If you’re rocking the Windows Phone 8.1 Preview for Developers, it’s time to update!

Microsoft is now pushing an update out to users running the Windows Phone 8.1 Preview for Developers that bumps the software version up to software version 8.10.14157.200, up from the 8.10.14147.180 update that rolled out earlier this month.

As for what’s included with this new Preview for Developers update, well, that’s still a mystery for now. Microsoft says that the update “can help make your phone work even better,” but it doesn’t elaborate on how it does that. I’ll keep an eye out for any specific changes and let you know if I dig any up.

If you’re rocking the Windows Phone 8.1 Preview for Developers, you can check for this update by going into Settings > Phone update > Check for updates.
