<p><em>Sourced from <a
href="https://github.com/Byron/gitoxide/releases">gix's
releases</a>.</em></p>
<blockquote>
<h2>gix v0.64.0</h2>
<h3>New Features</h3>
<ul>
<li>enable tracing with the new <code>tracing</code> feature in the
Cargo manifest.
That way, it's easier to directly enable tracing, instead of having to
resort to <code>gix-features</code>.</li>
<li>add <code>config::section::filter()</code> for the default section
filter.
Provide the default implementation to determine which configuration
sections should be trusted.</li>
<li>provide <code>config::credential_helpers()</code> function to
configure an invocation.
That way it's possible to use git credential helpers even without a
Repository instance.</li>
<li>export <code>gix_validate</code> as <code>validate</code>.
The crate appears in the public API of
<code>gix_index::State::from_tree</code>
but it's types weren't readily available.</li>
<li>add <code>PrepareFetch::with_ref_name()</code> to control which ref
is checked out.</li>
</ul>
<h3>Bug Fixes</h3>
<ul>
<li>
<p>make sure that <code>refs/heads/HEAD</code> isn't considered
conflicting</p>
</li>
<li>
<p>re-export <code>gix_validate</code> as it's now part of the public
API.
This allows calling <code>State::from_tree()</code>.</p>
</li>
<li>
<p>don't attempt negotiation without any refspec-mappings
Previously, when a shallow operation was specified, it was possible
to skip past the no-change test and attempt to negotiate even though
there was nothing to want.</p>
<p>This is now 'fixed' by simply aborting early if there is no refspec
mapping at all.</p>
<p>Further, it aborts as early as possible with a nicer error message,
after all, there is no use in having no mapping.</p>
<p>Note that it's explicitly implemented such that obtaining such an
empty
refmap is fine, but trying to receive it is not. That way, the user can
obtain information about the server without anything being an error.</p>
</li>
</ul>
<h3>Other</h3>
<ul>
<li><!-- raw HTML omitted --> gate parking_lot behind interrupt
feature</li>
</ul>
<h3>New Features (BREAKING)</h3>
<ul>
<li>
<p><code>gix-config</code> convenience initiative
A new <code>gix_config::AsKey</code> trait allows all
<code>gix_config::File</code> methods
to receive an implementation of <code>AsKey</code> instead of the tuple
of
<code>(section, subsection, value_name)</code>. This is the default, and
all
methods that take a tuple have been renamed to
<code>&lt;name&gt;_by()</code>, note the <code>_by</code> suffix.</p>
<p>The terminology was reworked so that <code>key</code> is now only
used to identify a value.</p>
</li>
</ul>
