Microsoft announced an update to its App Hub developer portal, ahead of Windows Phone Marketplace availability in six new markets.

Developers can now submit apps for sale in China, as well as Argentina, Indonesia, Malaysia, Peru and the Philippines. It said it will provide more detail on when customers in these markets will be able to buy apps in the future.

It also noted that apps for sale in China, Indonesia and Malaysia will be subject to “additional requirements” in order to comply with “local laws, regulations or norms.” Content which may potentially be deemed offensive includes: “people in revealing clothing or in sexually suggestive poses; religious references; alcohol references; sexual or bathroom humor; [and] simulated or actual gambling.”

Microsoft said that it has opened the submissions to give developers a “head start on certification.” Taking into account the lack of a consumer store and the additional requirements, the approvals process may take “a little longer” during this early-access period.

The App Hub update also includes “a number of minor enhancements and bug fixes,” including improvements to the payout process, and enhanced reporting to provide additional information on app performance.
