Microsoft (MSFT) plans to release the next major update to its perpetually emerging Windows Phone platform this holiday season, according to a job posting on the company’s website. The listing for “Software Development Engineer in Test – Windows Phone,” which was first picked up by WMPoweruser, clearly states that Microsoft is “targeting the holiday of this year” with its next Windows Phone release, though it doesn’t provide any specific details about what features the new software might include. An earlier report claimed Microsoft is planning two minor bug-fix updates to its mobile platform before this major update is released ahead of the holidays.
