 `PR #6027 <https://github.com/ros-navigation/navigation2/pull/6027>`_ renames the ``check_full_path`` parameter to ``stop_at_first_collision`` in both the ``ValidatePath`` BT node and the ``IsPathValid`` service definition. The boolean semantics are inverted: ``check_full_path=false`` (old default) is equivalent to ``stop_at_first_collision=true`` (new default).
 
 Additionally, a new ``max_lookahead_distance`` parameter (default ``-1.0``) has been added to both the BT node and the service. When set to a positive value, only the portion of the path within that distance ahead of the robot is validated, improving efficiency when full path validation is not necessary.

+Nav2 Loopback Simulator converted to C++
+----------------------------------------
+
+`PR #6062 <https://github.com/ros-navigation/navigation2/pull/6062>`_ converts ``nav2_loopback_sim`` from Python to C++ for improved performance and consistency with the rest of the Nav2 stack. This results in roughly a 2x improvement in CPU consumption.
+
+Key changes:
+
+- The ``clock_publisher`` is no longer a separate node. It is now embedded within the ``loopback_simulator`` node. Launch files that previously launched both nodes should be updated to launch only the ``loopback_simulator`` node.
+- A new ``speed_factor`` parameter (default ``1.0``) controls the simulated clock speed (e.g. ``2.0`` for 2x). This parameter is dynamically reconfigurable.
+- New parameters ``publish_scan``, ``odom_publish_dur``, and ``scan_noise_std`` are available.
