</div>
<div class="section" id="v1-4-3-production-release-2020-07-04">
<h2>V1.4.3 (production release) 2020-07-04</h2>
<p>A huge effort, thanks to @stuarteberg Stuart Berg, has been made to make Ngspice and PySpice
available on Anaconda (conda-forge) for the Window, OSX and Linux platforms. Thanks to the
conda-forge continuous integration platform, we can now run unit tests and the examples on theses
platforms automatically. Hope this will make the software more robust and easier to run !</p>
<ul class="simple">
<li><p>PySpice is now available on Anaconda(conda-forge) as well as a wheel on PyPI</p></li>
<li><p>Added a post installation tool to download the Ngspice DLL on Windows and to check the installation.
It should now simplify considerably the PySpice installation on Windows.</p></li>
<li><p>This tool can also download the examples and the Ngspice PDF manual.</p></li>
<li><p>On Linux and OSX, a Ngspice package is now available on Anaconda(conda-forge).
Note that theses two platforms do not download a binary from Ngspice since a compiler can easily be installed on theses platforms.</p></li>
<li><p>Updated installation documentation for Linux, the main distributions now provide a ngspice shared package.</p></li>
<li><p>Added a front-end web site so as to keep older releases documentation available on the web.</p></li>
<li><p>fixed and rebuilt all examples (but mistakes could happen ...)</p></li>
<li><p>examples are now available as Python files and Jupyter notebooks
(but some issues must be fixed, e.g. due to the way Jupyter handles Matplotlib plots)</p></li>
<li><p>support NgSpice 32 API (no change)</p></li>
<li><p>removed @substitution@ in PySpice/__init__.py, beacause it breaks pip install from git</p></li>
<li><p>fixed some logging spams</p></li>
<li><p>fixed NonLinearVoltageSource</p></li>
<li><p>fixed Unicode issue with °C (° is Extended ASCII)</p></li>
<li><p>fixed ffi_string_utf8 for UnicodeDecodeError</p></li>
<li><p>fixed logging formater for OSX (removed ANSI codes)</p></li>
<li><p>reworded "Invalid plot name" exception</p></li>
<li><p>removed diacritics in example filenames</p></li>
<li><p>cir2py has been converted to an entry point so as to work on all platforms</p></li>
<li><p>updated Matplotlib subplots in examples</p></li>
<li><p>added a unit example</p></li>
<li><p>added a NMOS example (thanks to cyber-g) cf. #221</p></li>
