+++++++++++++++++++++++++++++++++++++++++++++

Documentation
#############
- Replace enthalpy starting value with :code:`state` keyword in the
  :ref:`heat pump tutorial <tespy_tutorial_heat_pump_label>` and the examples from the
  oemof_examples repository
  (`PR #214 <https://github.com/oemof/tespy/pull/214>`_,
  `743bfeb <https://github.com/oemof/oemof-examples/commit/743bfeb>`_).
- Add a new tutorial for efficiency optimization of a thermal power plant using
  TESPy and PyGMO (`PR #220 <https://github.com/oemof/tespy/pull/220>`_).

  (`PR #220 <https://github.com/oemof/tespy/pull/220>`_).

Bug Fixes
#########
- Update the dictionary of busses, components and connections before every
  calculation. If a parameter is updated by user specification using the
  dictionary access method and the network object is copied, the dictionaries
  of the busses, components and connections point to a different object in some
  cases (`d2537ca <https://github.com/oemof/tespy/commit/d2537ca>`_).

Other Changes
#############
- Add network check at the end of
  :py:func:`tespy.networks.network_reader.load_network` function
  (`PR #212 <https://github.com/oemof/tespy/pull/212>`_).
