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 1.12.x and 1.13.x series with the January 2014 security errata and a number of bug fixes.

An update will follow for the 1.11.x series (1.11.15), but this will be the final update for this release series, following the release of the 1.13.x series (see the release policy). Users are advised to migrate to either the 1.12.x or 1.13.x series as soon as possible.

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.
