As before, build 107 is all about bug fixes. We do have a summarised changelog via Microsoft:
We have started rolling out the February cumulative update (10.0.10586.107) for Windows 10 Mobile today. Update availability will start with open market variants and will increase to everyone over the next week as we monitor and ensure quality of the release.
Key improvements in this release include:
- Reliability and stability improvements.
- Bluetooth connectivity improvements with car and other accessories.
- Microsoft Edge improvements to PDF rendering and navigation.
- Improvements for battery usage with Iris Recognition for Windows Hello.
- Update system improvements to fix a situation where some users had phone software updates and app downloads stuck at 0% for extended time periods.
- Change to update system to now require phone to be plugged into a charger when downloading and preparing phone software updates.
- Fix for a problem causing erroneous low storage prompts for some users when trying to download phone software updates.
- Fix for a problem that caused erroneous prompts of Outlook account settings being out-of-date for some users, although account settings had not been changed.
- Fix for a problem that caused some phones to get stuck on BitLocker Recovery screen after a reset.
To get this update on your production (i.e. non-Insiders) Lumia 950 or 950 XL, just head into Settings/'Update & Security' - or wait a few hours and it'll be popped up anyway.
This should also be made available to the Lumia 550, though we don't have a unit here for trying this. Windows 10 Mobile 10586.107 is also looking like a good candidate for over the air updating of existing Windows Phone 8.1 devices - if all goes well then I'd expect Lumia 640 and 640 XL devices to start getting the update some time next week (the leap day February 29th has been tipped), followed by the 735 and 830.
