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 6 support in the 1.13.x series with the July 2016 security fixes from OpenJDK 6 b40.

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.
