Upgrading to Flex 3.1
A couple of weeks ago Adobe release a new version of Flex (version 3.1). The new version contains several bug fixes, but also official support for Adobe AIR 1.1 which was also released a some time ago. Upgrading your Flex SDK is not very hard, you just need to download the zip file that contains the new SDK and configure Flexbuilder so that you can start using it. While writing this I am also downloading the Flex4 Gumbo release, and I am looking forward to check it out.
Just follow these steps to install a new SDK in your Flexbuilder:
- Download the new SDK: version 3.1
- Unzip the downloaded file.
- Open Flexbuilder and go to Window > Preferences > Flex > Installed Flex SDKs
- Click "Add..." and point the SDK location to the directory where you extracted the zipfile.
- And now select version 3.1 as your default SDK.
- That's it.
