Release notes for several applications, including Photos and Music, reveal that the company modified the applications this week with "updates to support the latest Windows 8 changes." Microsoft's Reader application has also been updated with a note revealing that the latest changes are for the Windows 8 Release Preview. Microsoft revealed some of its Mail changes in a video earlier this week, demonstrating an improved user interface and color change. According to one source, a number of the apps are available internally at Microsoft, but not to Consumer Preview users. The updated applications will be released alongside the Windows 8 Release Preview in early June.
