Netflix has rolled out a new update to their Windows Phone app. The app includes several fixes and improvements and support for the app in almost fifty new countries.

The biggest feature of the new version of Netflix for Windows Phone is its expanded availability. Netflix has been available on Windows Phone devices in the US and Canada since late 2010. As of today, it’s also available in the UK, Ireland, and 47 countries in Latin America. Along with the expanded availability, Netflix for Windows Phone adds localized user interfaces for all of the countries in which the app is available. It also adds subtitles, closed captioning, and alternate audio for all of the new countries.

Netflix for Windows Phone requires Windows Phone 7.5 or better. It’s available as a free download from the Windows Phone Marketplace, though a Netflix streaming subscription is, of course, required.
