Build 10586.29 of Windows 10 for Mobile is now rolling out to Insiders on Fast Ring. This build doesn't bring any new features but the general improvements and bug fixes. However, this build marks the beginning and is the first Cumulative Update to the Windows 10 Mobile that begins addressing the feedback Microsoft has received since the past build, 10586.
The blog post reads:
We have received a lot of useful feedback from our Insiders on our last Windows 10 Mobile Insider Preview build 10586. While this is the same base build that we are shipping with new Windows 10 devices, we are continuing to address feedback on the upgrade experience from Windows Phone 8.1 as reported from Windows Insiders.
Today we are releasing our first Cumulative Update to the Windows 10 Mobile Insider Preview Build 10586 to Insiders that begins addressing this feedback. The first thing you will notice with this Cumulative Update is it will use the minor version for differentiating between each version as these builds only contain fixes to the Windows 10 Mobile Insider Preview build already in the Fast and Slow rings. So this build will appear as 10586.29.
Here are the improvements Microsoft has brought to this build after receiving the valuable feedback.
- Data profiles are now correctly restored in the out of box experience that would prevent some devices from sending or receiving MMS messages.
- We have resolve issues on switching the active cellular connectivity profile on Dual SIM devices.
- Additional Bluetooth stability improvements.
- Edge performance and stability has been improved. Auto-completion has been updated to allow user to more easily edit the end of the URL in the address bar.
- Improved application backwards compatibility for Windows Phone 8.1 Silverlight applications.
- You will see additional improvements in upgrade experience, including devices with limited free space, map rendering on update, and RCS enabled device settings.
If you are already an insider, you don't need to do anything except heading to settings>update & recovery>phone update to check for updates and grab it.
