Microsoft's essential Windows Phone 7 'Connector' (ironically typo-ed in the official changelog screenshotted below!) for Mac has had an update, adding support for Apple's commercial Aperture browser, ringtone transfer and better video transcoding. Plus the usual small fixes and 13 additional localisation languages. A must-have update if you have a Mac.

Interestingly, I'm not sure I trust the changelog entirely - some of the stated improvements were in previous versions(!), but I'd still recommend updating, just to have the latest and greatest. When you're dealing with phone connectivity, updates and transfers, it pays to stay right up to date.
