"In this round we’re making another 100 or so fixes and improvements. Most are designed to further streamline the app certification process, address app update workflow issues, and improve site performance overall," Microsoft stated in an official blog post. On top of these 100 fixes, Microsoft is also enabling developer registration in 13 new markets for the Windows Phone Dev Center. These 13 new countries include: Afghanistan, Albania, Andorra, Azerbaijan, Bosnia and Herzegovina, Georgia, Iraq, Kyrgyzstan, Libya, Mongolia, Montenegro, Serbia, and Timor-Leste.
