As of 1.9.1, the rviz and interactive_markers packages were removed from visualization and made into unary stacks. See their individual changelists for their continuing history.

1.9.2 (2012-11-01)

• Bug fix in stack dependencies.
• Likely last release of Visualization, as it now exists only for backwards compatibility of dependencies.

1.9.1 (2012-10-12)

• Turned visualization stack into a unary-stack metapackage, moving rviz and interactive_markers out into their own repositories. From here forward, changes to rviz and interactive_markers are listed in their own changelist pages.

• Added icons for Displays and changed Display list color scheme.
• Added Python bindings for many of the main rviz classes.
• Changed from texture-based picking to shader-based picking for selection and 3D point finding. The "F" key for focusing the view controller on a 3D point now works for almost all displayed data.
• Selection debugging now publishes images on topics instead of overlaying images on the main display.
• Added status bar at bottom of main window, showing help text for different mouse modes.

1.9.0 (2012-06-04)

• Rewrote Property subsystem. Properties now own their data and emit a signal when that data changes.
• Changed file format from INI to YAML.
• Added ability to put Displays into groups.

• Factored out the templated tf::MessageFilter code used in many displays into a templated subclass of Display to eliminate duplicate code and make it easier to write new displays.
