Although Skip Ahead Insiders did not get a new build yesterday, they did receive an update to the Feedback Hub, which now adds integration for the new Language Community app allowing Insiders to vote for language suggestions for Windows settings and apps from right inside the Feedback Hub app.
Changelog: (translated from Italian)
The new version 1.1708.2431.0, contains the following updates:
- It's now possible to receive notifications of new activities in our feedback (PC and mobile)
- Added integration with the new "Community Language" application (PC only)
- In the Profile> Devices and Tasks section, you can now see the new "Device ID" and "User ID" entries, useful for solving problems with your Windows Insider account (PC and mobile)
- Other corrections and translations (PC and mobile)
As well as the integration of Community Language translation suggestions, the Feedback Hub can now place notifications for different types of activities directly into the Action Center, and notifications for your own feedback.
Although the Community Language app is available to Fast Ring Insiders not in Skip Ahead as well, you won't see the Feedback Hub integrations until the Windows 10 Fall Creators Update is released on October 17 for everyone.
The Feedback Hub update applies to those with Skip Ahead enabled in the Fast ring for PC and Windows 10 Mobile.
