    <subfield code="a">&lt;a class="anchor" href="#changelog-for-v-016"&gt;&lt;span class="octicon octicon-link"&gt;&lt;/span&gt;&lt;/a&gt;Changelog for v 0.16

&lt;p&gt;Version 0.16 represents the culmination of 1 month of efforts, yet another step
in the current time-based release scheme.&lt;/p&gt;


&lt;a class="anchor" href="#features-added"&gt;&lt;span class="octicon octicon-link"&gt;&lt;/span&gt;&lt;/a&gt;Features added:

&lt;p&gt;This release brings the test coverage of the codebase over the 80% milestone for
the first time. It also features a faster substitution algorithm for symbolic
simulations, we empoly the tabulate module more extensively, producing a
prettier output (for example print_short() now prints a pretty table.)&lt;/p&gt;

&lt;p&gt;Internally, We removed occurrences of np.matrix, in favor of np.array,
according to the overall planned switch in the library. This should be
completely transparent to the user.&lt;/p&gt;

&lt;p&gt;A few changes that have been introduced are &lt;em&gt;incompatible&lt;/em&gt; with the previous
releases:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;The axis iterators utilities.log_axis_iterator and
utilities.lin_axis_iterator now follow the syntax (min, max, points).&lt;/li&gt;
&lt;li&gt;The solution method solution.asmatrix() has been renamed to
solution.asarray().&lt;/li&gt;
&lt;li&gt;We droppped the (undocumented) support for accessing singularities in
pz_solution as 'Re(p0)' and 'Im(p0)'. Hopefully, being
undocumented it had little use. Please use numpy.real(r['p0']) or
numpy.imag(r['p0']) to achieve the same result.&lt;/li&gt;
&lt;li&gt;Remove printing.table_print() for print(printing.table()).&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;We apologize about the above, we believe the technical debt we paid with the
changes above makes up for the discomfort to our userbase.&lt;/p&gt;

&lt;p&gt;Moreover, as in the previous releases, several commits were devoted to improving
the documentation: you can find the new, improved documentation online at
&lt;a href="http://ahkab.readthedocs.org/en/latest/"&gt;http://ahkab.readthedocs.org/en/latest/&lt;/a&gt;&lt;/p&gt;

&lt;li&gt;#29 - ahkab should now work well in IPython running under Python2 again.&lt;/li&gt;
&lt;/ul&gt;

&lt;/li&gt;

&lt;/li&gt;
