v0.3.3 - Maxwell’s Memory (July, 21, 2020)
++++++++++++++++++++++++++++++++++++++++++

New Features
############
- In some cases - especially large networks and many simulation runs within a
  a single script - the fluid property memorisation added a lot of calculation
  time for searching through the lookup tables of previously calculated fluid
  property values. It is now possible to manually specify whether or not the
  fluid property memorisation is performed.

  The memorisation benefits

  - networks using gaseous mixtures and
  - smaller networks using the HEOS back end.

  The memorisation slows down

  - very large networks and
  - usage of tabular back ends (BICUBIC or TTSE).

  In order to deactivate memorisation, add
  :code:`memorise_fluid_properties=False` on network creation, for example:

  .. code-block:: python

      from tespy.networks import network

      mynetwork = network(
          fluids=['BICUBIC::water'], memorise_fluid_properties=False)

  (`PR #211 <https://github.com/oemof/tespy/pull/211>`_).

Other Changes
#############
- Reorder network initialisation process for improved maintenance and faster
  performance (`PR #204 <https://github.com/oemof/tespy/pull/204>`_).
