Mango developers across the globe now have reason to hunker down and bring their apps up to snuff for Windows Phone 7.5. Microsoft has released version 7.1 of its SDK, which means no more coding with beta tools. In addition to the handful of bug fixes and a final spit-shine to the tooling experience, coders will discover the software has been localized to support nine languages, which includes English, French, German, Italian, Japanese, Korean, Russian, Spanish and Traditional Chinese. Redmond is also taking the opportunity to remind programmers that now is an excellent time to check into the App Hub and cross-submit applications into any additional markets where you wish to sell their wares. You've got the tools, folks, now it's time to make it rain.
