Changes since the Iron release
geometry2
Deprecated headers were removed
In Humble, the headers: tf2_bullet/tf2_bullet.h
, tf2_eigen/tf2_eigen.h
, tf2_geometry_msgs/tf2_geometry_msgs.h
,
tf2_kdl/tf2_kdl.h
, tf2_sensor_msgs/tf2_sensor_msgs.h
were deprecated in favor of: tf2_bullet/tf2_bullet.hpp
,
tf2_eigen/tf2_eigen.hpp
, tf2_geometry_msgs/tf2_geometry_msgs.hpp
, tf2_kdl/tf2_kdl.hpp
, tf2_sensor_msgs/tf2_sensor_msgs.hpp
In Jazzy, the tf2_bullet/tf2_bullet.h
, tf2_eigen/tf2_eigen.h
, tf2_geometry_msgs/tf2_geometry_msgs.h
,
tf2_kdl/tf2_kdl.h
, tf2_sensor_msgs/tf2_sensor_msgs.h
headers have been completely removed.
Return types of wait_for_transform_async
and wait_for_transform_full_async
changed
Previously wait_for_transform_async
and wait_for_transform_full_async
of the Buffer
class returned a future containing true or false
In Jazzy, the future will contain the information of the transform being waited on.
rclcpp
rclcpp::get_typesupport_handle
is deprecated
The rclcpp::get_typesupport_handle
that extracts message type support handle is deprecated, and will be removed in a future release.
Instead, rclcpp::get_message_typesupport_handle
should be used.
See https://github.com/ros2/rclcpp/pull/2209 for more details.
Deprecated rclcpp/qos_event.hpp
header was removed
In Iron, the header rclcpp/qos_event.hpp
was deprecated in favor of rclcpp/event_handler.hpp
.
In Jazzy, the rclcpp/qos_event.hpp
header been completely removed.
Deprecated subscription callback signatures were removed
Back in Humble, subscription signatures of the form void callback(std::shared_ptr<MessageT>)
and void callback(std::shared_ptr<MessageT>, const rclcpp::MessageInfo &)
were deprecated.
In Jazzy, these subscription signatures have been removed.
Users should switch to using void callback(std::shared_ptr<const MessageT>)
or void callback(std::shared_ptr<const MessageT>, const rclcpp MessageInfo &)
.
rclpy
rclpy.node.Node.declare_parameter
The rclpy.node.Node.declare_parameter
