+Introduction of PoseStampedArray
+********************************
+
+In `PR #262 <https://github.com/ros2/common_interfaces/pull/262>`_ a new message type `PoseStampedArray` was introduced to the `geometry_msgs` package.
+In `PR #4791 <https://github.com/ros-navigation/navigation2/pull/4791>`_, most instances of `std::vector<geometry_msgs::msg::PoseStamped>` have been replaced with `geometry_msgs::msg::PoseStampedArray`. Most notably, `NavigateThroughPoses.action` and `ComputePathThroughPoses.action` have been updated to use `PoseStampedArray`.
+Since `PoseStampedArray` contains a header, the poses are now accessed via `NavigateThroughPoses.poses.poses` instead of `NavigateThroughPoses.poses` or `ComputePathThroughPoses.goals.poses` instead of `ComputePathThroughPoses.poses`. Please update your code accordingly when using these interfaces.
