* Develop games with ActionScript Efficiently build high-performance games using the ActionScript® language. * Coding Develop games more quickly with Flash Builder 4.7 thanks to advanced code hinting, code refactoring, and quick-assist templates. * Multi-threading Create ActionScript workers easily with a wizard-based interface, updated debugger, and build packaging support in Flash Builder 4.7. * Deployment and testing Efficiently deploy, debug, and profile iOS and Android™ apps via USB and WiFi directly from the Flash Builder IDE. * Code faster Reduce the time from concept to delivery with robust coding tools and comprehensive templates. * Powerful code editing Speed coding through syntax coloring, statement completion, code collapse, refactoring support, live highlighting of invalid references, and interactive step-through debugging. * Code generation Use QuickAssist/Fix to rename and manipulate variables, generate getters/setters and event handlers, organize imports, and more. Use the override/implements feature to define methods from a superclass or interface. * Code templates Use over 100 best-practice code templates (aka snippets) for ActionScript, MXML, and CSS. Review and insert templates using code assist. Create custom templates and import or export them for sharing within teams. *Deliver native experiences Provide a better experience to end users across desktop and mobile platforms. *Mobile application packaging and signing Package and sign applications as platform-specific installer files for upload to application stores. *Native extensions Access the latest platform and device capabilities for iOS, Android, BlackBerry® Tablet OS, Windows®, Mac OS, and Linux®. *Captive runtime Increase install rates and reduce testing costs by bundling the runtime with applications. *Easily debug and test Help ensure a quality experience while reducing testing time with powerful testing tools. *Mobile app debugging Debug and test applications on locally connected mobile devices or a mobile emulator. *Memory and performance profilers Accelerate application performance using memory and performance profilers that monitor and analyze memory consumption and CPU cycles. *Network Monitor Generate a detailed audit trail of all data passed between the local Flex application and the back end, assisting with debugging and performance tuning. *Functional testing support Get support for automated functional testing tools such as HP QuickTest Professionaland FlexMonkey.

* Support for multiple platforms * Boards are detected and listed on “ports list” menu together with the serial port * Drivers and IDE are now signed for Windows and MacOSX * Improved speed of build process * Autosave when compiling/uploading sketch * A lot of improvements of the serial monitor (faster, backed by modern JSSC serial library instead of old RXTX) * Find/replace over multiple tabs * Improved lots of Arduino API libraries (String, Serial, Print, etc.) * Tools & toolchains upgrades (avr-gcc, arm-gcc, avrdude, bossac) * Command line interface * IDE reports both sketch size and static RAM usage * Editor shows line numbers * Scrollable menus when many entries are listed * Upload via network (Yún) * HardwareSerial has been improved * USB has got some stability and performance improvements*SPI library now supports “transactions” for better interoperability when using multiple SPI devices at the same time * Better support to 3rd party hardware vendors with configuration files (platform.txt and boards.txt) * Submenus with board configuration can now be defined * Fix for upload problems on Leonardo, Micro and Yún. * Libraries bundled with Arduino have been improved and bugfixed, in particular: Bridge, TFT, Ethernet, Robot_Control, SoftwareSerial, GSM * A lot of minor bugs of the user interface have been fixed
