[ros-users] ROS 1.1.2 released

[Ken Conley]

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 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.

For more updates in this release, please see the full change list:
