<h1>=========
Changelog</h1>
<ul>
<li>
<p>:release:<code>0.7.13 &lt;2023-01-13&gt;</code></p>
</li>
<li>
<p>:support:<code>- backported</code> Modernized the project:
s/Travis/Circle/ for CI,
README badges, <code>setup.cfg</code> removal, metadata refresh,
etc.</p>
</li>
<li>
<p>:support:<code>- backported</code> Dropped support for Python 2 and
Python &lt;3.6. This
includes various minor updates to work correctly with modern versions of
Sphinx (1.6 at the very least). Thanks to Adam Turner for a pile of
patches
here.</p>
<p>.. warning::
This change is backwards incompatible if you're on an old Python
version.</p>
</li>
<li>
<p>:support:<code>- backported</code> Tweak CSS somewhat for
compatibility with modern
Sphinx versions' base stylesheet.</p>
</li>
<li>
<p>:release:<code>0.7.12 &lt;2018-10-02&gt;</code></p>
</li>
<li>
<p>:bug:<code>-</code> On some browsers/platforms, 'badge'-style sidebar
elements were
displaying dotted underlines. This was unintentional and explicit
styling has
been added to remove them. Credit to Steven Loria.</p>
</li>
<li>
<p>:support:<code>- backported</code> Reorganize the
:doc:<code>customization page &lt;/customization&gt;</code> to break up
the now rather long list of &quot;variables and
feature toggles&quot; into additional sections; includes alphabetizing
those
lists, to make it a bit easier to find docs for a specific setting.</p>
</li>
<li>
<p>:feature:<code>132 backported</code> (partially via
:issue:<code>143</code>) Add a generic donation
badge/url option (visually powered by <a
href="https://shields.io/">https://shields.io/</a>) as well as a
service-specific donation option for <code>OpenCollective
&lt;https://opencollective.com&gt;</code>_.</p>
<p>We expect this to be followed-up on later with more service-specific
options
for services like Patreon. Thanks to Melanie Crutchfield for the report
and
Steven Loria for the initial patch.</p>
</li>
<li>
<p>:bug:<code>128</code> Remove Gittip/Gratipay output from the
<code>donate.html</code> sidebar
component, since the actual service has been insolvent since 2017. The
configuration options remain in place for the time being (to avoid
breaking
backwards compatibility) but no longer do anything. Thanks to Joe Alcorn
for
the report / original patchset.</p>
<p>.. note::
See the changelog entry for
<code>[#132](https://github.com/bitprophet/alabaster/issues/132)</code>,
which re-introduces a more generic
donation sidebar framework.</p>
</li>
<li>
<p>:feature:<code>142 backported</code> Add a <code>tidelift_url</code>
option, which when set
(default is <code>None</code>/unset) adds a small text snippet to the
<code>donate.html</code> sidebar component, linking to the given URL
string. Thanks
to Steven Loria for the patch.</p>
</li>
<li>
<p>:bug:<code>141</code> Fix a typo in the code-block font family, which
incorrectly
specified <code>Deja Vu Sans Mono</code> instead of <code>DejaVu Sans
Mono</code>. This would
primarily impact systems lacking the first two fonts
(<code>Consolas</code> and</p>
