Hi, Think I've solved the build version number issue. The release is correct, but the the process/instructions for building a SDK for the framework need to be clearer. In order to run ide/flashbuilder/makeApacheFlexForFlashBuilder.sh you need to compile the source release, but if you're not careful in how you do that ie just do an "ant main" it will regenerate the flex-sdk-description.xml file and set the build version to 0.
Thanks, Justin
