v0.0.19 (9 July 2021)
----------------------
The prior version of lifelib was erroneously packaged.
This version of lifelib is released to fix the packaging issue, and
has the same contents as v0.0.16.
To update lifelib, execute the command::
>>> pip install lifelib --upgrade
v0.0.18 and v0.0.17 are discarded due to packaging error.
v0.0.16 (14 February 2021)
------------------------------
.. warning::
lifelib v0.0.16 was not packaged correctly. Use v0.0.19 instead.
.. warning::
`modelx`_ needs to be updated to v0.12.1 for this version of lifelib.
- :doc:`fastlife ` project is added. See the project page for details.

v0.0.15 (6 December 2020)
------------------------------
.. warning::
lifelib v0.0.15 was not packaged correctly. Use v0.0.19 instead.
This release includes models updated from the previous version.
The updated models are:
* :doc:`/projects/simplelife`
* :doc:`/projects/nestedlife`
* :doc:`/projects/ifrs17sim`
* :doc:`/projects/solvency2`
The updated models produce the same results as the previous version's.
The updated models are much simpler than previous versions, thanks to
2 new enhancements introduced in `modelx v0.9.0`_ and `modelx v0.10.0`_.
One of the enhancements is ExcelRange introduced in `modelx v0.9.0`_.
Input data read from the Excel input file is now stored as *ExcelRange*
objects in the models.
The other enhancement is the introduction of *Relative Reference*.
Thanks to the introduction of the relative reference,
Space formulas in the models got simpler and easier to understand. Read
`this blog post `_
on modelx site to know more about how *Relative Reference* makes lifelib models simpler.
From this release, models are provided in the form of modelx models,
which are folders containing files and data to construct models.
Models are read into IPython sessions by
`modelx.read_model`_ function. See updated :doc:`/quickstart/spyder` section for how to read models.
Python scripts for building models are not provided from this release.
All the example notebooks now read models using `modelx.read_model`_.
Models from the previous release are also included in the projects.
Those models are files named "model_0_0_14.zip". The zip files
can also be read by `modelx.read_model`_ directly, and no unzipping needed.

v0.0.14 (18 April 2020)
-----------------------
This release reflects changes for models to run on `modelx`_ v0.5.0.
.. warning::
Due to backward incompatible changed introduced in `modelx`_
v0.5.0, models based on lifelib versions prior to this
release need manual changes in their source code.
See `commit 605802a`_ and `commit df083f6`_ for where and
how to make changes in such models.

v0.0.13 (27 Dec 2019)
---------------------
.. warning::
`modelx`_ needs to be updated to v0.1.0 for this version of lifelib.
- :doc:`smithwilson ` project is added. See the project page for details.
v0.0.12 (6 July 2019)
---------------------
.. warning::
`modelx`_ needs to be updated to v0.0.22 for this version of lifelib.
This version fixes the trouble resulted from erroneous packaging in v0.0.11,
and includes minor code improvements.
- Fix the packaging error in v0.0.11 (`Issue #6 `_).
- Update :mod:`~ifrs17sim.ifrs` to include the loss component logic.
- Fix the sign in :func:`~ifrs17sim.ifrs.AmortAcqCashflow`.
- Update :mod:`~simplelife.build_input` to make a better use of
updated ``new_space_from_excel``.
v0.0.11 (24 March 2019)
-----------------------
.. warning::
This version of lifelib should not be used, as the uploaded files in
`PyPI `_ were
not properly packaged and some older files were included
by mistake.
You will see an error when you try to run the default models.
For more on th error and how to fix it,
see `this discussion on github `_.
.. warning::
`modelx`_ needs to be updated to v0.0.21 for this version of lifelib.
- :doc:`/projects/simplelife-space-overview` notebook is added.
- The input file is renamed from "input.xlsm" to "input.xlsx" and redundant
data and macros are removed from the file to gain speed in reading.
- Parameter ``module_`` of Space's ``import_module`` method is renamed to ``module``.
- Reserved name ``_self`` is renamed to ``_space``.
v0.0.10 (2 February 2019)
-------------------------
- :doc:`/projects/solvency2` project is added. See the project page for details.
- :doc:`/projects/ifrs17sim_charts_lapsescen` notebook is added.
- Override formulas are included in :mod:`~nestedlife.nestedlife` and
:mod:`~ifrs17sim.ifrs17sim`.
- Update :doc:`/projects/ifrs17sim` model to pay out profits each period.
- Fix miscalculation in :func:`~ifrs17sim.projection.IntAccumCF`
in :mod:`~ifrs17sim.projection`.
- :mod:`~ifrs17sim.ifrs17sim` and :mod:`~ifrs17sim.ifrs` modules are
modified to correct discounting and surrender in nested projections.
v0.0.9 (5 August 2018)
----------------------
.. warning::
`modelx`_ needs to be updated to v0.0.13 for this version of lifelib.
Accordingly, Support for Python 3.4 and 3.5 is dropped. Now Python 3.6 or
3.7 is required.
- Due to an update in modelx, updating existing cells with ``new_cells``
method of Space no longer works.
Accordingly, ``new_cells`` in
:doc:`/generated_examples/nestedlife/plot_actest` and
:doc:`/generated_examples/nestedlife/plot_pvnetcf` examples are replaced
with ``set_fomula`` method.
Check `this commit on github `__
to see the exact changes.
- Due to a spec change in modelx, dynamic spaces now inherit their
parent spaces by default.
Accordingly, :func:`simplelife.simplelife.build`, :func:`nestedlife.nestedlife.build` and
:func:`ifrs17sim.ifrs17sim.build` are updated.
Check `this commit on github `__
to see the exact changes.

- :doc:`/projects/devguide/naming_convention` is introduced, and most source
functions and some space and modules are renamed to be consistent

cleaner and more readable, thanks to the introduction of
``space.cells[varnames].to_frame(args)`` expression.
