It doesn't look to bring with it any major changes, but Apple has just released its latest iOS update, which takes things up to version 6.0.2. According to the company, this one primarily addresses a bug that "could impact WiFi." An issue that, incidentally, has been at the center of a number of previous iOS updates. You should be able to find the update now or in the near future in either iTunes or Software Update on your iOS device.
Update: As MacStories notes, this particular update appears to only be for the iPhone 5 and iPad mini.
