The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as 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 2.6.x series with the April 2018 security fixes from OpenJDK 7 u181.

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.
