The documentation reads:

The app friendly name has been changes from Project Spartan to Microsoft Edge The package family has been change from Microsoft.Windows.Spartan_cw5n1h2txyewy to Microsoft.MicrosoftEdge_8wekyb3d8bbwe The app user model ID has been change to Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge The file name Spartan.exe has been change to MicrosoftEdge.exe The file name Spartan_edge.exe has been change to MicrosoftEdgeCP.exe”

Keep in mind that while this information seems accurate, WZor also published a number of screenshots of build 10135 and the Windows 10 web browser still carries the “Project Spartan” name with version bumped to 16.10135, which suggests that the build isn’t in its final form.

Among other things, Windows 10 build 10135 includes updates for various built-in apps, including Calculator, Get Skype, Music, Photo, and Snipping tool. Update: Microsoft confirms that Microsoft Edge branding appears on internal builds, which means that we will see it soon.
