We reported on Insiders build 14342 here, a few weeks ago, now we have a brand new build of the next-gen Windows 10 'Redstone' OS for 'Mobile', for 'Fast' ring Insiders. See below for the Microsoft notes, it's currently installing on our test devices. The lady mentioned in the headline is notable as she's the new 'face' of the Windows Insider programme - Gabe Aul has moved aside to concentrate on what should have been his main role, in charge of Engineering Services, and Dona Sarkar is his replacement.

From Dona:

Earlier today, I tweeted about going and hustling the build team about getting a new build as soon as possible. I am excited to report that we have released Windows 10 Mobile Insider Preview Build 14356 to Windows Insiders in the Fast ring. This build has a good set of fixes I think Insiders will enjoy!

Cortana Improvements

Get notifications from your phone to your PC: Cortana will now surface your phone notifications and critical alerts, including messages from messaging services, SMS or social media as well as missed calls from any Windows 10 phone or Android device to your PC, so you never miss a beat while staying focused on your PC.

NOTE: Android requires Cortana version 1.7.1 or higher. (download here for U.S. and download here for China) Some actions on Cortana forward notifications may not be fully functional yet, including reply from PC (for Windows 10 Mobile). Muting the forwarded Windows 10 Mobile notifications per app will come soon. In the meantime, if you want to stop receiving phone notifications, go to Cortana settings and toggle off “Send notifications between devices”. 

Send a photo from your phone to PC: If you need to quickly transfer a photo from your phone to your PC wirelessly – just ask Cortana “send this photo to my PC” and see what happens. This feature is currently exclusive to Windows 10 phones.

New listening animation: When you tap the mic icon in Cortana, there is a new animation that shows Cortana is listening to you as you speak.

 As you might expect as Redstone heads towards July and a public release, this build is mainly about a mountain of bug fixes:

• We fixed an issue that was resulting in high battery usage when using the Microsoft Health app.
• We fixed an issue where the 75-85% battery icon was not very accurate, and made it look like you had more battery left than you actually did.
• We updated the UI for rearranging Quick Actions in the Settings app to now show a visual confirmation of readiness on press and hold, and to show the other Quick Actions reflowing while you’re dragging the Quick Action to its new spot.
• The Settings app will no longer crash when you are re-arranging Quick Actions resulting in the loss of Quick Action slots.
• We fixed an issue that caused the Brightness Quick Action to appear missing.
• We updated thumbnail generation logic to now only create the small thumbnail automatically after taking a picture, and create a larger thumbnail on demand. This saves SD card space for people who take a very large number of photos.
• We have made improvements to the Glance screen. We fixed an issue that resulted in the Glance screen clock occasionally not being up to date. The Glance screen will now “Always show Glance screen when charging” as the default behavior. And we fixed an issue resulting in Glace screen possibly showing an unexpected and extremely large badge count.
• We fixed an issue where the Alarms & Clock app might not update corresponding to a time zone change, resulting in an alarm going off at the wrong time.
• We fixed an issue where the Camera app wouldn’t launch from the hardware key for certain devices if the Flashlight Quick Action was active.
• We decreased the size of icons used in notifications from 64×64 to 48×48 – maintaining the visibility, while improving the use of space in the Action Center.
• We fixed an issue where the solid black rectangle of the keyboard could sometimes be seen for a second after entering your pin on the Lock screen to unlock your device.
• We fixed a few issues causing the keyboard not to come up with various UWP apps like the Messaging app, Microsoft Edge, and Cortana.
• We fixed an issue where diversity emoji might show up as two characters (emoji and diversity modifier) in certain apps, including Messaging.
• We updated backup logic to also include Start tile transparency percent, so that backups created from Build 14356 onwards will restore preferred transparency.
• We fixed an issue that resulted in PCs failing to connect to the phone’s mobile hotspot with the error “Can’t set up network”.
• We have updated app names on Live tiles to now reflect Ease of Access’ Text Scaling setting.
• We fixed an issue resulting in the Brightness Quick Action not doing anything on certain devices after setting brightness to “automatic” in the Settings app.
• We fixed an issue that resulted in Groove crashing when swiping to open the hamburger menu.
• We fixed an issue that resulted in the Settings app sometimes freezing for a bit when moving a very large number of apps to a SD card.
• We fixed an issue that resulted in Continuum having extremely fast scrolling inertia with certain TVs.
• Fixed an issue where Glance screen might show stale badge counters for a few seconds immediately after Glance appeared
• We have updated the Mobile Hotspot settings page to give clearer error messaging when setting up a hotspot fails due to no SIM being connected.
• We fixed an issue that could result in Reminders not showing up at the correct time after upgrading.
• We fixed an issue that would result in Cortana not showing any results if you started the mic and didn’t say anything, and then typed out the query.
• We improved the reliability of Cortana listening after tapping the mic button.
• We improved the refresh time of Wi-Fi data usage breakdown under Settings > Network and wireless > Data usage so it will more quickly update to reflect your usage when you open the page.
• We fixed an issue where the navigation bar buttons for certain devices might be mapped incorrectly when the phone was locked leading to press and hold on back button invoking one-handed mode, and press and hold on Windows button invoking search.
• We fixed an issue that resulted in not being able to turn off Bluetooth above the Lock screen without entering your pin.
• We fixed an issue where certain apps, such as WhatsApp, were not displaying a detailed status on the Lock screen.
• We fixed an issue where certain games developed for Windows Phone 8.1 might not scale correctly after the navigation bar had been hidden and would result in a black bar at the bottom of the screen on devices like the Lumia 535.

Also listed in the Microsoft post are some known issues.

This build was released during the UK night and I've now installed this release on the editorial Lumia 950. Comments welcome if you have any.

Note that when your phone boots up again, there's half an hour or so's wait while all your third party apps reinstall (or at least re-validate) in the background (they're shown as 'pending' in the applications list), so be patient.

• Bizarrely, many application listings in the new Store client are missing their descriptions - anyone else seeing this?
• I'm still seeing unresponsive system (pop-up) music controls, in terms of resuming playback after a gap of more than a few minutes. I wonder if we're starting to get to the point where a backup and rebuild is needed again?

(Note that this is all for those on the 'Fast' Insiders ring only - if you want to join in the fun then install the 'Windows Insiders' application on your Windows 10 Mobile device and select 'Fast ring' when prompted.)

As per all my recent charts and comments, note that Redstone builds are NOT available for the non-Win-10-approved phones (e.g. Lumia 920). no matter how many times you install the 'Windows Insider' utility and enthusiastically tap the 'Fast ring' entry.... The highest version of Windows 10, even unsupported, for older (mainly x20) handsets is 'Threshold' (the 10586.xxx branch). See my feature on all this if you're unsure where your phone will end up in Microsoft's roadmap.
