- Refactored into nodelets for debayering and rectification.
 
- Refactored into nodelets for stereo processing and converting disparity images to point clouds.
- Support for unsynchronized stereo cameras.
- In PointCloud2, now correctly set is_dense to False. 
 
- Refactored into nodelets for displaying images and color-mapped disparity images.
- New utility disparity_view for viewing disparity images only. 
- stereo_view support for unsynchronized stereo. 
- Now right click instead of left click to save images.
 
- Approximate synchronization option for unsynchronized stereo. <<Ticket(ros-pkg 4691)>> 
- Camera calibration system data structures can now handle multiple size chessboards. <<Ticket(ros-pkg 3681)>> 
- Calibration now requires skew points for both mono and stereo calibration. <<Ticket(ros-pkg 4086)>> 
 
- stereo_msgs moved to common_msgs.
