微软今天推出了Windows 10 Mobile Insider 15204 版本，本周早些时候版本为15063.138可以更新到15204，这个版本是第一个Redstone 3移动版的内部测试版本，根据Dona Sarkar娜姐解释说，这个版本的核心代码将平滑融合于Windows，平板电脑，手机，IoT，HoloLens，Xbox的核心，当然为了企业用户开发新的客户，微软会继续开发Windows 10 Mobile。
在其他方面娜姐解释说，只有选择设备后，将会正式支持Windows Insider计划，不在列表中的手机将不会正式接收到“创作者更新”，也不会获得Redstone 3 Insider的资格。安慰奖是，不支持的设备仍然可以通过Windows Insider程序得到“创作者更新”不过需要风险自负因为如果你选择安装的话，并不会获得微软支持。
下面是支持列表：
Alcatel IDOL 4S
Alcatel OneTouch Fierce XL
HP Elite x3
Lenovo Softbank 503LV
MCJ Madosma Q601
Microsoft Lumia 550
Microsoft Lumia 640/640XL
Microsoft Lumia 650
Microsoft Lumia 950/950 XL
Trinity NuAns Neo
VAIO VPB051
今天推出的新的预览版15204带来两个小的修复，第一次的Redstone 3可能要比平常的系统稳定性更加糟糕，并不建议使用，下面是完整的更新日志：
Changes, improvements, and fixes for Mobile
We have added a new privacy page to the Windows 10 Mobile OOBE experience that allows you to quickly and effectively make common privacy changes while setting up the device. You can read more about our Windows 10 privacy journey here.
We fixed the issue where the keyboard would sometimes not appear when a text input field is selected in Microsoft Edge.
Known issues for Mobile
For Insiders who have upgraded from a prior 150xx build to this build, the “Add Bluetooth or other devices” Settings page and the Connect UX page may fail to open.
Some users are reporting that pages are constantly reloading or refreshing, especially while they are in the middle of scrolling them in Microsoft Edge. We’re investigating.
There is an issue with Microsoft Edge where you might get into a bad state after opening a new Microsoft Edge windows and screen off with the JIT process suspended.
Continuum will stop working when HP Elite X3 case is closed.
Continuum hangs or renders incorrectly after disconnecting on devices like the Lumia 950. The device screen might stay black when disconnecting from a Continuum dock after screen has timed out normally.
如果您的手机支持在支持列表里，那么您可以在手机设置中检查Windows Update来*载下**此新版本。
