@kairenw we forgot to advertise the new timestamp_mode TIME_FROM_ROS_TIME option and include it into the release note

whoops! good catch

This doesn't make any sense:

ouster_example/ouster_ros/CMakeLists.txt

Lines 56 to 64 in dc087a3

	catkin_package(
	LIBRARIES nodelet_os_cloud
	CATKIN_DEPENDS nodelet roscpp std_msgs
	)
	catkin_package(
	LIBRARIES nodelet_os_image
	CATKIN_DEPENDS nodelet roscpp std_msgs
	)

There are no targets called nodelet_os_cloud and nodelet_os_image. I guess this will completely break any library depending on ouster_ros because it would be searching for these nonexisting .so files. Also, you call catkin_package three times in the CMakeLists.txt. That is also highly unusual (I even wonder it works).

[peci1]

In ouster_ros, you also have to install the nodelets_os.xml file to the package share destination.

[Samahu]

@peci1 You are absolutely right, we should have revised these statements when we switched from nodes to notelets.
