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 and support for alternative virtual machines.

This release updates our OpenJDK 7 support to include support for the ARM32 JIT port running on HotSpot 23, meaning ARM users can move to the 2.3.x series. Note: There will be no more 2.1.x releases.

In addition, IcedTea includes the usual IcedTea patches to allow builds against system libraries and to support more esoteric architectures. In this release, use of the system version of LCMS is again enabled by default, but requires version 2.5 or above.

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.
