1.12.16 (2018-06-19)

• Merge pull request #695 from ros-planning/indigo_675 Fixed race condition with costmaps in LayeredCostmap::resizeMap() (backport #675) LayeredCostmap::updateMap() and LayeredCostmap::resizeMap() write to the master grid costmap. And these two functions can be called by different threads at the same time. One example of these cases is a race condition between subscriber callback thread dealing with dynamically-size-changing static_layer and periodical updateMap() calls from Costmap2DROS thread. Under the situation the master grid costmap is not thread-safe. LayeredCostmap::updateMap() already used the master grid costmap's lock.

1.12.13 (2016-08-15)

• Fixed race condition with costmaps Modifying minx_, miny_,, maxx_, and maxy_ without locking the mutex is unsafe and is a race condition if updateMap is called from multiple threads.
