Microsoft offered a new version of Windows 10 Mobile to the earliest adopters in the Windows Insider Program on Thursday, accelerating the release of new beta versions of its mobile operating system.

Build 10149 offers a number of improvements for people brave enough to install it on their devices, including a new button in the Action Center that turns on a phone’s flash so that it can be used as a flashlight. Cortana’s Notebook user interface has been finalized as well, with a combined profile and settings page.

The new build, which went out to users in the Fast ring of the Insider Program, also includes branding for Microsoft Edge, the new browser that the company previously included under the Project Spartan code name. That update also moves the address bar to the bottom of the screen and allows users to request either the mobile or the desktop version of a website. The browser has been given a new app ID to go along with its new name, which means users will lose any favorites, cookies, history and saved Reading List items after upgrading from a previous build.
