The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as a PulseAudio sound driver, the ability to build against system libraries and support for alternative virtual machines and architectures beyond those supported by OpenJDK.

This release updates our OpenJDK 7 support in the 2.4.x series with the July 2014 security fixes.

Please note that this will be the *FINAL* release in the 2.4.x series. Users are encouraged to upgrade to the 2.5.x series as soon as possible. There will NOT be a 2.4.x update for the October 2014 security fixes.

If you find an issue with the release, please report it to our bug database under the appropriate component. Development discussion takes place on the distro-pkg-dev OpenJDK mailing list and patches are always welcome.

Full details of the release can be found below.
