Hot on the heels of ROS 1.2.2, ROS 1.2.3 has been released.  It is
available now for users of rosinstall or SVN-based installs.  It is
not yet available with the debian installs, but included some changes
necessary to make the deb-builds possible again.  This release also
fixes a bug in rospack, and adds some rosdeps for Fedora systems.
Unless you release stacks that include symlinks, or are a user of
roslisp in a hybrid deb/source-installed system, updating is probably
not critical.
