The Apache Flex community is pleased to announce the release of Apache
FlexJS SDK 0.5.0 and Apache Flex FalconJX Compiler 0.5.0.

Apache Flex is a highly productive, open source application framework for
building and maintaining expressive applications that deploy consistently
on all major browsers, desktops and devices (including smartphones,
tablets and tv).

Apache FlexJS is a next-generation Flex SDK that enables developers to use
MXML and ActionScript to not only create SWFs but also cross-compile the
same MXML and ActionScript to HTML/JS/CSS so applications can run natively
in browsers. The cross-compiled code can also be used in Apache Cordova
(Adobe PhoneGap) mobile applications.

Apache Flex FalconJX is a next-generation MXML and ActionScript
cross-compiler. It extends the next-generation SWF compiler known as
Falcon. Both are contained in the release package and are used by the
FlexJS package to compile SWFs or cross-compile to HTML/JS/CSS.

This is the third release of FlexJS and FalconJX. It is ‘beta'
quality. This release includes some new components, updated integration
with Apache Cordova, a few effect classes, drag and drop support, and an
example that is a port of the old Flex ‘FlexStore' example.

The purpose of this release is to gather feedback about the
features and implementation strategies, and recruit new contributors as we
grow these code bases into an SDK and tool chain that delivers the highest
productivity developing applications that can run in the most places.
These releases may not handle production needs. Expect lots of bugs and
missing features. Please file bugs at:

Apache FlexJS and Apache Flex FalconJX are available in source and binary
form from the following download page:

following url:

Choose Apache FlexJS 0.5.0 and it will create an Adobe Flash
Builder-compatible SDK that uses the Falcon and FalconJX compilers to
generate SWFs and HTML/JS/CSS output. You can also use FDT as your IDE
for developing FlexJS applications. Some folks have been successful
using IntelliJ as well.
