BlueJ 4.1.3 released
07 Sep 2018

BlueJ 4.1.3 has now been released and is available for download. This fixes various minor bugs, especially in the Git support. We recommend upgrading.

If you weren’t aware, BlueJ has had Git support since the release of version 4.0.0, as part of our support for Teamworking. You can use this approachable Git interface to develop BlueJ projects with GitHub, GitLab or any other Git provider.

BlueJ is 19 years old
23 Aug 2018

BlueJ 1.0.0 was released on 23rd August 1999, meaning that today is the 19th anniversary of that release. We are pleased that BlueJ has remained relevant and popular over that time period, with usage still steadily growing.

Thanks to all our new users, but especially to all our long-time users – we apologise if this makes you feel old! We are busily working on version 4.1.3, which we expect to be released in September.

    BlueJ moves to a new home: King's College London
    13 Mar 2017

    You may have noticed a new logo appearing on the splash screen for the just-released BlueJ 4.0: King’s College London.

    The BlueJ group was at the University of Kent for the last 12 years, and we have a pretty stable team, with a number of very competent developers who have been with us for a long time.

    From February 2017, most of us have moved to King’s College London, a university in the centre of London. This will be the new home of the project. We will still have a small presence at Kent – Ian will stay there – while Davin, Amjad, Neil and Michael have moved.

    This is an exciting move for us. Development of BlueJ will continue as before. Oracle are, as always, very supportive and are continuing support for our team to make further development and support of BlueJ possible.

    Expect more exciting BlueJ releases to come out of King’s in future!
