ROS 1.1.2 Released

ROS 1.1.2 has been released. This is an unstable release to test new features for ROS.

The major new feature with this release is integration of roslisp. roslisp is a full-featured Common Lisp client library for ROS that is being developed by Bhaskara Marthi (Willow Garage) and Lorenz Mösenlechner (TUM). We are now including it in the ROS stack to enable you to more easily access its capabilities, especially in shared install setups where ROS messages have already been built.

This update does not require ROS users to install Lisp. We have created a separate "roslisp_support" stack with a "roslisp_runtime" package that will trigger an install of SBCL, when required. Current users will have to make sure to add a dependency on the roslisp_runtime package so that installation scripts work properly.

Another major update in this release is performance updates for rospy message serialization. The new optimizations should result in performance improvement of 2x or better for many types of messages, mainly thank to James Bowman's patches.

As with our previous unstable releases, we ask that general users refrain from updating to this release unless they need to test integration for the upcoming C-turtle distribution. We do recommend that roslisp users test this new setup and provide feedback on this new roslisp core integration.
