What's new in MORSE 1.3?
========================

General
-------

Components
----------

Robots
++++++

Actuators
+++++++++

- Introduce the new actuator :doc:`user/actuators/arucomarker`, allowing to
  simulate the ArUco augmented-reality marker.

Sensors
+++++++

- The timestamp field is now in seconds instead of milliseconds (`#498 <https://github.com/morse-simulator/morse/issues/498>`_)
- :doc:`user/sensors/semantic_camera` gains two properties (`#396 <https://github.com/morse-simulator/morse/issues/396>`_):
    - `tag` allows to restrict the kind of object you want to detect
    - `relative` returns the position information of the various objects from
      the camera sensor frame (and not the global frame).

- :doc:`user/sensors/laserscanner` gain the possibility to return also a
  remission value at the `rssi` level.
- Introduce the new sensor :doc:`user/sensors/radar_altimeter`, allowing to
  retrieve the distance to the ground.
- Improvement of :doc:`user/sensors/accelerometer`, :doc:`user/sensors/imu`
  and :doc:`user/sensors/velocity`. They now works properly with robots with
  or without physics, and returns properly information in the sensor frame.
  The computation method is configurable using the `ComputationMode` property,
  counterpart of the `ControlType` in several actuators.
- Introduce the new sensor :doc:`user/sensors/barometer`, allowing to compute
  the atmospheric pressure.

Middlewares
-----------

General
+++++++

- Each datastream manager now get an action handler, allowing them to run some
  specific middleware behaviour once by simulation turn.

Socket
++++++

- Socket middleware now accepts the keyword 'port' to specify on which port
  you want the socket binds itself.
- It is now possible to synchronise with an external clock using the socket
  middleware. See the documentation of **time_sync** in
  :doc:`user/middlewares/socket`.

Moos
++++

- Support for Moos has been enhanced, allowing to use multiples Moos nodes.
  Moreover, it supports additional actuators such as
  :doc:`user/actuators/teleport` and :doc:`user/actuators/light`.

HLA
+++

- HLA can be now used as a general purpose middleware, i.e. it is possible to
  import / export any actuator / sensor using the HLA interface. Through, for
  moment, no Simulation Object Model (SOM) has been formally defined for
  Morse.


Builder API
-----------

API addition
++++++++++++

- Add a method ``Environment.configure_stream_manager`` allowing to pass
  option/information to each datastream manager.
- It is now possible to control the mist settings in Morse, using
  ``Environment.enable_mist`` and ``Environment.set_mist_settings``.
