Flash Player in the Browser support is ending!
Adobe, along with all the major browser vendors (Google Chrome, Mozilla Firefox, Microsoft Edge) have announced that
they will
no longer support the Adobe Flash Player™ runtime at the end of 2020.
If you are looking to output content
to the browser, you should check out our sister project
Apache Royale™

JavaScript and HTML. Apache Flex output to mobile and desktop platforms through the
Adobe AIR runtime provided by Harman
is still supported.
