Palm has let it be known that developers will now have early access to any future webOS updates so that they can maintain app compatibility in advance of OS updates that would have crippled apps in the past. This can be a huge headache for developers, costing them time and money. Other platforms already do this — take Apple, for instance. iPhone app developers get early access to software updates, before they reach the public, so that they can provide seamless compatibility for their customers. Kudos to Palm for getting this done!
