<blockquote>
<h2>v4.4.6 (2023-02-21)</h2>
<p>Bugfixes - 4.4.6</p>
<pre><code>- Plugins are now able to access tox.ini config sections
using a custom prefix with the same suffix / name as a tox
  ``testenv`` - by :user:`masenf` (:issue:`2926`)
<h2>v4.4.5 (2023-02-07)</h2>
<p>Bugfixes - 4.4.5
</code></pre></p>
<ul>
<li>Ignore labels when tox will provision a runtime environment
(<code>.tox</code>) so that environment configurations which depend
on provisioned plugins or specific tox versions are not accessed in the
outer tox process where the configuration would
be invalid - by :user:<code>masenf</code>.
(:issue:<code>2916</code>)</li>
</ul>
<h2>v4.4.4 (2023-01-31)</h2>
<p>Bugfixes - 4.4.4</p>
<pre><code>- Forward ``HOME`` by default - by :user:`gschaffner`.
(:issue:`2702`)
<h2>v4.4.3 (2023-01-30)</h2>
<p>Bugfixes - 4.4.3
</code></pre></p>
<ul>
<li>Tox will now expand self-referential extras discovered in package
deps to respect local modifications to package
metadata. This allows a package extra to explicitly depend on another
package extra, which previously only worked with
non-static metadata - by :user:<code>masenf</code>.
(:issue:<code>2904</code>)</li>
</ul>
<h2>v4.4.2 (2023-01-25)</h2>
<p>Bugfixes - 4.4.2</p>
<pre><code>- Allow the user configuration file (default
``&lt;appdir&gt;/tox/config.ini``) to be overridden via the
``TOX_USER_CONFIG_FILE`` environment variable. Previously tox was
looking at the ``TOX_CONFIG_FILE`` to override the
user configuration, however that environment variable is already used to
override the main configuration - by
  :user:`masenf`. (:issue:`2890`)
<h2>v4.4.1 (2023-01-25)</h2>
<p>&lt;/tr&gt;&lt;/table&gt;
</code></pre></p>
