1.6.0

• Release of new package to convert grid maps to signed distance fields.
• Several new grid map filters for flexible processing of grid maps:
  • Math expression filter based on EigenLab,
  • Sliding window math expression filter,
  • Normal vector and curvature filter,
  • Color map, normal color, light intensity filter,
  • ... and more!
• Added new sliding window iterator.
• Added new thickenLine(), triangulation, and bounding box method to polygon.
• Fixed compatibility issue with OpenCV 3.
• Several bugfixes and performance improvements.

1.5.2

• Last release for ROS Jade
• Fixes error in grid_map_rviz_plugin when rendering lines.

1.5.1

• Added backwards compatibility for costmap_2d conversion in grid_map_ros (#111).

1.5.0

• Added new package for octomap to grid map conversion (including demo).
• Added new function for polygon triangulation.
• Added new ROS converter for polygon to triangle lists.
• Moved costmap_2d conversion into a separate package.
• Improved efficiency of mesh conversion.
• Improved visualization to support triangles in all directions.
• Fixed transparency issue for grid maps in RViz. (#68).
• Fixed return value in getQuadrant member function.
• Fixed buffer handling bug for circular and ellipse iterators.
• Fixed bug for change resolution function in OpenCV processing class (including unit tests). (#91).
• Extend grid_map_cv unit test for transparent pixels/nan-values.
• General performance improvements, cleanups, and bugfixes.

1.4.2

• Added conversion for Costmap2D from ROS Navigation (#84).
• Added linear interpolation method for data access (with increased efficiency).
• Fixed conversion to/from images in float&double format.
• Added Grid Map message traits to simplify code of the Grid Map RViz plugin (#87).
• Addressing C++ compiler warnings.

1.4.1

• Added new grid_map_pcl package to convert from PCL mesh to grid map.
• Added functionality to display color from grid map layer.
• Added better handling of basic layers in Grid Map RViz plugin.
• Added functionality to invert rainbow colors in RViz plugin.
• Improved transformation of images to color grid map layers.
• Improved line iterator with start and end positions.
• Added method to retrieve submap size for iterators.
• Improved transformation of images to color grid map layers.
• Fixing issues with order of include with Eigen (#67).

1.4.0

• Added new package grid_map_rviz_plugin to visualize Grid Map messages as 3d surface plots in RViz (height maps).

1.3.3

• Release for ROS Kinetic (also for Jade and Indigo).
• Updated dependency to OpenCV for compatibility with OpenCV 2/3.
• Fixed grid_map_loader demo.

1.3.0

• Separated OpenCV to grid map conversions to new grid_map_cv package. The new methods are more generalized, faster, and can be used without ROS message types.
• Added demos on how to use the new OpenCV conversion methods.
• Several speed improvements and bugfixes.
