator!

The Microsoft Emulator version now includes the ability to query the Store for updated images and install them. On first run of the emulator, if there are no images installed, it will prompt to download an image. The developer can also choose to check for new images through the File->’Download emulator images’ menu item.

Test existing applications in the emulator on released versions of Windows

The Windows 10X Emulator Image version 10.0.19578 includes a new EULA that no longer requires it to be installed on a Windows Insiders machine. You can now install it on Windows 10 version 10.0.17763 or higher. With released SDKs, developers can use this new configuration to test their existing apps on the dual-screen devices and to enhance their app experiences with dual-screen patterns; taking advantage of TwoPaneView class and leveraging the Wonder Bar with CompactOverlay.

  • Reminder, in order to use the Insiders Preview SDK, developers must setup their environment on a Windows Insiders OS

Win32 apps now participate in the windowing model

This update applies the windowing model for Windows 10X to your Win32 apps running in the container. System-defined window placement ensures that users have a consistent and simplified windowing experience that is tailored and appropriate to a smaller, dual-screen, and touch-friendly device. Some gaps remain and will be addressed in future updates.

Additional details can be found in the RelNotes for the release.
