The official DISQUS app for Windows Phone has been updated to v1.3. The update mainly brings increased language support (Chinese (Simplified), Portuguese(Portugal), Albanian and Greek) and bug fixes, including no longer losing a comment being typed when you lock your screen and being directed to the mobile version of the DISQUS website to update your profile rather than the desktop version.
More interesting for developers and website owners is that DISQUS will soon release an API which will allow their comments system to be embedded in apps. For everyone else DISQUS 2.0 is apparently in the works, which will be a complete rewrite of the app.
The app is free and can be downloaded from the Windows Phone Store here .
