Less than a year after Flex 2 was released Adobe hits us with the Flex 3 beta. Flex 3 has a number of improvements including framework caching and profiling. Framework caching will allow us to deploy SWFs that don’t include the Flex 3 framework code. This code can instead be cached by Flash player. Profiling is something that Flash Player that needed for years. This allows us to see what our application is doing under the covers and help us debug performance and memory problems.
