Developer Panic has decided to not sell version 2.5 of its Apple Design Award-winning Coda Web development app in the Mac App Store, citing the difficulty of working with Apple’s sandboxing requirements. Apple began requiring apps submitted to, or updated on, the Mac App Store to be sandboxed as of 1 June 2012, forcing many developers to pull their apps from the store, stop updating them, or remove features to comply with the requirements. follow link
