ROS 1.2.2 has been released. It is available now for users of rosinstall or SVN-based installs. It is not available with the debian installs yet.  This release fixes a variety of minor bugs and is mainly being pushed to assist with roslisp integration. Unless you&#39;ve experienced one of the bugs listed in the change list, updating is not expected to be critical.<br>
