Flexibility? From Apple? Well now I've seen everything.
Apple has come under a great deal of fire over the last few years for their decision to keep so many aspects of the App Store review process a secret. Developers, many of whom rely on the store for their livelihood, are often unsure from one day to the next which of their apps will be rejected for seemingly arbitrary reasons. It appears that Apple now intends to but a stop to this.
They've sent out a statement announcing changes in the iOS Developer Program license. All restrictions on development tools used to create iOS apps are now gone, as long as the apps themselves do not download any code.
Apple has also stated that they will be publishing their App Store review guidelines for the first time, so that developers will be able to better understand how apps are reviewed. These are both excellent, sorely needed changes and Apple deserves nothing but kudos for finally implementing them. We could complain about how long this realization took the company to reach but, hey, who wants to live life kvetching?
